112 EEPTILES AND BATRACHIANS 



small, keeled granules, larger on the snout. Dorsal scales 

 small, keeled ; those on the flanks larger ; those on the 

 belly twice as large as the vertebrals, smooth. A small 

 spine-bearing scale above the middle of the eye. Tail 

 round, covered with large smooth scales, with a median 

 series of larger ones below. 



Brownish with faint small spots of darker which show 

 tendency to form longitudinal lines on head, flanks, and 

 base of tail. Lips mottled with brown and lighter color. 

 Two streaks on each side of the base of the tail. Lower 

 surfaces lighter, puncticulate with brown on the free edges 

 of the scales. 



This species bears much resemblance to S. notaius in 

 shape and coloration ; the dorsal scales, however, are only 

 about half as large as in that species. The keels are 

 sharper, the snout broader, and the colors darker than in 

 8. argivus, 



SPHiERODACTYLUS DECORATUS Sp. n. 



Head short ; snout blunt pointed, as long as the distance 

 between the eye and the ear opening, equal to length of 

 orbit. Ear opening oval, vertical, as large as the digital 

 expansion. Rostral moderately large, with a median cleft 

 above, between the nostrils in contact with a series of four 

 internasals. Submental scales comparatively large. Head 

 covered with small granules, convex or slightly keeled, 

 larger on the snout. Dorsal scales minute ; laterals lar- 

 ger ; ventrals largest, flat. Caudal scales larger than dor- 

 sals, smooth, lower largest. 



Brown, with a white band across the parietals ; a second 

 white band behind the occiput encircles the neck and is 

 separated from a third, in front of the shoulder, by a black 

 band across the neck in which a small white spot appears 

 at each side of the vertebras. Five white bands cross the
