NO. 7 HERPETOLOGICAL COLLECTIONS COCHRAN I3 



SPHAERODACTYLUS VINCENTI Boulenger 

 Sphacrodactylus vincenti Boulenger, Proc. Zool. Soc. London, 1891, p. 354. 



A male, U.S.N.M. no. 79067, from Brighton, St. Vincent, August 

 14, 1929, measures 22 mm from snout to vent. It has a very distinct 

 escutcheon of dilTerentiated scales on the posterior surface of the ahdo- 

 men. The epidermis covering this patch of differentiated scales in 

 Sphacrodactyli is more opaque when drying than is the epidermis of 

 the surrounding ventral parts. When the epidermis is removed, the 

 diiTerentiated scales appear coarser and thicker than do the ordinary 

 ventral scales, and they are unpigmented and hence usually lighter in 

 color than the other ventral scales.

Laccrta igiiana Linnaeus, Syst. Nat. ed. 10, vol. i, p. 206, 1758. 



U.S.N.M. nos. 7921 1-6 from Los Robles, Margarita Island, Sep- 

 tember 8, 1929; no. 79229 from Orchilla Island, September 10, 1929; 

 nos. 79321-2 from Aruba Island, September 17, 1929. In these 

 examples there is a range of 46 to 58 in the number of enlarged scales 

 in the dorsal crest, and the femoral pores are between 13 and 17. None 

 of the individuals shows a tendency to have any of the median snout 

 scales enlarged into the conical, soft tubercles which supposedly 

 characterize the variety rhiuolopha. The following color notes were 

 made from living examples from Los Robles, Margarita Island, by 

 Dr. Bartsch : 



Head most intense green with a dark brown, almost black, spot on the middle 

 of the top, another below and a third behind the eye, typanum gray. Neck green 

 gold and striped with dark brown. Body green gold, marbled with white and 

 almost black spotted. Comb warm red on neck, tending gradually toward green 

 on the back. Underside of belly pale green spotted with various shades of 

 brown. Dewlap faintly rose, edged with green and dotted and dashed with 

 dark brown. Sides of body with zigzag, oblique bands of green, brown and 

 white in the order mentioned, from the back forward. Scales of front legs 

 green and brown, greener inside, with a whitish, greenish band on the shoulder, 

 edged by dark ciorsally. Hind legs like the front, whitish below. Tail green 

 with broad bands of brown, usually edged with whitish or light brown on the 

 posterior part, the light area being on the outer parts of the bands. The posterior 

 half of the tail has alternating broad bands of light and dark brown.
