104 ORIGIN, ETC., OF THE FAUNA. 
of such genera as Loncheres, Dasyprocta, and Dasypus. Furthermore, the restriction of 
Capromys to Cuba, Jamaica, and some of the islands towards Central America and 
the kinship between this genus and living and fossil South American genera suggest 
a connection between Central America and those islands of the Greater Antilles. 
But this conclusion cannot at present be reconciled with the absence of other Central 
American forms, both of northern and southern origin, from the Greater Antilles. 
If, on the other hand, the Hystricomorphs passed into South America from Africa or 
South Europe, and if the West Indies formed part of the transatlantic land, the 
faunistic resemblance between Haiti, Cuba, Jamaica, and South America supplied by 
Capromys and Plagiodontia may be due to the derivation of the fauna from a common 
African source. ‘The relationship between Solenodon of Cuba and Haiti and the 
Afro-Mascarene Centetide has an interesting bearing on this question, although, if 
Micropternodus be, as alleged, a Selenodont Insectivore, Cuba and Haiti must 
presumably have been connected with some part of North America.
