assert that the female carries the ova in a kind of sac attached to her abdomen, 
until they are hatched. 
Dr. Giinther is of opinion that barely a third of the fish in the rivers and 
lakes of British Central Africa have as yet been made known in spite of our 
recent collections. He is probably right, and remarkable discoveries may yet 
await us, especially on Tanganyika, where numerous travellers have reported the 
existence of an exceedingly large fish which occasionally rushes at boats in a

threatening manner. Similar rumours of a very large fish in Nyasa are 
prevalent. Both Commander Cullen and Lieutenant-Commander Rhoades (of 
the Lake Nyasa gunboats) have reported curious circumstances tending to show 
that some very large fish or marine animal lives in Lake Nyasa, which amongst 
other things can bite off and carry away as a bait the brass log which is towed 
behind the vessels. It may not be more than a huge species of Bagrus , a 
Siluroid fish. Specimens of this creature have been already obtained which 
reached nearly six feet in length. 
The fish of Lake Nyasa, of Lake Chilwa and of the Upper Shire offer many 
examples which are excellent for eating, 1 with firm white flesh and few bones. 
1 A new genus of fish was obtained from Lake Nyasa —Engraulicypris pinguis. Dr. Giinther says, 
of this fish : "It might be preserved in a way similar to anchovies and would form a useful addition to- 
the food of the European community.” By the courtesy of the Zoological Society I am enabled to give 
an illustration of it here.
