426 On some Fishes from the Shari River. XL. — a some Fishes from the Shari River, with Descriptions of Two new Species. By G. A. Boulenger, F.R.S. (Published by permission of the Trustees of the British Museum.) M. A. BAUDON, Administrator of the Ubanghi-Sliari Colony, French Equatorial Africa, has kindly sent me, for the British Museum, a little series of small fishes from the Shari River, containing examples of two species not included in Dr. Pelle-griu's excellent book ' Les Poissons du Bassin du Tchad,' and of. two others that are undescribed. The genus Barbus, as yet unknown from that Basin, is represented by two species : B. pleuropholis, Blgr., pre-viously recorded from the Congo, the Aruwimi, and the Uelle, and B. baudoni, sp. n. The Cyprinodonts belong to two species : Uaplochi/us acuticaudatus, Pellegr., and H. hutereaui, Blgr., the latter recently discovered in the Uelle. Other species are Anabas petherici, Gthr., Tilapia melanopleura, A. Dum., Eleotris nana, Blgr. *, and Ander-sonia brevior, sp. n., belonging to a very remarkable genus of Siluridse, of which a single species was known : A. leptura, Blgr., from the Upper Nile and the Bahr-el-Gebel. Barbus baudoni. Depth of body equal to length of head, 3§ to 3§ times in total length. Snout rounded, shorter than the eye, which is 2f times in length of head and equals interorbital width ; mouth small, terminal, with thin lips ; no barbels. Dorsal III 8, equally distant from centre of eye and from caudal, border very feebly concave ; last simple ray not enlarged, not serrated, a little shorter than head. Anal III 5, not reaching caudal. Pectoral about f length of head, not reaching ventral ; base of latter below middle of dorsal. Caudal peduncle 1^ times as long as deep. Scales radiately striated, 23-24^, 2 between lateral line and ventral, 8 round caudal peduncle. Yellowish brown above, silvery beneath ; a band of crowded black dots from the gill-opening to the base of the caudal ; on this band, three round black spots, the first just in front of the dorsal, the second just behind the latter, * These specimens connect the Nile fish with E. uellensis, Blgr., which is probably not entitled to stand as a distinct species.
