Leg 5 (figs. 146A, 147/) remarkable by greatly lengthened baso- 

 endopodite, which reaches apex of exopodite. 4 strong setae along 

 baso-endopodite: 2 at apex, 2 along internal border, basal of which is 

 very strong. Probably 5th seta, or long hair, near insertion of inter- 

 coxal plate on baso-endopodite. External lobe long, with strong seta. 

 Exopodite elongated triangular or ovate, with 5 short setae. 



Color completely faded, transparently whitish. No eye or pig- 

 mented spots observed. 



Remarks. — Though the species shows certain points of resemblance 

 with Onychocamptus and Klieonychocamptus, it has such a funda- 

 mentally different setal formula that I have been forced to place it in 

 a new genus, the aflEinities of which, because of the absence of males, 

 is unfortunately obscure. 



Four female specimens of this new species were washed from sponges 

 from the lagoon at Ifaluk Atoll; the depth at which they were obtained 

 is not given. 



The curious structure of the legs and particularly the setal formula 

 have been checked in all four dissected specimens and have been 

 found to be constant.
