On examining the hares from the region usually said to be 
inhabited by “ Lepus brasiliensis,” I find that they belong to 
three different forms—the present one, the largest, from 
Rio Jordéo and Lagoa Santa, a middle one from Paraguay 
obtained by Mr. Foster, and a very small one from Rio 
Janeiro. Of the last-named, a fully adult specimen from 
Porto Real, near Rezende, Rio, has a skull only just 
47 millim. in basilar length, with small narrow nasals, and 
with its postorbital processes firmly welded to the skull 
posteriorly. 
The original Lepus brasiliensis of Linneus and L. tapeti 
of Pallas were both primarily founded on Maregrave’s 
Tapeti*; and since even at that date Rio Janeiro was the 
chief settlement in this part of Brazil, it would seem best to 
consider the Rio animal as representing that species. Mavrc- 
grave’s description is, of course, not worth much; but as to 
size, his ‘‘dupla magnitudine gliris” suggests the very 
smallest conceivable hare. I therefore propose to call the 
Rio hare L. brasiliensis and to give new names to the other 
two. ‘The Paraguayan one is described below. 
Lund and Winge’s Lepus brasiliensis is the larger Minas 
species.

This series is of much interest, as showing the considerable 
amount of colour-variation to be found in this group in 
specimens from one locality. In their general pattern of 
coloration five of the specimens may be called normal—that 
is to say, with the head, nape, fore limbs, fore back in the 
central line, and hind feet light, and the hind back dark with 
two broad shoulder-straps passing forwards across the humerus. 
But the dark may be deep black to the roots of the fur, with 
the underfur also black, or may vary to yellowish white with 
black tips, the underfur also whitish. Again, the light 
colour may vary from pale yellowish white to a strong reddish 
tone. 
One specimen alone, no. 739, differs markedly from the 
rest, and agrees precisely with Cope’s “ JZyrmecophaga bi- 
vittata straminea’”’ +, to which it is clearly assignable. But
