About forty specimens. 



Specimens of Cubaris ArmadUUdium pacifica Borradaile were sent 

 to me from the Museum of Zoology, Cambridge, England for compa- 

 rison with my specimens and they were found to be specifically the 

 same. I have redescribed the species, because in the original descrip- 

 tion of C. pacifica (Proc. Zool. soc, London, 1900, p. 79(), pi. 51) the 

 uropods were not correctly mterpreted.
