REPTILIA. 309 



land specimens, — I have none for actual comparison. Fielden (Zoologist, 1889, 

 p. 297) contributes an excellent account of this species, its habits, etc. It occurs 

 also in the Guianan subregion of South America. 



Garman's name, C. copii, based upon three specimens M. C. Z., No. 6,076 

 from Barbados, has no standing in nomenclature, since it is a nomen nudum. 



Aimiva auberi Coctbau. 



Cocteau, Sagra's Hist. Cuba. Rept., 1843, p. 74, pi. 6. Boulenger, Cat. lizards Brit, mus., 1885, 2, 

 p. 356. 



This species is widespread in Cuba, to which island it is confined. There 

 are specimens in the Museum from Santiago, Bahia Honda, and Puerto Principe. 

 Near the latter town I found it very common, running about over the sun-baked 

 ballast of the railroad line. Like its congeners, it prefers open, dry plains, with 

 plenty of exposed rock for basking. On my last trip to the island I found it 

 common near the beach between Morro Castle and Cojimar near Havana, and 

 met with it sparingly at San Diego de los Bafios, Herradura, Pinar del Rio, 

 and Madruga. 



Ameiva dorsalis Gray. 



Gray, Ann. mag. nat. hist., 1838, 1, p. 277. Boulenger, Cat. lizards Brit, mus., 1885, 2, p. 357. Bar- 

 bour, Bull. M. C. Z., 1910, 52, p. 298. 



An interesting species, confined to the island of Jamaica, where it has 

 grown rare and difficult to obtain owing to the reptile-devouring habits of the 

 introduced mongoose. 



Ameiva thoracica Cope. 



Cope, Proc: Acad. nat. sci. Phila., 1862, p. 64. Boulenger, Cat. lizards, Brit, mus., 1885, 2, p. 356. 

 Rosen, Lunds univ. arsskrift, 1911, 7, no. 5, p. 37. 



A common species throughout its range, which includes the Bahaman 

 Islands of New Providence, Eleuthera, and Andros. Cope (Proc. U. S. nat. 

 mus., 1887, 10, p. 438) records a specimen taken by Townsend (Cruise of the 

 Albatross) , at Great Abaco. Its occurrence on this island is nevertheless prob- 

 lematical. In 1904, Allen, Bryant, and I searched diligently for it at various 

 stations on the island, without result. 



Ameiva chrysolaema Cope. 

 Cope, Proc. Acad. nat. sci. Phila., 1868, p. 127. Boulenger, Cat. lizards Brit, mus., 1885, 2, p. 355. 



Confined to Haiti; a distinct form, related to the Bahaman A. thoracica. 

 Mr. W. M. Mann obtained many examples near Manneville.
