head and 1§ in tlie interocular wiiltli ; the wiilch of tlie moutli 

 equals about half that of th'j head ; two pairs of barbels, tho 

 first I the diameter of the eye, the second § or f. S:n ill 

 pearl-like excrescences on the sides and top of the heal. 

 Dorsal III 9; third ray feeble, smooth; lotii^est ray | thi 

 length of ihe head. Anal II G; longest ray f or | len;i;th of 

 head, not reaching the root of the caudal. Pectoral po.atel, 

 a little shorter than the head, not reaching the ventral, whic'i 

 is inserted under the first rays of the dorsal. Caudal forked. 

 Caudal peduncle nearly twice as long as deep. Scales longi- 

 tudinally striated, o5-36 ?j, 2^ between the lateral line and 

 the root of the ventral. ISteel-grey above, silvery beneath ; 

 an indistinct darker lateral band. 

 Total length 120 millim. 



Both these species are related to the Moroccan Barhus 

 described by Dr. Giintheras li. Fritschii and 13. Uuthschildi ; 

 but as they have a perfectly trenchant edge to the lower jaw, 

 covered with a thin horny layer, they strictly belong to 

 Capoe'a, whatever the value of tliis systematic division may 

 be. They differ besides froai both the above-:iamed B irbas 

 in the more feeble third dorsal ray and the shorter barbels. 



The new fishes were obtained, together with examples of 

 Barbus callensis, C. & V., and B. nasas, Gthr., in tiie Atlas 

 Mountains, in a stream running into the Wad N'fys at a 

 place called Tsigadir-el-hor ; the water in which they live is 

 slightly salt. They have been presented to the British 

 Museum by Mr. E. G. B. Meade-Waldo. 



XXIV. — On Mammals from Cochabamha, Bolivia, and the 

 Uegion north of that place. By Oldfield ThomaS, F.K.S. 



Mr. Peury 0. Simons, who has been collecting mammals all 

 down the Andean region for the last three years, and whose 

 success is evidenced by the many novelties described in the 

 'Annals,' made in March to July 1901 a collection (I) at and 

 near Cochabamba, Bolivia, (2) on the high paramos north of 

 that town, and (3) on the Amazonian lowlands of Yungas, 

 just north of these again. This collection contains so largj a 

 proportion of novelties and is from so little known a country 

 that 1 have thought it advisable to give a list of all tlie 

 mammals sent, instead of only picking out the novelties for 

 description as heretofore.
