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. 640-042, 3 figs.). 1 The figures illustrating 

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

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

 Brewster's and the Blue-footed Gannet" (The Auk, 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 Ills of the same year, in a 

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

 the fibula in the Sulidx (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^ Tr>f)4, making
