On the Origin of West Indian Bird Life, by J. M. Cuapman. Con- 
clusions from study of bird (and mammal) life were (1) distinctness 
zoologically of Lesser from Greater Antilles; (2) independence of islands 
from mainland since the appearance of the present fauna; (3) original 
connection of Indes to Central America by way of Jamaica, Central 
America at this time; an archipelago created by passage leading from Pacific 
to Carribean sea; (4) the older faunal forms of the Indes represent sur- 
vivors of the insular tertiary species; (5) the newer forms are immigrants 
and become differentiated under need conditions of living. 
H. F. Ossorn reported the discovery in the Miocene of South Dakota 
of a horned artiodactyl represented by male and female skulls and com- 
plete fore and hind feet. The female skull is comparatively hornless and 
prooves to be identical with Protoceras celer Marsa. The male 
skull exhibits no less than five protuberances upon each side, or ten 
altogether. Two of these upon the frontals and sides of the maxillaries are 
very small; the parietal, supraorbital and maxillary protuberances are 
very prominent and had, apparently, a dermal covering as in the Giraffe. 
There are four toes in front and two behind as in the early Tragu- 
lidae. The types were found by D*' J. L. Worrman, and are in the 
recent collections of the Am. Mus. of Nat. Hist.
