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.
