sampled, gave nothing but iron, and traces only of copper, just suffi- 

 cient to colour the ammoniacal solution. 



III. — Bunlcabarri Ores. 



A compact and tough, massive, and fibrous hornblende rock ; with 

 promising nests of pyrites (as to size) interspersed, but on examina- 

 tion it was found to be exactly the same as the foregoing No. II. 

 affording a mere trace of copper only. 



A Monograph of the Indian species of Phtlloscopus and its imme- 

 diate affines. — By Edward Bltth. 



There is no group of birds more difficult to the student of Indian 

 Ornithology, than the very extensive series of small Bee-fins, or 

 " Warblers," known to the French as Bouillots, and in parts of 

 England by the name of Betty chaps. It is exemplified in Europe by 

 four well known species j* and as an avis rarissima in Europe, the 

 common Indian Motacilla proregulus, Pallas {Begulus modestus, 

 Gould), which strictly appertains to the series under review, has 



* 1. Phylloscopus sibilatrix ; Motacilla sibilatrix, L. : Sylvia sylvicola, 

 Latham. Type of Sibilatrix, Kaup. 



2. Ph. Bonelli ; Sylvia Bonelli, Vieillot : S. Nattereri, Temminck. 



3. Ph. trochijlus ; Motacilla trochilus, L. : Sylvia fitis, Bechstein : also, 

 according to M. Degland, S\ icterina, Temminck (nee Vieillot) ; S. flaviventris, 

 Vieillot; &. anyuslicauda, Gerbe ; and S. tamariocis, Crespigny. 



4. Ph. rufus ; Curruca rufa, Brisson : Sylvia collybita, Vieillot ; S. loquax, 

 Herbert ; and by the older British ornithologists erroneously assigned to Motacilla 

 hippolais, L. 



In addition to these four, in N. Africa, Dr. Riippell describes — 



Ph. umbiiovirens ; Sylvia umbrovirens, Riippell (described but not figured in 



his Neuen Wirbelthieren, Voyel, p. 112). From Abyssinia. 



Ph. brevicaudatus ; Sylvia brevicaudata, Riippell, Atlas, t. 35, From 



Kordofan. 



Another that will probably have to be added to the European fauna is 



Ph. brevirostris ; Sylvia brevirostris, Strickland, P. Z. S. 1836, p. 98. 



Procured at Smyrna. Differs from Ph. rufus in its greater size, and from Ph. 



trochilus " in the shortness of the beak, and the dark colour of the legs." 



Lastly, two species are briefly described in Dr. Horsfield's Catalogue of Javanese 



birds, Trans. Lin, Soc. xiii. 156 ; neither of which can we identify with Indian 



species : viz.
