face of the lower arm, none of these scales being much larger than the 

 largest of the ventrals; anterior scales of femur and tibia smooth, 

 similarly enlarged, gradually diminishing posteriorly and below ; scales 

 covering hands and feet above enlarged, perfectly smooth; digital 

 expansion wide, about nineteen lamellae mider second and third 

 phalanges of fourth toe, about thirty-five under the whole toe; tail 

 moderate, slightly compressed, with very indistinct verticils, every 

 ninth or tenth row of scales more vertical but not enlarged, the 

 intervening scales in curving or irregular rows, the whole surmounted 

 by a weakly serrate caudal crest, with five triangular, keeled and 

 pointed scales to a verticil, the first and fifth quite small, the others 

 subequal; skin of gular fan naked, set with distant series of small, 

 flat scales considerably smaller than the ventrals; edge of fan not 

 thickened posteriorly; postanal scales scarcely developed; no distinct 

 nuchal or dorsal folds (in type specimen). 



"Dimensions. — Head and body, 48 mm.; tail (defective), 47+ mm.; 

 snout to posterior ear, 14 nmi.; snout to center of eye, 8.5 mm.; 

 width of head, 9 mm. ; foreleg, 22 mm. ; hindleg, 40 mm. 



"Color (in alcohol). — Upper surfaces of head and back plumbeous, 

 turning to pale china-blue above the shoulders and becommg azure 

 blue on the center of the head, deepening to dark cerulean on the 

 occipital scale; some faint gray mottlings, suggesting transverse bars 

 across the back, more prominent on the head where they form a dark 

 interorbital bar and outline the posterior orbital region ; a few scattered 

 gray marks on the temporal region; upper parts of legs and tail pale 

 olive gray with faint irregular darker spots and bars; ventral surface 

 pearl gray, the scales powdered with minute black dots; skin of 

 dewlap claret brown on the sides lightening to buff pink posteriorly 

 and in the center, its scales pearl gray with minute dark dots. 



"Paratypes. — Three adult specunens, all of them males, were taken 

 at the same time and place as the type (M.C.Z. 37518-9 and U.S.N.M. 

 95122). 



"Relationships. — The new subspecies shows its close relationship to 

 Anolis distichus dominicensis of the mainland of Hispaniola particu- 

 larly in its coloration, as it lacks the prominent scapular spots and 

 lines which usually characterize the subspecies from Beata and Gonave 

 Islands respectively. The scaling of the tail, the projection of the 

 canthus rostralis and other features separate the Isle Vache species 

 clearly from its neighbors on the mainland." 



Specimens examined. — As listed in table 26.
