be noted that the scale counts are those oi B. tridactylus, but it is clearly 

 not that form, since the dorsal scales are overlapping and there is no inter- 

 parietal plate. 



Gymnophthalmtis sumichrasti (Cope). — Bolivar to 600 feet; Tucurinca 

 (Rehn and Hebard) ; Valencia; Badillo. The specimens, five in number, 

 were taken on the ground under leaves, except that' one of two specimens 

 captured at Bolivar was found in the grass in a pasture. They are secretive 

 and very difficult to capture, for they are mostly active only when the sun 

 is shining, or at least are best seen then, and are usually observed slipping 

 about among the leaves. 



The scutellation does not conform to the description given by Boulen- 

 ger"^ as shown by the following table: 



It will be seen that the numbers of. scales on the median dorsal line are 

 those of G. quadrilineatus, and that the number of longitudinal scale rows 

 may be either 13 or 15 or intermediate. In the specimens with both 13 and 

 15 rows an extra row is added on the sides about half-way between the fore 

 and hind limbs. In four specimens the scales on the base of the tail are 

 smooth as given for G. quadrilin,ea\tus, but in one specimen they are dis- 

 tinctly keeled. In the two specimens in which the tail is intact the scales 

 of the distal fourth of this appendage are keeled. The coloration is as 

 described by Boulenger, except that the ventral scales may bear round, black 

 spots. 



Amphisbaena fuUginosa Linnaeus. — A single specimen taken on San 

 Lorenzo at an altitude of 4,000 feet, crawling along the ground in the forest 

 at daybreak. A second individual was seen in the same locality. 



Mabuya agilis (Raddi). — Don EWego; Arroyo de Arenas; Valencia; 

 Las Pavas. Only found in regions of dense forest, but there taken in open 

 as well as shaded places. 



Serpentes 



Helminthophis petersii Boulenger. — Fundacion ; Valencia. Taken under 

 logs in dry forest at Fundacion and in the flood-plain forest at Valencia. 



The two specimens secured have 22 rows of scales. Dr. Boulenger 

 has advised me that he was in error in ascribing 20 rows of scales to the 

 species, the type specimen having 22 rows. 



Lcptotyphlops macrolepis (Peters). — A single, slightly mutilated speci- 

 men found dead in the dry woods at Bolivar is referred to this species. It 

 differs from the description given by Boulenger^^ in that the second labial 

 reaches the eye, but it differs from L. myopica in the proportions and in
