above, lighter beneath. The specimens from Sabi Eiver have more 

 of a greyish tint and the scales (especially of the smallest) have a 

 bright red spot or bar in the centre, forming longitudinal lines on 

 the body. Fins dark ; in two of the specimens the caudal has a 

 white edge or border on inner margin of lobes. 



Three specimens, 400 mm., 370 mm., 177 mm. in length respec- 

 tively, from Sabi Eiver, Transvaal ; Major J. Stevenson Hamilton. 



One specimen, 394 mm. in length, from Karino, Crocodile Eiver, 

 Transvaal (A. T. Cooke). 



This species closely resembles L. coubie, from the Nile, but the 

 dorsal and pectoral fins are smaller and the caudal peduncle deeper ; 

 the colouring also differs. Major J. Stevenson Hamilton writes in 

 connection with the specimens sent by him from Sabi Eiver that the 

 fish clings " with its peculiar rubber-like mouth to rocks, usually at 

 the side of deep and rather swift streams. So far as I know it 

 will take no bait. I have plenty of opportunities of observing its 

 habits from the top of the railway bridge here, and the specimens 

 sent were secured by means of a rifle. I have never known them 

 caught either by white men or natives. The local name is 'sucker,' 

 significant of its habits."
