LAMPROPS (?) BERINGI, new species. 



Ovigerous female. — Total length, 12.7 mm. 



Carapace about one-fifth of total length, its dorsal surface keeled 

 in front, flattened or faintly sulcate behind. A single oblique ridge

on each side of the carapace ends below on the antero-lateral tooth 

 and meets its fellow of the opposite side on the dorsal surface a little 

 behind the middle of the carapace. The pseudorostrum is very 

 short and blunt; the antennal notch is well-marked and rounded; the 

 antero-lateral corner projects as far forward as the 

 pseudorostrum and is sharply pomted. 



In the first legs the three distal segments are 

 subequal in length and the distal end of the carpus 

 extends slightly beyond the pseudorostrum in the 

 natural position. The second legs have the two 

 distal segments subequal and together equal to the 

 carpus. 



The telson is nearly one and a half times as long 

 as the last somite, with five or six lateral spines on 

 each side (not symmetrically placed) and three 

 apical spines of which the median is the longest. 



Peduncle of uropods about equal in length to 

 the telson, \vith rather slender spines on its inner 

 edge. Endopod nearly as long as peduncle, exopod 

 slightly shorter; second and third segments of en- 

 dopod subequal and together about three-fifths of 

 length of first segment. 

 Remarlcs. — In the absence of the male it can not be decided whether 

 this species should be placed in Lamprops or in Hemilamprops, 

 although the presence of a well-marked antennal notch in the front 

 margin of the carapace suggests the former of these genera. In hav-
