322 BARBOUR: ZOOGEOGRAPHY. 



Giinther's remarks, which I have quoted at length, apply far better to his 

 own attitude than to that of Garman; he has not shown at all that the range 

 of variation for M. dominica, which he had increased, touches the range for 

 that of M. agilis; while the average condition seen in the two categories of 

 individuals show how distinct they are. Invidious remarks regarding the sense 

 of specific discrimination are always dangerous. 



The types are M. C. Z., No. 6,049. 



Mabuya luciae Garman. 

 Garman, Bull. Essex inst., 1887, 19, p. 51. Boulenger, Proc. Zool. soc. London, 1891, p. 353. 



While considering this species as a variety of M. agilis, Boulenger admits 

 its subspecific rank. For the sake of consistency it is here considered a full 

 species; there being, however, obviously no question as to its origin from this 

 mainland species. It occurs upon St. Lucia. The types are M. C. Z., No. 6,046. 



Mabuya aenea Gray. 



Gray, Griffiths Cuvier's Animal kingdom, 1831, 9, Syn. reptil., p. 70. Garman, Bull. Essex inst., 

 1887, 19, p. 53. 



Garman considers specimens from St. Vincent, Grenada, and Trinidad dis- 

 tinct from M. aurata Schneider, from southern Central America to Brazil. 

 Boulenger (Proc. Zool. soc. London, 1891, p. 355) considers the Antillean speci- 

 mens referable to the latter species. If, when it becomes possible to study large 

 series, the characters which Garman points out are found to be constant, then 

 each of the two groups of individuals will be obviously entitled to hold specific 

 rank. 



Typhlops lumbricalis Linne. 



Linne, Syst. nat. ed. 10, 1758, 1, p. 228. Stejneger, Rept. U. S. nat. mus. for 1902, 1904, p. 6S4. 



This species extends from the region of the Guianas to both the Lesser and 

 Greater Antilles. It has long been known from many islands, among them 

 Dominica, St. Kitts, Antigua, the Virgin Islands, Guadeloupe, Martinique, 

 Mona, Porto Rico, Haiti, Jamaica, Cuba, and some of the Bahamas. In the 

 latter group it was first recorded by Cope (Proc. U. S. nat. mus., 1887, 10, p. 439) 

 from Great Abaco. In 1904 I found it again on the same island (Bull. M. C. Z., 

 1904, 46, p. 59). Curiously enough it was not found on either New Providence 

 or Andros Island until Rosen collected specimens at both localities (Rosen, 

 Lunds univ. arsskrift, 1911, 7, no. 5, p. 37). In Cuba and Jamaica its distribu- 

 tion is very wide, and I have found it at practically every station visited.
