Fossil Birds in the Marsh Collection of Yale University 69 



a new extinct genus of Cormorants, suggested by Coues (MSS. 1898) 

 to contain Phalacrocorax perspicillatus; for there are no good generic 

 characters in the skeleton of the last-named species which would 

 justify the creation of a genus. (Compared with No. 17041. Coll. 

 U. S. Nat. Mus., P. perspicillatus:) (See Fig. 44.) 



Tympanuchus lulli sp. nov. 

 {Plate XII, Fig. 90.) 



Holotype. Cat. No. 911, Peabody Musemn, Yale University. Homerstown, 

 New Jersey. Post-Pliocene. (Evidently a later deposit in the marl, which is 

 Cretaceous.) J. G. Meirs, collector. 



This is an imperfect left humerus of an adult species of Grouse. A 

 large part of the head of the bone has been fractured ofif; otherwise 

 it is in good state of preservation. I have carefully compared the 

 specimen with the humeri of all of our larger species of existing grouse, 

 and I find that it falls squarely in the genus Tympanuchus, having 

 belonged to a bird apparently somewhat larger than Tympanuchus 

 americanus. ^ 



I take pleasure in naming this extinct species of Prairie Chicken for 

 Doctor Richard Swann Lull, of the Department of Palaeontology of 

 Yale University (Peabody Museum), in recognition of his valuable 

 contributions to the study of Extinct Reptilia and other vertebrates. 



Uria .\ffinis (Marsh.) 

 {Plate VIII, Fig. 60.) 



Catarractes affinis Marsh, Amer. Jouni. Sci., ser. 3, IV, 1872, 259. 

 Holotype. No Cat. Number. Academy of Natural Sciences of Philadelphia. 

 Bangor, Maine. Pleistocene. A. C. Hamlin, collector. 



This type specimen is perfect in all particulars. It is smooth, shiny 

 and free from any matrix. The color is of a deep ochre, with greenish 

 white stainings at the extremities. 



It is slightly longer than a humerus of Uria lomvia in the Collection 

 of the United States National Museum (No. 18068), and in no other 

 respects differs from it in its characters.
