^The description is taken from a specimen given to the Museum by Mr. Francis Gay. April 17, igoo (B. P. B. M. No. 9307). During the 

 interval between the writing and the publication of the description Mr. Henshaw has described a specimen taken by Mr. M. Newell (Brother 

 Matthias), which seems to be the same as the Kauai specimen in the Museum. I therefore withdraw my matiuicript name (with due apology 

 to Mr. Gay) in favor of Mr. Henshaw's published name. See Auk (1900), Vol. XVil., p. 246. The locality of Mr. Henshaw's type is at fault. 

 It doubtless is a misprint and should be Waihu Valley, Island of Maui, in the place of "Waihu Valley. Island of Mani." 



9 Female in the colledlion taken by Mr. A. F. Judd on Kauai during the winter of 1892-93, from which the above measurements 

 were taken. 



^°Dr. Schauinsland, in his list of the birds of Laysan Island, adds O. fiiligiriosa (Gm.) to the Hawaiian fauna. It can be easily dis- 

 tinguished from O. cyyptoleucura by its larger size (length .10, wing 7.50) and having the upper tail coverts the same color as the back. 



^^ .Since the preparation of the above I have a list of the birds obtained on Laysan by Dr. Schauinsland, Dire<ftor Stadt. Museum, Bremen, 

 in which he gives Phalacrocorax plagicns. Pall. The species may be identified by the foUowinp;: The upper mandible terminating in a dis- 

 tinct hook ; tarsus longer than the hind toe a-nd claw; with a small, scarcely noticeable gular sac ; bill slender with outline straight ; tail much 

 longer than the wing, graduated and composed of twelve feathers ; culmen less than 2.50 ; feathers on the lower jaw projedting forward be. 

 yond the anterior angle of the eye ; head and neck rich glossy silky violet black : more purplish towards the head, becoming silky dark 

 green on the lower parts. Breeding plumage: Neck and rump ornamented with very narrow white feathers, i'oung: Uniform brownish 

 dusky. Length 25.00-29.00, wing 9.50-10.60. //ab. Coast of Asia from Kamschatka to South China, from Alaska to South Mexico(?). (Hawaiian 

 Islands, Laysan. — Br. Schauinsland.)
