 number (36 or 37) of scales in the lateral line. 



This little fish, described by de Joannis in 1835, from a single specimen obtained by 

 him at Luxor, which appears to be lost, has been a puzzle to naturalists, as no one, 

 previous to Mr. Loat's expedition, seems to have come across it again. Dr. Giinther, 

 in 1896, thought he recognized the fish among the collection brought home from the 

 Ogowe by the late Miss Kingsley, but, as I have shown, his Barilius bibie is quite 

 different and 1 have proposed for it the name of Barilius Mngsleyw. 



Mr. Loat obtained his first specimen on the 9th January, 1900, at Assuan, where the 

 fish was said to be not uncommon in the summer ; a second specimen was obtained at 

 the same place on the 30th September, 1900, and a third near Kermeh in April of the 

 same year; others were found at, Luxor and between Luxor and Assuan, between 

 September and November of the same year ; whilst it occurred in such abundance at 

 Omdurman in May 1901 that Mr. Loat was able to preserve about 1500 specimens. 

 C. bibie is also found in the White Nile and the Bahr-el-Gebel, Mr. Loat having brought, 

 home specimens from Kaka, Lake No, and Gondokoro. Quite recently, Dr. F. Werner 

 has obtained specimens near Kalioub, in the Delta region. Finally, I have to record 

 its presence in Somaliland, whence it has been received by the Paris Museum.

Called "libie" (<u^u) in Upper Egypt, a name also applied to Barilius niloticus; 

 " bibiea " at Luxor. 



Some of the females obtained at Omdurman at the end of May were full of eggs 

 ready to be deposited. These eggs are of relatively large size, measuring 1 millimetre 

 in diameter. 



Among the specimens from Gondokoro, not a few bear the black spots which are 

 frequent in some of our small European Cyprinids and which are caused by a parasite *, 

 apparently a Diplostomum, the local irritation of which causes an aggregation of the 

 black pigment-cells.
