Very sliglit, if any, characters are given for these new 

 generic terms ; it appears to be considered quite enough to 

 indicate the typical species. 



On the whole we cannot consider Mr. Mathews' 'Reference 

 List ' to be a satisfactory piece of work, although it must 

 have caused liim raucli time and much trouble. His mode 

 of treatment of the Australian Crows has already been 

 criticized (see Bull. B.O.C. 1912, p. 70), and bis proposal to 

 create such a crowd of subspecies is not likely to be accepted 

 by bis fellow-workers in Australia, though it may meet the 

 approval of some of the more ardent members of the " new 

 school. '^ 



70. Nelson on two new Nun-birds. 



[Descriptions of two new species of Nnu-birds from Panama. By E. W, 

 Nelson. Smiths. Misc. Coll. vol. xxxvi. No. 37. Washington, 1912.] 



A single example of each of these supposed new species 

 of Monusa was obtained by Mr. E. A. Goldman while workinj^ 

 on the Smithsonian Biological Survey of Panama during 

 tlie winter of 1911. Mr. Nelson has named them M.fidelis 

 and M. siinilis. 



77. NicoUon Birds observed in the Zoological Gardens, Giza. 



[Wild Birds of the Giza Gardens, 1898-1911. Bv Michael J. Nicoll. 

 Pp. 22.] 



This is a second edition of the List of the Wild Birds 

 tbat liave been observed in the Zoological Gardens at Giza, 

 which seems to be a paradise for the featbered race, or 

 perhaps we may say a place of refuge fur rare species. 

 Altliough hardly more than fifty acres in extent the Giza 

 Gardens, which are on the left bank of the Nile opposite to 

 the city of Cairo, seem to be peculiarly attractive to birds 

 of all descriptions, and Mr. Nicoll has added a considerable 

 number to his li&r, of bird-visitors since the publication of 

 his first edition. It now embraces 200 species, of which 

 187 belong to the Avifauna of Egypt, and 13 are foreigners, 

 presumably escaped from captivity. Seventeen species are 

 known to have bred within the Gardens.
