3. Leptochelia sp. (Plate LI. figs. 2-2 c.) 



The collection contains seven female specimens of a Leptochelia 

 near to, and perhaps identical with, L. minuta Dana, which was 

 described from the male only. There are, however, well-marked 

 differences between the present specimens and Dana's, besides 

 that of the chela?, which is known to be a sexual one. Of these 

 differences the most prominent are those affecting the uropods. 

 The following is a description of the animals : — 



Head large, equal to the three succeeding segments. 



First antenncB not longer than the head, of four simple joints. 



Second antenna of five joints and a minute end-joint ; the second 

 joint bearing on the inside a spine which is two-thirds the length 

 of the much narrower third joint. 



Chelipeds fairly strong, outreaching the head by the hand and 

 wrist, about half the total length of the body ; the hand as long 

 as the wrist but rather narrower. 



First walking-leg with the dactyle very long, longer than the 

 preceding joint. The remaining dactyles not so long. 



Uropods with the inner branch five-jointed, the outer one- 

 jointed. 



Colour in spirit, white. 



Length of the longest specimen, 3-5 mm.
