OPHIDIA. 



Stenosioma. 



Ogmius vakians. Oxyrhina varians Jan. This genus is strongly 

 glyphodont like Stenorhina. Prof. Jan considered it is isodont. His 

 name OxyrMna has been used variously before, on which account I pro- 

 pose the name above given. For a synopsis of genera allied to Ogmius. 

 See Silliman's Journ. Sci. Arts, 1864, 457. 



Stenorhina ventralis, D. B. A form with series of dots on the 

 scales, confirming the identity of the lined var. freminvillei with the 

 species.

Cystignathxjs melanonotus, Hallow. 



Cystignatiius gracilis, D. B. Not distinguishable from specimens 

 in the Mus. Compar. Zoology from Uruguay, except in less depressed 

 extremity of the muzzle. The same species from Yera Cruz. 



SCYTOPIS ALLENII, Cope. 



Fingers free and teeth in fasciculi between nares and otherwise gener- 

 ally as in P. xsignatus; but the muzzle is broadly rounded, there is a 

 black band from eye to middle of sides, followed by numerous large black 

 spots on yellow ground ; femora not cross- barred above, with large light 

 spots on black ground. 



The black scapular bars of this species are broad, and are not angulated 

 and converging as in S. xsignatus, but are parallel ; two black bars on 

 sacral region diverge towards the groin. There are several black spots 

 in the axilla, and longitudinal black line on front and back of l^umerus 

 and three on front and under side of humerus. Tibiae vermiculated on
