I was fortunate enough to secure five specimens of this rare and re- 

 markable rabbit. Heretofore but one specimen of this species has been

brought before the scientific world, and it (ISTo. 4263) is now on exhibi- 

 tion in the Smithsonian Institution. It was collected in the Wind Eiver 

 Mountains by Dr. Hayden in the month of June, 1860, and was described 

 by him in the American JSTatnralist, (vol. lii, Ko. 3, May, 1S69.) Un- 

 fortunately the sex of this specimen was not determined. 



One very curious fact relating to Lepus hairdii is that all the males 

 have teats and take part in suckling the young. I say all the males, 

 because four out of the five specimens procured were adult males, and 

 all had large teats full of milk, and the hair around the nipple was wet 

 and stuck to it, showing that they were then nursing their young.
