Of the specimens of this species that were kindly sent to me by the 

 Rev. Mr. Hogan, those from Corsham differ somewhat from the above 

 in having the hands somewhat less elongate, and in the posterior pleo- 

 poda having the second articulation of the long ramus much shorter than 

 the first But this, as pointed out by Schibdte, is probably a sexual 

 distinction.

Eyes not visible. Superior antenna? having the flagellum longer than 

 the peduncle. Inferior antenna? having the flagellum as long as the 

 peduncle. First and second pairs of gnathopoda subequal, having the 

 propodos elongate, broader at the palm than at the posterior extremity ; 

 palm slightly advanced, and produced a little beyond the dactylos, 

 armed with a long spine a little anterior to the inferior angle of the 

 palm. 



Three posterior pairs of pcreiopoda having the dactylos long and 

 slightly curved, unguiculate, and furnished with a sharp tooth upon 

 the anterior margin.
