PALiEOSYOPS LEIDY, AND ITS ALLIES. 3(i5 
referred to L. laticeps, so that I shall describe this tarsus as ])elonging to this sjKTies. 
The form of the pes is long and narrow ; its length corresponds almost exactly with 
that of the Indian Tapir, but it is narrower. Compared with the f«x)t ol /'. tmiior 
we see considerable difference in size, as the pes in that sjyecies is much 
broader and heavier than in laticeps. The metapodials are much lighter than 
in P. minoi', and closely resemble in their proportions those of the Tapir. The 
middle metatarsal is considerably larger than the lateral metapodials, in this char- 
acter also approaching the foot of the Tapir.

Calcaneum.— The calcaneum of L. laticeps is long and narrow, with a much 
compressed tuberosity which has a concavity at the extremity sulKlividing this js.r- 
tion of the bone and resembling in form that of the ctdcaneum of Hyracodon. 1 la- 
neck of the calcaneum is deep, and where it joins the articular portmn, it is com- 
pressed and continued into the narrow anterior part. The artic.dar surtace is narn.w 
and deep, especially so in this species. The ectal facet is broad transversely, and the 
anterior prolongation is not so conspicuous as in Palccosyops paludosus. I he 
sustentaculum is very long and narrow and is placed close to the ectal facet. 1 he 
distal portion of both calcanea which I refer to this species aredamagc-«l, so that it is
