Recently published Ornithological Works. 497 



is in Linnaeus's collection of books in the Library of the 

 Linnean Society of London. This copy of the sale-list is 

 accompanied by a separately paged portion called 

 " Adumbratiunculae/' in which 38 new species of Birds 

 arc described in Latin. These new names were attributed 

 by Mr. Sherborn in the ' Index Animalium ' to Vroeg, but 

 it has been lately shewn that the great Russian naturalist 

 Pallas (then of the age of 23) was the author of them. 

 Mr. Sherborn now reprints the " Adumbratiunculse." They 

 are ; of course, of much interest, but those who (like ourselves) 

 begin their binomial nomenclature with the 12th edition of 

 the 'Systema Naturse ' (1760) will not adopt them as valid, 

 even if they could be certainly referred to determinable 

 species (see under " Richmond " above, p. 490). 



86. Shufeldt on Classification. 



[An Arrangement of the Families and the higher Groups of Birds. By 

 I!. \V. Shufeldt. Amer. Nat. xxxviii. pp. 838-857, 6 figs.] 



This contribution by Dr. Shufeldt to the study of taxonomy 

 carries us through a series of Orders, Supersuborders, Sub- 

 orders, and Superfamilies to the Families, after the author's 

 well-known style. It is based on Palaeontology, Comparative 

 Morphology, Oology, and Nidification, not forgetting I'terylo- 

 graphy, but does not differ strikingly from such classifications 

 as that of Fiirbringer, except that Dr. Shufeldt denies that 

 birds can be divided into two subclasses. 



87. Stone on Birds from Mount Sanhedrin, California. 



[On a Collection of Birds and Mammals from Mount Sanhedrin, 

 California. By Witmer Stone. With Field-notes by A. S. Bunnell. 

 Proc. R. Acad. Sc. Phil., July 1904 (p. 'u6).] 



The collection of Birds was made by Mr. Bunnell during 

 two trips in the months of May, June, and July 1897 and 

 in 1899, to Lierlie's Ranch, alt. 2100 feet, while Mount 

 Sanhedrin rises to about 5000. It contains examples of 

 56 species, all of which may be regarded as breeding there, 

 while 33 others are added from Mr. Bunnell's observation. 

 Calypte anna and Selasphorus alleni were the only two
