Indus, and the rivers of tlie Punjab. I have shot on the Sutlej, 

 the BeaSj the Chenah, and tlie Indus, almost from their source 

 to the sea ; but I have never succeeded, though of late years 

 I have been specially on the look-out for this species, in 

 seeing or securing" a specimen. This bird is very much larger 

 than our Indian species, and has the dusky baud on the chest 

 very much more conspicuous.

Dr. Sclater in his valuable monograph of the C^/pselida, first 

 pointed out that " there are two South" African specimens of a swift 

 in the Leyden Museum, labelled " Oj/pselm harhatus" which differ 

 from the European examples principally in their lighter color 

 above, particularly on the secondaries and scapulars -, in the 

 white feathers of the gular patch presenting a narrow black cen- 

 tral line, and in the feathers of the lower back, belly, and under 

 wing-coverts being narrowly margined with white. Two examples 

 from Natal, collected by Mr. Ayres, are similar. It is possible 

 that this form may be entitled to rank as a species to which 

 Temminck's MS. name may be applied. But it would be 

 desirable to obtain more skins for comparison, particularly ex- 

 amples from other parts of South Africa.''^ In 1867 loc. cit., Mr. 

 Tristram argued that this Souths African representative of 

 Ct/pselas apm,^\io\\[(i\)e recognized as distinct under Temminck^s 

 manuscript name, on the ground that all known specimens from 

 South Africa agreed in the peculiarities pointed out by Sclater. 

 Mr. Gurney loc. cit., appears to have accepted this conclusion. 

 Gray however united harhatus with apus in his " Hand list," 

 and Dr. R. Finsch in his careful paper on the birds of N. E. 

 Abj^ssinia, and the Bogos country, demonstrated to my mind 

 conclusively that harhatus is nothing but the young of apus. 

 Professor Blasius'' opinion which he quotes is peculiarly to the 

 j)oint. He says "your specimens are nothing more than the young 

 of C. apus, and I cannot distinguish them from others collected 

 in our country. I possess also such young ones from Nubia as 

 well as old sp)ecime?is from the Cape and Nubiaj Avhich agree in
