of many species that winter in the plains. Of the total 

 number of 336 species which the list contains, 317 were 

 found in Kohat, the remaining 19 were met with only in 

 the Kurram Valley. Considered together, therefore, the 

 single paper will be found to be of greater scientific value 

 than if the two districts had been separately treated, and 

 Mr. Whitehead deserves much credit for the excellent piece 

 of work which he has accomplished. 



II. — Preface. 

 By C. H. T. Whitehead. 



-Major Magrath does not take any credit for his own work. 

 Before I even started he had made a fair list of the birds of 

 Kohat, and it was his enthusiasm that infected me. All that 

 I have done is to somewhat amplify this list and add a little 

 to the notes. The paper should have been Avritten by him, 

 but he insisted on my doing so, and has now most kindly 

 gone carefully through it, making many necessary corrections 

 and alterations and entirely rewriting the account of the 

 Bulbuls of the genus Molpastes, the hybrid forms of which 

 he was first to observe in Kohat. 



Much interesting information was kindly contributed by 

 Mr. D. Donald, C.I.E., the Political Officer and Commandant 

 of the Border Military Police and Samana Rifles, which his 

 long residence in Kohat (some 18 years), his frequent tours 

 in the district, the interest he takes in birds generally, and 

 in the Accipitrines in particular, and his great reputation as 

 a falconer, render of especial value. 



Specimens of most of the Passerine and of a large number 

 of the remaining birds included in this paper were shot 

 and carefully compared with Oates and Blanford's excellent 

 descriptions, measurements and points of difference, if any, 

 being always recorded, but only in the case of their not 

 corresponding or of their being of special interest were skins 

 made, for time did not permit of more. These skins are now 

 in the Britisli Museum and are those I'cferred to in the paper. 

 Amongst them will be found melanistic varieties of several 

 species (Lanius lahtora, Passer domeslicus, Anthus similis,
