1. Merula javanica (Horsf.). 



Mount Arjuno at 8000 and 8300 feet. Wings in three adult males 125, 125, 

 128 mm. See Biittikofer's notes on this bird in Notes Ley den Museum, XV. 

 p. 107 (1893). I have here retained, for the sake of convenience, the generic 

 name " Merula " for this bird, though I do not now believe that there is any 

 scientific foundation for that genus. 



2. Cettia montana (Horsf.). 



Differs from C. oreophila Sharpe from Kina Balu in Borneo in having a 

 shorter tarsus and being less brown above. Differs from C. seebohmi Grant of 

 Luzon in having a much more olive and less rufous tail, wings, and forehead, from 

 C. cantillans and its allies in being smaller and more of a dark olive colour. 



It is dark brownish olive above from the forehead to the tip of the tail. 

 Below whitish, with a brown wash along the sides of the body and across the middle 

 of the breast. Wing-quills deep brownish olive, with narrow brown margins to the 

 outer webs, and whitish borders to the inner webs. Under wing-coverts white. In 

 the rather full and broad wing the fourth, fifth, sixth, and seventh primaries are 

 almost equal and longest. Wing : <$ 53, $ 49 mm. ; tail : c? 57 ( $ not measurable 

 on account of moult) ; tarsus 21 ; culmen 14 mm. 



One cT from an elevation of 7500, one ? from between 9000 and 10,000 feet, on 

 Mount Arjuno, East Java, in January 1896. 



This is the Sylvia montana of Horsfield. It is quite omitted from the Catalogue 

 of Birds, and the only mention I can find of it is that it is quoted, without explana- 

 tion, as Cettia montana (Horsf.) in Whitehead's Exploration of Kina Balu, p. 258. 

 The type of Horsfield's S. montana is in the British Museum, and it is evidently the 

 same as the bird from Arjuno, so I think it the best course to accept Horsfield's 

 name, to avoid synonyms, though one would be fully justified to do away with 

 Horsfield's name altogether, and to doubt the identity of the skin in the British 

 Museum with Horsfield's type, as the description of the underparts (" olivacea- 

 testacea") is totally wrong. This is what Mr. Grant wrote me about the species, 

 and I have, besides, examined the specimens myself: 



Cettia montana (Horsf.). 

 Sylvia montana Horsfield, Trans. Linn. Soc. XIII. p. 156 (1821). 



Although no mention of this species is made in the Catalogue of Birds, 

 Vol. V., there is, in addition to Horsfield's type, a second example in the British 

 Museum collected by Wallace in 1861 and marked "$. West Java." In the type 

 the shape of the wing is as follows : first primary quill much shorter than the 

 second ; second much shorter than the third, which is about equal to the tenth; 

 sixth slightly the longest. In Wallace's specimen the wings and tail are in moult, 

 but the shape of the wing appears to be similar to the above. In both specimens 

 the whitish eye-brow stripe, commencing above the lores and extending above the 

 ear-coverts, is well marked ; the middle of the throat and breast pale whitish buff, 

 inclining to whitish on the belly; the sides of the chest and breast, the sides, flanks, 

 and under tap -coverts brownish buff; the upper parts, including the wings and tail, 

 dark browi ish olive ; and the cheeks and sides of the throat are similar, but the basal
