25. Shufeldt on the Osteology of the Tubinares and Stega- 

 nopodes. 



[Observations upon the Osteology of the Orders Tubinares and Stega- 

 nopodes. By Dr. P. W. Shufeldt. Proc. U.S. Nat. Mus. xi. p. 253.] 



In this article Dr. Shufeldt describes and illustrates the 

 skeletons of Oceanodroma furcata and Fuhnarus glacialis 

 rodgersi, and summarises the points in which they differ. In 

 like manner he describes the skeleton of Diomedea albatrus, 

 and states his agreement with Forbes's views (Scient. Mem. 

 p. 434) as to relationship of the Tubinares. He then turns 

 to the Steganopodes, and discusses at full length the osteology 

 of Sula bassana and a skull of Pelecanus fuscus. 



26. Shufeldt on the Osteology of the Herons. 

 [Osteological Studies of the Subfamily Ardeinee. By R. W. Shufeldt, 



M.D., C.M.Z.S. Journ. Comp. Med. & Surg., July 1889.] 



This memoir is chiefly devoted to a full account of the 

 osteological characters of Ardea herodias, which is well 

 chosen as a type of the true Ardeina:. Some general 

 observations are prefaced, in the course of which the author 

 well remarks that many of the nine genera into which recent 

 authors have divided the North-American Ardeinse are super- 

 fluous, and that they may be safely reduced to two — Ardea 

 and Nycticorax. 



27. Sousa on new Collections from Angola. 



[Aves de Angola de explora^o do Sr. Jose de Auchieta. Por Jose 

 Augusto de Sousa. Jorn. Sci. Math. Phys. e Nat. Lisboa, 2 a ser. no. 2, 

 1889, p. 113.] 



M. de Sousa, Conservator of the Zoological Section of the 

 Lisbon Museum, gives an account of two Angolan collec- 

 tions recently received from Sr. Anchieta. The first, from 

 Catumbella, contains examples of 36 species, amongst which 

 are two specimens of an A^gialitis, allied to JE. venusta and 

 JE. mechorsi, but presenting some differential features, also 

 the first example of Hydrochelidon nigra received from An- 

 gola. The second collection, from Quissanga, in Benguela, 

 contains specimens of 29 species.
