126. Trouessart on Zoological Geographrj. 

 [La G(5ographie Zoologique, par le Dr. E. L. Trouessart. Paris, 1890.] 



Dr. Trouessart has kindly sent us a copy of his ' Geographic 

 Zoologique/ which, although published several years ago, 

 had escaped our attention. Like Mr. Beddard's volume 

 above noticed, it is a useful compendium, with much valuable 

 information condensed into a small compass. Dr. Troues- 

 sart, we are glad to see, adheres mainly to the six great 

 Regions of Sclater and Wallace, though he wishes to add 

 two to their number — an Arctic and an Antarctic Region *. 

 Of these we need only say that they are in our opinion 

 " quantites negligeables,^^ though there is more ground for 

 the recognition of the latter than for that of the former. 

 We will venture to add a few remarks on what we deem to be 

 slight inaccuracies in the portions of Dr. Trouessart's manual 

 which relate to birds. 



The Penguin of the Galapagos [op. cit. p. 43) is Spheni^cus 

 '^ mendiculus/' not '' mendicatus/' and the Penguin of the 

 Cape {Spheniscus demersus) is quite different from that of 

 the Falkland Islands {S. magellanicus). See "Birds'' of the 

 'Challenger' Expedition, p. 125, pis. xxvii. & xxviii. 



The Lesser Sheath -bill {Chionis minor) differs from its 

 congener (C. alba) not only in size {of. op. cit. p. 45), but in 

 its black bill and other particulars. There are at present 

 examples of both the species living in the Zoological Society's 

 Gardens. On the west coast of North America at least 

 (contrary to what our author says, p. 264), Humming-birds 

 go far north of 40° N. lat., Selasphorus rufus being a regular 

 summer visitor at Sitka (57° 3' N. lat.). In the east of 



* The six Regions of Sclater are stated (p. 13) to have been founded 

 in 1835 in a ' Treatise on the Geography and Classification of Animals 

 in Lardner's Cabinet Cyclopedia.' This is altogether a mistake. They 

 were founded in June 1857, in a paper read before the Linnean Society 

 of London, entitled " On the General Geographical Distribution of the 

 Members of the Class Aves." See Journ. Linn. Soc. vol. ii. p. 130.
