250 SORKX. 



Specimen is in fair eDndition; some hair has fallen from the ])aek. The skull 

 has not lu-en removed (and the skull of a j)aratyi>e ia the one probably figured), 

 but the lips have bi'en cut loose and the left cheek split so that all the teeth may 

 be seen. 



Baird had seven specimens from four different localities. The description is 

 based upon nos. 'A&2 and 1(577. As the latter is (i<,Mired on |il. 27 it is here taken 

 as the type.

All parts of the skin are i)resent, but it is poorly maile uj) uiid not in good 

 condition. The skull is badly deaneil and more or less broken about the cra- 

 nium, andthe right half of the mandible is missing. 



9f>7. Skin (no skull). Same data as the above, with the addition that 

 it was collected on June 10, 1855. Catalogued November, 1855. 



The skin of the second cotype is even worse than that of the first. It evi- 

 dently contained a skull, which has been removed and lost. 



Baird lists four specimens by nuud)er, the above two and two from Steila- 

 coom, Washington. From his remarks on page 15 it is clear that tlu'iirst two form 

 the basis of his description. On pi. 26 one of the Oregon sj)ecimens is figured 

 (see explanation of plates, p. 742).
