SALMACOPSIS.

 Type-species, Salmacopsis olivacea Doderlein, 1885, 1. c. 



Little need be said regarding this genus, which appears to be well marked 

 and characteristic of the Japanese fauna. Examination of the type-specimens 

 of Yoshiwara's species " pulchellimus " shows that that species is based wholly 

 upon specimens of Mespilia globulus. One of the specimens is peculiar in that 

 the spines are almost uniformly green and the outer series of pore-pairs, usually 

 conspicuous in Mespilia and in this specimen present at the ambitus, disappears 

 entirely abactinally so that most of the younger ambulacral plates are made up 

 of only two elements. Since Yoshiwara's species has no standing the genus 

 remains as it was when established, monotypic.

The specimens at hand range from 19 to 26.5 mm. in diameter and are 

 thus somewhat larger than Doderlein' s. They are also somewhat greener in 

 color, though none of them is conspicuously green, even on the bare interambu- 

 lacral areas. As the species has never been figured, photographs, as well as 

 drawings of the abactinal and actinal (in part) systems are given.
