37. F. senrisetifera Glasscott. 
In Cliara from East Swamp, South Bass Island. 
Hood (’95 ) holds that this species is identical with Furcularia eva of Gosse. My specimens did not 
have the large anterior dorsal hump which Gosse mentions in his description and figures prominently, 
so that I feel it necessary to accept Miss Glasscott’s name, the specimens agreeing with her figures.
