Ptycho hamphus aleuticus, Brandt, 1837. 



Mergulus cassinii, Gambel, Proc. Acad. Philad. II, 1845, 266. — 1b. J. A. N. S. 2d series, II, 1850 ; pi. vi. 



Sp. Ch — Small. General form short and heavy ; bill conical, pointed ; wing moderate ; tail short ; legs and feet moderate ; 

 tarsi compressed. Bill brownish black, with a conspicuous spot of yellow at the base of the under mandible. Head above and 

 entire upper parts dark fuliginous, nearly black on the back and top of the head, tinged with ashy on the rump. Throat and 

 sides of the neck light ashy ; other under parts white ; a longitudinal stripe on the sides from the breast to the tibia dark ashy 

 brown ; under tail coverts white ; feet dark. 



Total length about 8 inches ; wing, 4 J ; tail, 1 j inches. 



JSab. — Western and northwestern coast of America ; California, (Dr. Gambel.) 



This quite peculiar little bird is well figured in the Journal of the Philadelphia Academy, as 

 above cited, and is occasionally brought in collections from the western coasts of the United 

 States. It was first added to our fauna by the late Dr. William Gambel, as above, but is 

 undoubtedly the bird described by Pallas in Zoographia Rosso-Asiatica.
