This addition raises the number of species of fishes now known 

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

 number 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. 



EHLiMPHOLEOX BRACHTURrS, Gthr. P. Z. S. 1892, p. 557. 



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

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

 differ from the opposite sex. 



Ehampholeox 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. 



Ehampholeo hoeftgeri, Pfeffer, Zool. Ergebn. Eeise Stuhlmann, 

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

 species. 



Psammophylax variabilis, Gthr. P. Z. S. 1892, p. 557. 

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

 examples of 2Ius doUchurus in their stomachs. 



Dasypeltis scabra, L. 



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

 the specific distinctness of D. picdmarum. 



' Obtained by the Rev. J. A. Williams. 



* Caught in the Upper Shire Eiver. 



' Thia species has a distinct, unserrated, osseous spine, much stronger Ihnn 

 the rays and stronger than is figured by Peters, who had one specimen only 

 from the Lower Zambesi.
