in winter; " will carry their young on 1 their backs, even when flying from one lake to 

 another for two miles " (A. H. Whitehead). Dr. Atkins took several of these birds in 

 March and April. I have taken them, or seen them, in nearly all seasons of the year. 



6-9-{842). Urinator arcticus (Linn.). BLACK-THROATED LOON; BLACK-THROATED 

 DIVER. 



Exceedingly rare; Lake Michigan; winter; "occasionally on Lake Michigan" 

 (Gibbs' Birds of Mich.); "Upper Peninsula" (A. H. Boies); "Keweenaw Point" (Knee- 

 land). 

 7-ll-(844). Urinator In mine (Gunn.), RED-THROATED LOON; RED-THROATED DIVER. 



Rather common; "throughout the state, have taken several alive on snow in winter" 

 (A. H Boies); winter; migrates north in spring; found on lakes and rivers in all parts 

 of the state; "almost a yearly visitor- in Kalamazoo Co." (Dr. M. Gibbs); "Keweenaw 

 Point" (Kneeland); "found breeding at Green Bay, Wis." (Prof. Ludwig Kumlein); 

 "breeds in Arctic regions" (Dr. A. K. Fisher). 



FAMILY ALCID^E. THE AUKS. 



These curious water birds are specially marine and it is doubtful if they belong to 

 our fauna; if ever seen here they are undoubtedly wanderers. 



GENUS FRATERCULA BRISS. 



8-18-(864). Fratercula arctica (Linn.). COMMON PUFFIN. 



"Rare straggler" (Gibbs' Birds of Michigan); "have never heard of one on Lake 

 Superior" (C. S. Osborn). I think this of doubtful occurrence in Michigan. 



GENUS SYNTHL1BORAMPHUS BRANDT. 



9-21-(8(J4). Synthliboramphus autiqims (Gmel). ANCIENT MURRELET; BLACK- 

 THROATED MURRELET. 



Prof. Ludwig Kumlein writes me that he has taken one specimen at Lake Kosh- 

 konong, Wis., and one on Lake Michigan. One was shot late in October by Rev. G. E. 

 Gordon on Lake Koshkonong, Wis. (Geo, B. Sennett in The Auk for January, 1884) 1 

 Coues says one straggler taken in Wisconsin. 



GENUS CEPPHUS PALL. 



10-27-(871). Cepphus grylle (Linn.). BLACK GUILLEMOT. 



"Not rare in Upper Peninsula, occasional seasons" (Dr. M. Gibbs); "may occur as 

 a rare straggler" (Prof. Ludwig Kumlein): "very rare even as an accidental visitor" 

 (C. S. Osborn). 



GENUS URIA BRISS. 



1 l-80-(874). Uria troile (Linn.). MURRE. 



"Occasionally taken on Lake Superior" (Gibbs' Birds of Michigan). I think this a 

 doubtful Michigan bird; "so do I also all the other Alcidae" (Robt. Ridgway). 



GENUS ALCA. LINN. 



J2-32-(877). Alca torda Linn. RAZOR-BILLED AUK. 



" Irregular visitor to Northern Peninsula" (Gibbs' Birds of Michigan); "I have
