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 Montagua ; 

 but they have not hitherto been satisfactorily examined.
