Title: A New Species of Clypeaster (Echinodermata, Echinoidea) from San Felix Island, with a Key to the Recent Species of the Eastern Pacific Ocean

Citation: Serafy DK. 1971. A new species of Clypeaster (Echinodermata, Echinoidea) from San Felix Island, with a key to the recent species of the eastern Pacific Ocean. Pac Sci 25(2): 165-170.
Abstract: Clypeaster isolatus sp. nov. is described from 61 specimens taken off
San Felix Island. It is distinguished by its concave oral side, moderately high test
(23 to 36 percent of the test length), broad paired petals, primary spines without
a hyaline point, short, stout aboral primary spines and three to six primary tubercles
on the ridge between the pore pairs. Data on test morphology are given for use in
analysis of intraspecific variation. The new species is most closely related to
C. australasiae from southeastern Australia. This affinity to the Australian fauna
supports the theory of west-wind-drift dispersal.
