The species of this genus are very difficult to separate, espe- 

 cially when they have been kept in spirits for some time. In the 

 ' Zoological Miscellany' I attempted to divide them by the form of 

 the second labial shield and head-shield, but these characters ap- 

 pear to vary with the individual specimens. 



* Body olive or gray ; labial plates 9 or 10 on each side, the 3 or 4 



hinder ones smaller.
