A specimen brought from the Webi Shebeli differs somewhat from the types which were collected on Kilima-njaro. Not only is the upper surface of the head granular, not covered by thin skin as in the types, but also the dorsal fins are more approximated. 11. ClTHARINUS GEOFFROII, CuV. This species extends from the Lower Nile to the Gambia and Niger. Two very young specimens from Lake Rudolf. 12. ALESTES RUPPELLII, Gthr. Hitherto known from the Upper Nile. One very young specimen from Lake Rudolf. 13. ALESTES AFFINIS, Gunth. P. Z. S. 1894, p. 90. Discovered by Dr. Gregory in the Tana River. Dr. Donaldson Smith brought home three specimens up to 15*5 cm. in length. a, b. From the Dawa River (25 & 28.2.95). c. From the Shebeli River (30.8.94). 14. DISTICHODUS RUDOLPHI, sp. n. D. 21-22. A. 14. L. lat. 100-108. L. transv. 18/24. The height of the body is contained 3| times in the total length (without caudal), the length of the head thrice or 3^ times. Snout rather pointed. Twenty-four teeth in the lower jaw. Silvery, greenish on the back, wdth nine blackish cross-bars and a large black praecaudal spot. The two specimens being very young, only 54 millim. long, it would not be safe to introduce more characters into the diagnosis of this species. They were obtained from Lake Rudolf. 15. LABEO GREGORII, Giinth. Proc. Zool. Soc. 1894, p. 90. Discovered by Dr. Gregory in the Tana River. Dr. Donaldson Smith brought from the Guaso Nyiro a dried specimen, 22 cm. long, which seems to belong to this species. Unfortunately, the form of the mouth is destroyed, owing to the mode of preservation. 16. BARBUS BYNNI, Forsk. A large specimen of this common Nilotic species, from the Shebeli River. Two very young specimens, 10 cm. long, from a stony brook running into the Erer R. (17 & 18.8.94), are probably the same species. • |
