preceding. Bands of forehead obsolete. Belly with small, ill-defined, 

 scattered dots. Markings darker. Ventrals 148 -{- 1 -{- 46 pairs. 



c. Back lighter colored ; marks of head and body distinct ; band 

 on forehead; abdomen much flecked and spotted with brown. Ven- 

 trals 149-fl-f 42 pairs. 



d. Smallest specimen. Bands on head and body most distinct. 

 The bands from the flanks, becoming more faint, extend across the 

 abdomen. Ventrals 150 -j- 1 -j— 42 pairs. 



The smaller of these have more of dark on the lower surface, and 

 the markings in general more distinct. Though the marks do not 

 become indistinct, there is a fading out of the central portions of the 

 bands which eventually gives the appearance of twice the number. 



Herpetodryas carinatus (L.) Schleg. 



Differing very little, if at all, from specimens from the Ucayale 

 River. The two keels and the light colored dorsal band are present. 

 Ventral scuta 158 -J- 2; subcaudals 126 pairs. 



Oxyrhopus petolarius (L.) D. and B. 



Var. Sebce D. and B. 



One example is of medium size, the other very small. The first is 

 marked by twenty-four half rings of black between the head and the 

 vent; and the hinder abdominal scuta are sprinkled with brown. 

 Subabdominals 205 -j- 1. Twenty-six half-rings occupy the body of 

 the smaller specimen ; among these there is rather more irregularity 

 than in those of the first. Two upper labials are united on one side 

 of the head. Subabdominals 223 -j- 1; subcaudals 85 pairs. On 

 the tails the black rings are complete. The half-rings are wider 

 than the red spaces.. Both specimens are irregular in the markings 

 of the middle of the body. 



Eteirodipsas annulata (L.) Jan. 



a. A single anteorbital on one side. Ground color a reddish 

 brown; lateral series of spots reduced in size. Subabdominals 173 

 -j- 1 pairs; subcaudals 74 pairs. 



b. Ground color greyish brown ; spots similar to those of preced- 

 ing. Subabdominals 1 70 — j— 1 pairs ; subcaudals 78 pairs. 



Elaps semipartitus D. and B. 



This specimen agrees well with the figure and description given by 

 Prof. Jan of E. multifasciatus. There are fifty-seven black rings — 

 two of them on the tail ; on the upper side of the tail, behind the 

 last ring, there is a rounded spot and the tip is black ; the muzzle is 

 black ; the throat spotted. A single irregular ring is seen on the
