PL. Ill, PIGS. 32-37. 
Body elongated, flattened, widest in the middle, tapering 
uniformly in both directions, first and last segments very 
narrow; middle third above, slightly convex; elsewhere, 
both above and below, flattened. 
Head (f. 32) wider than long, very convex, bluntly 
rounded in front, posterior angles rounded, posterior mar- 
gin very slightly convex, lateral margins convex, widest 
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 first 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 eo far that the 
feet on each side form one-third of the width of the body.
