Chubb' s Birds of British Guiana. 



[Tlie Birds of British. Guiana, based on the collection of Frederick 

 Vasavour McConnell. Bj Charles Chubb. Vol. ii. pp. xcvi+615; 

 8 photographic plates, 10 coloured plates, 214 text-figs. London 

 (Quaritch), 1921. 8vo.] 



The first volume of this work, containing the non-Passerine 

 birds, was published in 1916 (see Ibis, 1916, p. .505). The 

 second volume, completing the work and containing the 

 description of the Passerine birds, is now before us, and 

 is a worthy monument to the industry and skill of 

 Mr. Charles Chubb and to the memory of the late 

 Mr. F. V. McConnell, an enthusiastic observer and collector 

 of British Guiana Birds. 



The introduction contains an itinerary of over 70 pages of 

 the second journey undertaken by Mr. McConnell to Horainia 

 in 1898, in which he was again accompanied by Mr. J. J. 

 Quelch, late of the Georgetown Museum. The itinerai'y was 

 drawn up by Mr. Quelch and contains a lively account of the 

 journey to Roraima, and also of the condition of the plateau 

 which forms the top. The avifauna was insignificant, and 

 apparently the only bird obtained there was a Song Sparrow, 

 Brachyspiza macconnelli, the type of which was collected by 

 Mr. McConnell himself in 1898. The itinerary is illustrated 

 by two photographs of the summit-plateau and several more 

 of the Indians whom they came across during the trip. 

 The bulk of the volume is taken up with the detailed 

 description of the species, 366 in number, all of which 

 appear to have been most carefully drawn up. It is very 

 noticeable how little field-work has been done in Britisli 

 Guiana. Breeding-season, nest, eggs, and habits are fol- 

 lowed in a very large proportion of cases by " unknown " 

 or '^ unrecorded.^' There is undoubtedly a great field for
