SHUFELDT : OSTEOLOGY OF THE STEGANOPODES 



167 



In their essential characters, the quadrates, the pterygoids, the palatines, and 

 the maxillo-palatines agree with what we found above in Anhinga. Phalacrocorax 

 also has a small supramaxillary, or as Parker called it, a " post-maxillary," and 

 according to him it is large in P. carbo, and small in P. graculus. 



FIG. 13. Palatal region of a young Pluilacrocurax urile, showing the maxillo-palatine of the right side. 



FIG. 14. Dorsal aspect of anterior part of the cranium of a young I'halacrocoraj; urile, showing the absence of a 

 fronto-nasal hinge. 



FIG. 15. Lateral aspect of beak of a young Phalacrovorax urile, showing the open condition of the nostril. All 

 three figures drawn by Mr. F. A. Lucas from specimen No. 12732 of the collections of the II. S. Nat. Museum, and 

 enlarged hy means of the camera lucida. 



Regarding the maxillo-palatines and related bones in the skull of a Cormorant, 

 it seems that ornithotomists do not quite agree as to the exact sutural boundaries, 

 and it seems that Mr. W. P. Pycraft, of the British Museum, some time ago printed 

 an article on the osteology of certain steganopodes, in which he was at variance with 

 anatomists upon this point. Desiring the opinion of Mr. Lucas upon this point, he 

 has kindly furnished me with the following remarks, and illustrated them with 

 some drawings, which latter are here reproduced as Figs. 13, 14 and 15. In his 

 communication he says: "Some difference of opinion exists as to just what portions 

 of the maxillaries represent the maxillo-palatines, and while I do not like to differ 

 with my friend Mr. Pycraft for fear I be on the wrong side, yet, after carefully con- 

 sidering the subject, the conclusion is forced upon one that the posterior extensions 

 of the maxillaries are the maxillo-palatines."
