This addition raises the number of species of fishes now known 

 from Lake Nyasa and the Shire Eiver to thirty-three, but the 

 n amber actuallv' inhabiting these waters may be safely estimated 

 at thrice that figure at the very least. 



I subjoin descriptions of the new species, with some notes on 

 others previously known. 



Ehampholeo' brachyueus, Gthr. P. Z. S. 1892, p. 557. 



This species was described in the first report from a female ; 

 3Ir. Johnston has now sent a male, which does not essentially 

 dilier from the opposite sex. 



EhampuoleojST platyceps, Gthr. P. Z. S. 1892, p. 556. 



This species was also described in the first report from a female, 

 which, besides, was mutilated. The male now sent shows that the 

 tail is really as short as represented (in outline) in the figure given 

 of this species. The male has a very small skinny lobe at the end 

 of the snout, and about six distant and inconspicuous tubercular 

 projections along the median ridge of the back. It was obtained 

 at Tshiromo. 



Rhampholeo hoettrjeri, Pfeffer, Zool. Ergebn. Eeise Stuhlmann, 

 1893 ; Eept. p. 8, Taf. i. tigs. 6 and 7, may prove to be the same 

 species. 



PSAMMOPUYLAX VARIABIEIS, Gthr. P. Z. S. 1892, p. 557. 

 This Snake must be very useful as a destroyer of mice ; two had 

 examples of ^Ins duJichirus in their stomachs. 



Dasypeltis scabra, L. 



Common. The series of scales vary from 23 to 27. I doubt 

 the specific distinctness of D. pahnaram.
