I am inclined to refer to the same species, although the black spots on the sides are 

 either absent or very faintly indicated. Three of them, obtained in the Eovuma River, 

 80 miles from the coast, were received from Sir J. Kirk in 1864, whilst the fourth, from 

 Lake Rudolf, forms part of the collection made by Dr. Donaldson Smith. The largest 

 measures 45 millimetres. Sq. 24-26 |f. The Lake Rudolf specimen has been recorded 

 by Dr. Giinther* as: " Barlus sp. A very young specimen, 5 cm. long, from Lake 

 Rudolf, cannot be specifically determined." It is a female, full of ova. 



Specimens were also obtained in Lake Abaia by Baron Maurice de Rothschild in 

 1905.
