This animal in its general form differs considerably 
from the type of tlie genus, which is round and smooth, 
while this puts on an angulated appearance. The head 
is produced a little in front, the back is slightly carinated 
through the entire length of the animal, the tenth seg- 
ment (N) of the body is posteriorly produced to a tuber- 
cle, and a deep sinus indents the anterior dorsal portion 
of the next, which is also posteriorly elevated into a long 
tubercular ridge.
