Item Summary

Title: The Echinoidea Collected by the Royal Society of London Expedition to Southern Chile, 1958-1959
Authors: Pawson, David L.
Issue Date: Apr-1966
Publisher: University of Hawai'i Press
Citation: Pawson DL. 1966. The echinoidea collected by the Royal Society of London Expedition to southern Chile, 1958-1959. Pac Sci 20(2): 206-211.
Abstract: The collection comprises the species Arbacia dufresnei (Blainville),
Pseudechinus magellanicus (Philippi), and Loxechinus albus (Molina). Typical
temnopleurid epistrorna is now known to be present in juveniles of Pseudechinus
magellanicus, and the disposition of the ocular plates in the apical system in this
species is determined by the position of the anal aperture. The shallow water
echinoid fauna of southern Chile includes the endemic genera Loxechinus and
Tetrapygus, and genera with ant arctic (Tripylus) and circumpolar (Pseudechinus)
affinities.
