brought before the scientific world, and it (No. 4263) is now on exhibi- 

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

 Mountains by Dr. Hay den in the month of June, 1800, and was described 

 by him in the American jSTaturalist, (vol. iii, No. 3, May, 1869.) Un- 

 foi'tunately the sex of this si)ecimen was uot deteruiined. 



One very curious fa{;t relatiug to Lepm hairdii is that all the males 

 have teats and talce part in suckling the youug. I say all the males, 

 because four out of tlie five speciuiens procured were adult males, and 

 all had hirge teats full of milk, and the hair ai'onnd tiu' niijole was wet 

 and stuck to it, showing that they were then uurbing their youug.
