PARISOMA PLUMBEUM. 219 



his travels in South Africa, met with the species in Swaziland, 

 and shot a male and female in July, which are now in the 

 British Museum. In the Zambesi district Mr. Boyd Alexander 

 obtained a specimen in the vicinity of the Kafue river, and 

 Mr. Alexander Whyte one on the Zomba plateau of the Shire 

 highlands. 



A very doubtfully good subspecies, P. catoleucum, Reichen., 

 has been described from one of Dr. Fiilleborn's specimens from 

 Undis to the north of Lake Nyasa, and apparently a rather 

 better marked subspecies, P. orientalis, Reichen., inhabits 

 Kibwezi in South Ukamba. From the description of P. cato- 

 leucum, it resembles P. orientalis in having the under tail- 

 coverts white, and P. plumbeum (Hartl.) in the pale colouring 

 of the upper parts. It is stretching a point in the original 

 description when it is said to be smaller than P. plumbeum. I 

 much doubt if these subspecific forms will be recognisable 

 when our series of specimens are more complete. In my key 

 I have entered P. catoleucum and P. orientalis as subspecies of 

 P. plumbeum, because they all apparently agree both in their 

 measurements and style of colouring, and differ only in a mere 

 shade. Not having seen a typical specimen of P. catoleucum 

 I cannot say which of the other two it most resembles, but 

 judging by the description it comes remarkably near to P. 

 orientalis, so it may have the chance of being called P. plum- 

 beum orientalis catoleucum. The type of P. orientalis which is 

 in the Berlin Museum was procured by Mr. Oskar Neumann at 

 Kibwezi, in South Ukamba. The only other specimens known 

 to me are three males and two females collected at the same 

 locality by Mr. Jackson, in March, 1892. 



At first sight Mr. Jackson's examples appear to be very 

 clean, freshly moulted specimens of P. plumbeum (Hartl.) ; but 

 their chief character lies in the under tail-coverts being white 

 with scarcely any trace of colour. P. orientalis, Reichen., is so
