are similar; each is strongly recurved, S-shaped, with the basal 

 article thickened, cylindrical, but not greatly enlarged as are 

 those of the four posterior pairs. The dactyli are strong, curved, 

 pointed, hook-like, closing upon the propodal and carpal joints. 

 The fourth to seventh pairs of legs, inclusive, successively increase 

 in size and each has the basal article greatly enlarged, with the 

 outer side expanded, into a thick process with rounded outer mar- 

 gin. On the fourth pair of legs this process is of moderate size, 

 but on the fifth, sixth and seventh pairs of legs it is successively 

 much more expanded. The dactyli are similar to those of the first 

 three pairs of legs.

Remarks : For full discussion of this species, consult : Boone, 

 Lee, Vol. Ill, Bulletin of the Vanderbilt Marine Museum, p. 203, 

 pi. 77, fig. A, 1930. 



Material examined: Two ovigerous females and one male, 

 taken with submarine light, Conway Bay, Galapagos Islands, July 

 28, 1931. One large female, taken at Southport, Queensland, 

 Australia, September 24, 1931. 



Notes : The male of this species is not asymmetrical as are the 

 females, and has its median segments narrower, their lateral con- 

 tour more nearly forming parallel lines, whereas the female con- 

 tour is more convex. 



The larger female, approximately an inch long, is carrying 

 from 150 to 200 large, tough-skinned, opaque, spheroidal eggs.
