33. Shufeldt on the Screamers, 



[On the Osteology and Systematic Position of tlio Screamers {Palamedea : 

 Chauna). By R. W. Shufeldt. Amer. Nat. xxxv. pp. 455-461.] 



I)r. Shufeldt compares the principal points of structure of 

 the Screamer, the Swan, and the Turkey in a tabular form, 

 and concludes that, taken as a whole, the Anserine characters 

 of the Screamer are more evident tlian those of the other 

 forms. " The Screamers should he placed near the Anseres, 

 but apart and in an independent group." Most other 

 modern authorities are of exactly the same opinion. 



34. Shufeldt on the Coccyges. 



[The Osteology of the Cuckoos [Coccyges]. By Dr. R. W. Shufeldt. 

 Proc. Amer. Phil. Soc. xl. No. 105, pis. i., ii.] 



In the present paper Dr. Shufeldt treats the Cuckoos of 

 the United States after his usual fashion in writing of such 

 groups. His own work on the same subject and the 

 writings of other authors having been discussed, he reprints, 

 with additions, one of liis former articles on the osteology of 

 Geococcyx californianus, which is followed by a note on its 

 young, accounts of the osteology of Crotophaga and Coccyzus 

 (including the young of the latter), and a synopsis of the 

 osteology of the Crotophaginse, Centropodinse (represented 

 by Geococcyx), and Cuculinai (represented by Coccyzus). 

 Lastly, he treats of the affinities of the Cuckoos, and finds in 

 them much less kinship to theCaprimulgi, Cypseli, Trogones, 

 Trochili, and Pici than to the other Picarian forms. As 

 opposed to Dr. Sharpc, he would place Biplopterus directly 

 between the Centropodinae and Cuculinse. In Geococcyx he 

 finds the skull to differ from that described by Huxley, the 

 pelvis to resemble that of Porzana Carolina, and the tibio- 

 tarsal shaft of comparatively large size in the young.
