GEOLOGICAL SURVEY OF THE TERRITORIES. 



As we found no females, we thought this might be an hermaphroditic 

 form ; so Dr. Josiah Curtis and myself dissected a large male — No. 44, 

 (1241:^5, 11098) — which we found to contain the usual genital organs of 

 the male, but no uterus, ovaries, or other female organs. I dissected 

 another old male — l^o. 46, (12413, 11099) — with the same result. I re- 

 gret exceedingly that I was unable to procure a female specimen; but, 

 from the limited non)ber of specimens examined, I should infer that 

 both sexes take part in suckling their young. 



I jjublish the following letter from Dr. Curtis, verifying the above 

 statements: 



Washington, D. C, February 20, 1873. 

 Dear Sir: When upon that part of oui' explorations last summer which embraced 

 the region about the hea.d-waters of the Snake River, I saw several specimens of the 

 rabbit (Lejjws ftairdii, Haydeu) which you had secured, and the adults gave external 

 signs of having been suckled, but gave every other evideueo of being true males. 



To satisfy you, as well as myself, beyond a doubt upon this point, I very carefully 

 dissected one unmistakably-marked specimen, and found conclusive evidence of its 

 ;having been recently and for some time suckled. Milk was abundant in its udders. 

 It, however, possessed no other organs characteristic of the female sex, but it did have 

 all the male organs complete and well developed. 

 Yours, respectfully, 



JOSIAH CURTIS,
