Mottling is characteristic of the soils, and gley horizons occur in the more hydromorphic soils in the group . As the soils become hydromorphic, soil color values increase and structures deteriorate. Halloysite is the dominant clay mineral in the less hydromorphic soils and montmorillonite is dominant in the more hydromorphic soils of the group . The montmorillonite is iron-rich and in one soil has the formula (XO.74Ko.1l) (Si7.52Al0.48)^IV (Al1.85Fe1.60^3+MgO.35Ti0. l0 )^VI O20(OH)4. Hydrated halloysite occurs in all the soils studied, but it is most abundant in the more hydromorphic soils. Although the soils are derived from different alluvial materials, the trend of increasing montmorillonite and increasing hydrated halloysite with increasing hydromorphism is clearly related to the pedogenic processes operating in the soils. Similar mineralogical trends are found with increasing depth in each soil.

The seismic well-logging technique gave a complicated velocity-depth profile, with higher velocities associated with reef limestone and lower velocities associated with mud deposits. The seismic refraction method showed a simpler velocity-depth profile with only a few distinct layers. The seismic reflection method corroborated the simpler profile obtained with the refraction method. The two profiles were reconciled, as the complicated profile can be averaged out into the simpler profile. The averaging-out process can be applied to the whole sedimentary column so that a P-wave velocity value may represent the sedimentary layer at any given locality. However, no single value can be assigned as typical for sedimentary layers for the entire Hawaiian area. The velocity values depend upon the composition of the layer, which is made up of varying proportions of mud, reef limestone, and weathered basalt. Layer 2 of the oceanic crust in the Hawaiian area has a rather uniform character, with seismic velocities ranging from 4.8 to 5.1 km/sec, and thicknesses from 4 to 8 km.

Schismorhynchus, genus novum, is erected for Muraenichthys labialis Seale. The genus Muraenichthys contains 19 known species in the tropical, subtropical, and temperate Indo-Pacific Ocean. M. chilensis, a new species showing affinities to southern Australian congeners, is the first known from the New World. The present distribution of Muraenichthys and of the closely related genera Schultzidia and Schismorhynchus is perhaps explained by paleogeography, paleoclimatology, and adult habitat preferences. Muraenichthys species may be grouped by differences in posterior nostril condition, dentition, and head pore placement. The following changes in taxonomy are proposed : Leptenchelys pinnaceps Schultz = Callechelys melanotaenia Bleeker. Muraenichthys tasmaniensis McCulloch and Scolenchelys tasmaniensis smithi Whitley = Muraenichthys vermiformis Peters. M. ogilbyi Fowler = M. macropterus Bleeker.

Scarus dubius and S. perspicillatus are two Hawaiian species that exhibit envelope-building behavior. Laboratory experiments indicate that envelope formation is promoted by darkness, and is inhibited by constant light. The completed envelope is a transparent, mucous cocoon surrounding the fish. A mass of glandular tissue was found in the buccal cavity of S. dubius and S. perspicillatuS. It is suggested that this tissue is the envelope-producing gland.

Phascolosoma scolops Selenka and DeMan is the main component of the diet. Phascolosoma sp. cf. P. heronis Edmonds and Aspidosiphon elegans Chamisso and Eysenhardt are also eaten. This is the first report of the nature of the food of a member of the family Mitridae. Mitra litterata belongs to a distinct trophic subweb from other co-occurring predatory gastropods of similar size and population density-Morula granulata (Duclos), which preys mainly on herbivorous gastropods, and Conus spp., which eat herbivorous polychaetes.

The gastropod shell inhabited by a hermit crab represents a very discrete, definable portion of the ecological needs of every animal. A hermit crab must have protection for its soft abdomen or it will rather quickly be eaten. In addition, the ritualized shell fighting behavior patterns of hermit crabs (Hazlett, 1966a, 1966b, 1967) offer an easily observed specific behavioral parameter which reflects the extent of interspecific vs. intraspecific competition for this ecological factor.

The writer in 1938 made collections of the flora of Rotuma Island, an isolated, low, volcanic island that is situated about 300 miles north of the Fiji Archipelago. Only one species of Cyrtandra was discovered there, but it was notable in being a halophyte and in being poisonous. The nearest high land is in Fiji, so it is not surprising that the closest relative of the Rotuman species is one found in Fiji.

This taxon is the only representative of the Bonnemaisoniaceae (Nemaliales, Rhodophyta) collected at Amchitka. It is distinguished from other members of the family by the presence of macroscopic tetrasporophytes with compound tetrasporangial stichidia arising along the margins of laminate axes. These tetrasporic branchlets are homologous to indeterminate branches. Gland cells with brownish contents are present over the surface of the laminate axes and also on the stichidia . Although numerous specimens have been collected, tetrasporic plants are the only fertile stages observed so far.

The sediment was cored by free-fall device in a water depth of 4,795 meters. This corer caused relatively little disturbance to the sedimentary layers of the core, which consist of thin Quaternary deposits overlying Miocene with well-preserved radiolarian assemblages. The microfaunal sequence is documented herein.

M. A. Beguin. The greater part of these represent a species which had been given a new name in manuscript by C. A. Backer, but which he evidently never published; this name was based on the name of the island Ternate. Recently (Stone, 1970) I have described this as a new species, closely related to Freycinetia insignis Blume. Not all the specimens collected by Beguin are of this species, however, and the several mentioned here appear to represent a different species, not very close to F. insignis (which pertains to Sect. Blumeella), but rather to F. arborea Gaud . and its nearest relatives, which together form Sect. Freycinetia. In this paper the name Freycinetia leptostachya is proposed for th is interesting new endemic of Ternate.

It is one of the so-called uninodal pines - that is, its winter bud elongates to form an unbranched axis bearing lateral long shoot buds only near the distal end. However, it is remarkably prone to lammas growth or summer shoots (premature elongation of a newly formed dormant bud) and to several other anomalous forms of behavior. Some of these strongly affect tree form; others are economically unimportant but serve to illustrate further the morphological plasticity within the genus Pinus. The observations reported here were made in early March 1969, in natural stands, plantations, nurseries, and a seed orchard.
