Description. — This species is naturally more closely allied to A(jo- 

 nostoma plicatih than to Mvrjil, but differs from it in having no 

 teeth at all in the jaws, except that in specimen n. the band of 

 papilla? passes into a series of fine moveable teeth anteriorly in the 

 upper jaw. The head and especially the body and tail are com- 

 pressed ; the greatest depth of the body nearly equals the length of 

 the head, and is contained four times and a half in the total length.
