ART. 24 SOUTH AMERICAN SNAKES AMARAL 13 



The lesser number of ventrals of this specimen, as compared with 

 Boulenger's figures (232-236), may be related to the sex. No. 51512 

 sent from Canon Verruga, by C. H. T. Townsend; female, sc. 19; 

 V. 227; c. 79 pairs. 



53. PSEUDOBOA CLOELIA (Daudin)

 Oxyrhopus cloelia Guenther, Cat. Snakes Brit. Mus., 1858, p. 189. — Bou- 



LENGER, Cat. Snakes Brit. Mus., vol. 3, 1896, p. 108. 

 Pseudoboa cloelia Amaral, Rev. Mus. Paulista, vol. 14, 1924, pp. 11-12. 



Ecuador. — 1 specimen, No. 20622, collected by Mark B. Kerr, 

 lab. 7 (3,4); t. 2 + 3; sc. 19; c. 91 p aire plus 3. 



Venezuela. — 1 specimen. No. 32218, sent from Caracas by Capt. 

 G. Wayright. 



Brazil. — 2 specimens No. 39061 sent as Khachidelus hrazili from 

 Butantan, Sao Paulo, by Dr. V. Brazil: lab. 7 (3, 4), t. 2 + 2; sc. 19. 

 No. 11,384 sent from Rio by J. R. Moran: lab. 7 (3, 4), t. 2 + 2; sc. 19. 



This specimen as well as No. 20622 shows that the disposition of the 

 subcaudals is variable and consequently does not warrant the divi- 

 sion of the genus Pseudoboa into Pseudoboa and Cloelia as accepted by 

 most of the North American herpetologists.

 Pseudoboa neuwiedii.
