One specimen, a female containing a number of rather large j'ellow 

 eggs; differing from I'elated species by its nuich narrower compressed 

 body, larger ev(\ more fully arched back and general coloration, and 

 in having teeth larger and more evident. 



This species is close to P. mentidls^ described in isTd by Doctor Gill, 

 from the Isthnuis of Panama. A comparison of our specimen with 

 i\\v type of that species shows it to differ in several important respects, 

 namely, the smaller dorsal and anal, somewhat smaller scales, shorter 

 snout, and in the coloration.
