THE OSTEOLOGY OF THE STEGANOPODES. 



By R. W. Shufeldt, M.D. 



At the present writing it is a little over nineteen years ago since I first paid any 

 attention to the osteology of the steganopodous birds. My initial paper upon this 

 subject was a brief one devoted to the osteology of Phalacrocorax bicristatus {Science, 

 Vol. 2, No. 41, Nov. 16, 1883, pp. 640-642, 3 figs.).^ The figures illustrating 

 that paper have since been used in text-books on ornithology and zoology to 

 some extent. As will be observed in the body of the present memoir, five years 

 later I published another contribution to this subject, entitled "Observations upon 

 the Osteology of the Orders Tubinares and Steganopodes" (Proc. U. S. Nat. Mus., 

 Vol. XI., 1888, pp. 253-315, 43 figs, in text); and also in January, 1889, " Notes on 

 Brewster's and the Blue-footed Gannet" {The AuJc, Vol. VI., No. 1, p. 67). What 

 I have done in the matter of fossil birds of this suborder, will be chiefly found in 

 my memoir, "A Study of the Fossil Avifauna of the Equus Beds of the Oregon 

 Desert" {Jour. Acad. Nat. Sci. Phila., Vol. XL, Pis. XV.-XVII, (4to), Phila., Oct., 1892, 

 pp. 389-425), and a number of abstracts of the same, subsequently published else- 

 where, as in The American Naturalist, and The Auk: In 1894, in the Proceedings of 

 the Zoological Society of London, I published a brief paper " On the Affinities of 

 the Steganopodes" (Feb. 20, pp. 160-162), and in the Ihis of the same year, in a 

 paper entitled " On Cases of Complete Fibulse in Existing Birds," made a study of 

 the fibula in the Sulidse (Vol. VI., No. 23, London, July, 1894, Art. XXIX., pp. 361- 

 366, figs. 1, 2). The Auk also published a paper of mine in October, 1894, making

 No. 63, pp. 474, 475, Apr. 18, 1884.
