 aud distributiou are also considered at full length, and the 

 results of the author's observations testify to his careful 

 methods and the acuteness of his vision. He comes to the 

 conclusion that the habits in general are decidedly uniform 

 and seldom modified to an appreciable extent, a condition of 

 affairs which he evidently believes to hold in various species 

 of Passerine birds, if not elsewhere. 



Besides the Cliiffchaff, the Yellow-browed "Warbler is 

 described, but in this ease no mention is made of its habits : 

 a coloured plate is given of this species aud others of the 

 immature Sedge and Grasshopper Warblers, while maps are 

 added of the geographical distribution in summer and winter 

 of the Sedge and Aquatic Warblers. 



Under the head of distribution of the Chiffchaff, Mr. 

 Howard might have added that the bird is fairly common 

 in parts of West Ross-shire, and that a form — which he 

 would probably consider distinct — is well known in the 

 Canary Islands.

In our last number (above, p. 376) we gave an account of 

 the remarkable discoveries in Birds made by the Gunong Tahan 

 Expedition, extracted from a separate copy of Mr. Ogilvie- 

 Grant's article on the subject. We have now received a 

 complete copy of the Report, which, besides the special 

 articles on the Mammals, Birds, Fishes, &c., contains an 

 interesting narrative of the adventures of the expedition, 

 which left Taiping and Kuala Lumpur in May 1905 under 

 the command of Mr. L. Wray and Mr. H. C. Robinson for 

 the exploration of this celebrated mountain. Gunong Tahan 

 lies on the northern border of Pahang, where it rises to a 

 height of about 7200 feet above the sea-level. Although 

 several vigorous attempts had been made, no previous 

 explorers had succeeded in reaching the summit, which was 

 attained by Mr. Robinson (Mr. Wray having been compelled
