tions in established nomenclature. It is a golden rule^ in 

 our opinion, never to change a scientific name when it can 

 possibly be avoided. These, however, are but trifling criti- 

 cisms on the excellent piece of work turned out by the ener- 

 getic author of the present volume, which, looking to the 

 multifarious duties involved in the custody and arrangement 

 of the great National Collection of Birds, it is truly wonderful 

 that he should have found time to accomplish. 



55. Shufeldt on Birds^ Muscles useful in Classification. 



[A Review of tho Muscles used in the Classification of Birds. By R. 

 W. Shufeldt. Journ. Comp. Med. and Surg., Oct. 1887.] 



This seems to be a good general paper on the subject in 

 question, and, like all Dr. Shufeldt's writings, is excellently 

 illustrated. Whether the author is correct in his views of 

 the " dermo-tensor patagii^^ is, however, open to question. 

 See Dr. Stejneger^s remarks on this point (Science, x. p. 71), 

 noticed below. 



56. Stejneger on a Muscle of the Bird's Wing. 



[Pars propatagialis musculi cucullaris. By Leouhard Stejneger. 

 Science, vol. x. p. 70.] 



Dr. Stejneger maintains that Dr. Shufeldt's " dermo-tensor 

 patagii " of the bird^s wing, which he considers of" taxonomic 

 value '^ (Science, ix. p. 623), and to have been '^overlooked 

 by Garrod,^^ is by no means a new discovery, and not likely 

 to be useful in classification. See also ' The Auk,' v. p. 120. 



57. Stejeiieger on a tiew Thrush. 



. [Diagnosis of a new Species of Thrush (Tardus celcenops, sp. nov.) from 

 Japan. By Leonhard Stejneger. Science, vol. x. p. 108.] 



The American journal ' Science' for August 26th, 1887, 

 contains a description by Dr. Stejneger of a new Thrush, 

 Turdus celeenops, allied to T. chrysolaus, from the " Seven 

 Islands," south of the Bay of Tokio.
