SCHMIDT, THE HERPETOLOGY OF PORTO RICO 185 



gphwrodaetylus grandisquamis Stejneger, 1904, Rept. U. S. Nat. Mus., 1902, p.

The following localities are represented by forty-five specimens in the 

 collection: Aibonito, Bayamon, Catano, Coamo Springs, Ensenada, Mari- 

 cao, El Yunque, and Mona Island. This species is found on Mona Island, 

 throughout Porto Eico, and on most of the Virgin Islands (Vieques, St. 

 Thomas, St. Croix, Tortola, Virgin Gorcla, Anegada). Stejneger, with 

 specimens from only two localities in Porto Eico (Luquillo and Ponce), 

 described the Porto Eican and Vieques specimens as distinct from the 

 Virgin Island form, as well as from that of Mona Island. He surmised 

 that it was confined to the lowlands, whereas the present series proves 

 that it reaches an altitude of at least two thousand feet. 



Barbour (1917, p. 98), after examining a considerable series of 

 Sphcerodactylus macrolepis from the Virgin Islands, expresses a measure 

 of doubt as to the distinctness of S. grandisquamis. Stejneger separates 

 S. grandisquamis and 8. monensis from 8. macrolepis solely on the size 

 of the scales, which he gives as 34-38 about the body in 8. grandisquamis, 

 46-48 in 8. monensis. In the series from Porto Eico under consideration 

 the variation is as follows : 



Scales about the body 32—36 — 10 11 1 8—52—50 



Number of specimens 2 8 3 4 5 2 



In five specimens from Mona Island the number of scales varies from 

 44-52. As 8. macrolepis is intermediate between 8. grandisquamis and 

 8. monensis, it is evident that the variation in the present series includes 

 all three supposed forms. There is probably a somewhat different range 

 of variation on the several islands, but the extremes are certainly included 

 in that of the Porto Eican series. Eeproduced tails have a much widened 

 series of median ventral scales. 



An egg, probably of this species, was found under a log at Aibonito, 

 August 21, 1919. It is white, discolored by stains, with a hard and 

 smooth shell, 6 x 4.5 mm. 



Anolis Daudin 



Anolis cuvieri Merrem 



Eleven specimens of this species were collected at Aibonito. Anolis 

 cuvieri has been taken at Aibonito, Catalina Plantation (El Yunque), 

 Humacao, Luquillo, Mayaguez, and Utuado. It is probably not found in 

 the arid southwestern corner of the island, but ranges quite generally over 

 the remaining part of Porto Rico. It is recorded from Vieques and
