154 NEW YORK ZOOLOGICAL SOCIETY. 



Mustela atratata actuosa?j (Osgood). ALASKAN 

 MARTEN. 



While none were seen, they are captured along Knik River. I 

 saw skins that were brought from the Matanuska River country, 

 all of which were very pale. 



Lutreolavisoiieiierg-iiiiiemis, (Bangs). PACIFIC MINK. 



One was seen while we were on the way to our base camp, some 

 twenty miles from the mouth of the Knik River. It was at the 

 mouth of a muskrat's hole in a bank. 



Lutra canadensis paciflca, {Rhoads). NORTHERN 

 LAND OTTER. 

 Two were observed in a small stream about twenty miles from 

 the mouth of Knik River, and their slides were frequently seen. 

 One of my Indians said otter often kill muskrats, and eat them. 



Plioca fasciata, (Zimm.). RIBBON SEAL. 



While none were seen by me, the following entry from my 

 journal is of interest : " Mr. J. B. Carold, of Juneau, says he was 

 told by a reliable hunter that a spotted seal inhabited Iliamna Lake, 

 a large fresh-water lake on the western side of the Alaskan 

 Peninsula." Since this note was made, Mr. J. H. Kidder, of Bos- 

 ton, who spent the summer in Alaska, secured a skin of one of 

 these seals, which proved to be of the species named above. Evi- 

 dently the seals had traveled up the outlet of the lake, and, finding 

 an abundance of fish, remained there. 



Plioca vituliua, (Linn.). HARBOR SEAL. 



Quite common about Tyonek, where several were seen. The 

 natives frequently shoot them. On May 6th we saw one near the 

 head of Knik Arm. 



BIRDS. 



Colymbus holboellii, (Reinh.). HOLBCELL'S GREBE. 



A pair of these grebes were seen. May nth, in a lake back of 

 our camp, some twenty miles from the mouth of Knik River. 



Colymbus auritus, (Linn.). HORNED GREBE. 

 Three seen, May 3d, at the mouth of Knik River.
