1-3. Zegi. — Degen. (Types.) 



4. Juju E. — Zaphiro. 



As stated above (p. 196), one of the specimens is remarkable in having three 

 pharyngeal teeth, instead of two, on each side in the outer series. A second specimen 

 examined showed the normal number of pharyngeal teeth : 2, 3, 5 — 5, 3, 2. 



Three specimens were obtained by Mr. Degen from Lake Tsana at Zegi, May 18th 

 and 19th, 1902. A fourth specimen, from the Juju River (alt. 2000 feet), flowing 

 into the Didessa River, a southern tributary of the Blue Nile, forms part of Mr. Zaphiro's 

 collection. 



This Barbus is distinguished from B. brevibarbis by the more elongate form, the 

 shorter head, the thinner lips, and the longer spine of the dorsal fin.
