The face is short and broad. The front upper tubercular grinder square, 

 as long as broad ; the second rather broader than long, slightly narrowed on 

 the inner side, the last ovate, triangular, transverse. The teeth of the speci- 

 men were much worn ; the canines are conical, not grooved. 



This species is easily known from all the others of the genus hitherto 

 described, by the shortness of the tail and the height of the legs. I am not 

 certain that the tail of the specimen may not be imperfect, though there are no 

 appearances of its having been longer, and Mr. Hinds informs me that he believes 

 all the specimens seen were like the one here figured. It also differs from the 

 other kinds in the distribution of the black on the lower side of the head. 



" Several individuals were seen on the banks of the Sacramento, during the 

 expedition up that river, and were represented by the natives as very expert in 

 capturing the wild geese and ducks." — Ed.

Mr. Waterhouse has informed me, that he believes this is the same species as 

 that which I named, some years ago, in the Museum of the Zoological Society, 

 S. Douglasii. That animal has entirely passed from my mind ; and the collec- 

 tion of the Zoological Society having been packed up in a warehouse for the last 

 two years, and consequently quite inaccessible, I am not able to verify the accu- 

 racy of this suggestion.
