87. Shufeldt on the Osteology of Arctic and Sub-Arctic 

 Water-Birds. 



[Contributions to the Comparative Osteology of Arctic and Sub- Arctic 

 Water-Biids. Part II. By R. W. Shufeldt, M.D., C.M.Z.S. Plates 

 VII.-XI. Journ. Auat. and Physiology, xxiii. p. 165.] 



We have already noticed the first part of this instructive 

 memoir [supra, p. 252). In the second, which is illustrated 

 by five well-executed plates. Dr. Shufeldt treats specially 

 of the genus Uria, and points out its difl'erences from Alca 

 {cf. p. 183). 



88. Shufeldt on the Affinities of Aphriza. 



[On the Affinities of Aphriza virgata. By R. W. Shufeldt, M.D., 

 C.M.Z.S. Journ. of Morph. vol. ii. no. 2, 1888.] 



After a thorough examination of the various portions of 

 the skeleton of Aphriza, Dr. Shufeldt comes to the conclusion 

 that its supposed affinity with Haematopus is " by no means 

 a close one," the Oyster- catchers being entitled to form a 

 separate family of Limicolse, and that the sum total of its 

 skeletal characters bring it nearer the " typical large-sized 

 Tringeae with a four-notched sternum/' which it in " some 

 way connects with the Plovers.^' In fine, he proposes 

 to make Aphriza the sole representative of a family — 

 " Aphrizidse.^' 



89. Stejneger on a Kamtschatkan Woodpecker. 



[Diagnosis of the Kamtschatkan Three-toed Woodpecker {Picoides 

 albidior). By Leonhard Stejueger. Proc. U.S. Nat. Mus. 1888, p. 168.] 



Dr. Stejneger gives a diagnosis of Picoides albidior from 

 actual specimens, his previous characters (Bull. U.S. Nat. 

 JMus. no. 29, p. 321) having been based on some remarks of 

 Prof. Taczanowski.
