the meros and carpos, against which apparently it impinges 
and between which it is received. 
Pereiopoda all wanting, except one of the fourth pair 
(which, on account of its brittleness, went to pieces during 
dissection), which was about one third as long as the body, 
and the joints of which were rather slender and were sparingly 
furnished with short almost spinose setz. 
Pleopoda slender. 
First and second uropods reaching nearly to the extremity 
of the third pair. (Unfortunately, owing to the fragile state 
of the specimen, these appendages were broken up during 
dissection, so that details could not be satisfactorily settled.) 
Telson apparently very short, cleft at the apex, and each 
side tipped with a very short spine (not well made out). 
Length 4 millim. 
Hab. Vaken with the dredge in about 8 fathoms in the 
Bay of Islands.
