1911] 8warth: Alaska Expedition of 1909. 31 



Lunda cirrhata (Pallas). Tufted Puffin. 



Seen only on Warren Channel, where, on May 23, several 

 were observed feeding in the tide rips in the vicinity of "Whale- 

 head Island. A single specimen secured here at this time 

 (no. 9917, female) is in a peculiar stage of plumage, considering 

 the time of year. It is a bird of the previous year at least, but 

 evidently was not breeding. It was extremely emaciated, sug- 

 gesting the possibility of its diseased condition causing some 

 irregularity in the molt. 



In appearance this bird is as follows: Above glossy black. 

 Sides of head and neck, throat, upper breast, and sides, slaty 

 black, this area rather sharply defined against the lighter 

 colored ventral surface. Lower breast and abdomen white, the 

 feathers tipped with slate gray, a few scattering ones tipped 

 with dull black. Flanks and crissum, slate gray. Lower tail 

 coverts black tipped. On the side of the head there is a line of 

 exceedingly narrow, plume-like feathers (no longer than the 

 rest of the plumage however), dirty whitish in color, beginning 

 just over the eye, and extending backward 35 mm. The bill, in 

 size and shape, is practically like the illustration of the juvenal 

 in winter figured by Stejneger (1885, plate II, fig. 3). 



As seen from the above description, the general appearance 

 of this bird (except for the bill) is much like that of some 

 examples of CerorMnca monocerata. 



Cerorhinca monocerata (Pallas). Rhinoceros Auklet. 



This species does not seem to venture farther into the 

 sheltered channels than the swell of the open sea extends; we 

 saw it only along the coasts of the more exposed western 

 islands. Two were seen off Cape Decision, Kuiu Island, on May 

 18, a number were observed in Warren Channel on May 19 and 

 23, and they were quite common along the west coast of Dall 

 Island, June 4 to 6. 



Three specimens were secured (nos. 9903-9905), all in full 

 breeding plumage.
