REPTILIA. 327 



He shows how excessively these vary in color, his three examples from Grenada 



differing much from one another. The same is true of Allen's specimens. There 



is, then, no evidence, either in squamation, or coloration, of the formation of a 



local race of this species upon Grenada. Boulenger (Proc. Zool. soc. London, 



1891, p. 355-356) records the finding of specimens on St. Vincent and Becquia. 



No mention, however, was made of these specimens in the Catalogue of snakes 



in the British museum, the last volume of which, with addenda, did not appear 



until 1896. 



( - Boa g-renadensis, sp. nov.) 



Type:— No. 7,991, M. C. Z., St. George's, Grenada, August 29, 1910, G. M. 

 Allen, collector. Another example, taken August 20, No. 7,990, M. C. Z., is a 

 cotype. 



Boulenger (Cat. snakes Brit, mus., 1893, 1, p. 100) records four specimens 

 of what he calls Corallus cookii var. C. from Grenada. These alone, among 

 all his series, are characterized by being yellowish brown above, uniform or with 

 mere traces of dark markings; belly yellow, without spots. Allen brought back 

 two examples, both from St. George's, Grenada; and as these agree in coloration 

 with what Boulenger has described, there can hardly be reasonable doubt but 

 that a local race, with characteristic color, has become differentiated upon this 

 island. The scale counts for Boulenger's specimens follow: — 



41 268 4 o270 41 264 4 „253 

 ^ tl 101) ^"lO^ ^ L 105' ^°105 



The type, M. C. Z., No. 7,991, counts 45nf, while the other example has 43 

 scale rows, but was damaged so that the other counts can not be made. The 

 range for these six is, then, 41-45 fnrzfii. This does not vary far from a simi- 

 lar series from other localities. Garman did not find this snake on Grenada. 

 According to Allen, it is known locally as "sarpint" in contradistinction to 

 "snake," this latter name being confined to the Racer. For the use of Boa 

 instead of Corallus consult Stejneger, Proc. U. S. nat. mus., 1902, 24, p. 184. 



Tropidophis melanura Schlegel. 

 Schlegel, Essai phys. serp., 1837, 2, p. 399. Boulenger, Cat. snakes Brit, mus., 1893, 1, p. 111. 



Stejneger (The Bahama Islands, 1905, p. 336) states that Tropidophis takes 

 precedence over Ungualia, since the former was based on Schlegel's Boa melanura 

 by Bibron in 1840, and thus antedates Gray's Ungualia by two years. 



This species is not uncommon, and I found it and heard of its regular occur- 

 rence in just one lurking place. A number of specimens were found in various 

 localities on Soledad estate, near Cienfuegos, Cuba, always hidden in the rolled 



/ faj.
