224 BARBOUR: ZOOGEOGRAPHY. 



Cuba, it is almost certain that this record is based on a specimen from some other 

 locality, probably Mexico. A number of the molluscs which d'Orbigny de- 

 scribed from Cuba in the same work have been shown to have been Mexican and 

 n t Cuban. 



Natrix anoscopa (Cope). 



Cope, Proc. Acad. nat. sci. Phila., 1861, p. 299; Proc. U. S. nat. mus., 1892, 14, p. 673. Botjlengeh, 

 Cat. snakes Brit, mus., 1893, 1, p. 242. 



A Cuban species, the only Antillean representative of its genus. Cope 

 compares it with N. cyclopion and N. rhombifera. Dr. Stejneger is inclined to 

 believe that Cope had an African species. It is probably some species which 

 by mistake got marked with an incorrect locality label. The evidence that 

 Gundlach ever really found a species of Natrix in Cuba is very far from con- 

 vincing. There is no Natrix of any species in the Museo Gundlach of the 

 Instituto de Segunda Ensefianza in Havana. 



Kinosternon baurii Garman. 

 Carman, Bull. Essex inst., 1892, 23, p. 141. Siebenrock, Zool. jahrb. Suppl. 1909, 10, p. 442. 



One of the types (M. C. Z., No. 4,050) of this species is said to have come 

 from Cuba. It was mentioned at an earlier date by Garman; and was said to 

 have been sent to the Museum, with much other Cuban material, by Filipe Poey 

 (Proc. Amer. philos. soc, 1887, 24, p. 286). This is the only member of the 

 family Cinosternidae which has ever been suggested to occur in the West Indies. 

 On a visit to Washington, April, 1912, I saw in the United States national mu- 

 seum a specimen of Gerrhonotus! which was also said to have been sent from Cuba 

 by Filipe Poey. Of course both these specimens may be victims of misplaced 

 labels. 



ZOOGEOGRAPHY. 



Instead of discussing the geographical distribution of the genera or species, 

 it is more convenient to take up the fauna of each island or group of islands 

 having a homogeneous biota; and then in a general survey, to draw some general 

 conclusions regarding the main features of origin and dispersal of the fauna. 



Cuba. 



This island first claims attention because of many peculiar characteristics. 

 It shows a far more intimate relationship with both North America and Central
