33. Shiifeldt on the Screamers. 
[On the Osteology and Systematic Position of the Screamers {Palamedea : 
Chauna). Bj' R. W. Shufeldt. Amer. Xat. xxxv. pp. 455-461.] 
Dr. Shufeldt compares the principal points of structure of 
tlie 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 than 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. E. W. Shufeldt. 
Proc. Amer. Phil. Soc. xl. Xo. 165, 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 his former articles on the osteology of 
Geococcyx californiarius, 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 Crotophaginae, Centropodinee (represented 
by Geococcyx), and Cuculinae (represented by Coccyzus). 
Lastly, he treats of the aflSnities of the Cuckoos, and finds in 
them much less kinship to the Caprimulgi, Cypseli, Trogones, 
Trochili, and Pici than to the other Picarian forms. As 
opposed to Dr. Sharpe, he would place Diplopterus directly 
between the Ceutropodinse and Cuculinae. 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.
