In general aspect this animal resembles a species 
of the preceding genus. The head is furnished with a 
straight rostrum, and the anterior lateral margin is pro- 
duced anteriorly to a point in a straight line, further in 
advance than the rostrum. The body of the animal is 
smooth ; but the eighth, ninth, and tenth segments in- 
dicate a slight projection posteriorly on the dorsal sur- 
face. The eyes are probably like those in Montagna ; 
but they have not hitherto been satisfactorily examined.
