Body elongated, flattened, widest in the naiddle, tapering 

 uniformly in both directions, first and last segments very 

 narrow; middle third above, slightly convex; elsewhere, 

 both above and below, flattened. 



Head (f. 32j wider than long, very convex, bluntly 

 rounded in front, posterior angles rounded, posterior mar- 

 gin very slightly convex, lateral margins convex, \videst 

 at posterior third. Eyes large, circular, black, situated at 

 the widest part of the head, nearly lateral. 



Antennae, inferior slightly longer than superior, all fusi- 

 form, stout, not as long as the head. The flrst segment 

 is longer than the second ; it bears three pairs of tenta- 

 cular cirri. The first pair originate close to the lateral 

 margin of the head, the second, back of and a little within 

 the first, the third, under the second. The second seg- 

 ment bears one pair of cirri (the 4th). The second pair 

 are the longest, reaching back to the fifth segment. The 

 others are about half as long. They all arise from short 

 cylindrical basal articles. Diameter nearly uniform to 

 near the end, where they taper slightly to a bluntly rounded 

 termination. 



The incisions for the feet extend inward so far that the 

 feet on each side form one-third of the width of tbe body.
