These lie has expanded and enlarged into the volume now 

 before us, in which he attempts to bring together observa- 

 tions old and new on that period of the life-history of 

 animals between birth and maturity. Only a small propor- 

 tion of the work deals directly with birds, but there are 

 chapters on the duration of youth, the colours and patterns, 

 and brood-care in birds, all of which may be read with 

 profit by ornithologists, though no very startling new 

 hypotheses are propounded. 



A word must be said for the coloured illustrations, which 

 certainly form a remarkable departure from the usual style. 

 They were originally painted by Mr. Yarrow Jones on 

 Japanese silk, and have been reproduced with great skill. 

 Although in no sense would they be useful in a systematic 

 treatise, they have a character and individuality which im- 

 presses itself at once on our imagination, and may perhaps 

 reveal characteristics not easily described in words or 

 diagrams.

In the first paper the authors discuss a collection of birds 

 made by Mr. A. Meek on the Kumusi River — which lies at 

 the extreme north-eastern corner of New Guinea, close to 

 the German boundary — in 1907. Examples of 119 species 

 were obtained, of which Pitta mackloti oblita, Machari- 

 rhijnchus flaviventer novus, Coracina papuensis meekiana, 

 Ptilotis analoga vicina, and Finarolestes megarhynchus 

 superfluus are characterized as new subspecies. 



The second paper contains another list of birds made by 

 the same collector at Collingwood, being also on the north- 

 eastern coast of New Guinea but further to the east, about 

 halfway between the German frontier and the eastern
