Chrysichthys veJifer, sp. n. 



Depth of body 4| in the length, length of Lead fji. 

 Head 1^ times as long as broad, u[)per surface of postorbital 

 part slightly rugose ; occipital process rather narrow, 

 extending to the small interneural shield ; snout rounded, 

 1^ times as broad as long ; diameter of eye 4| in length of 

 head, If in length of snoat, and about twice in interorbital 

 width; mouth inferior, its width twice in length of head; 

 prseuiaxillary band of teeth nearly straight, 3^ times as long 

 as broad, length of band more than \ width of head ; vomero- 

 pterygoid teeth forming a narrow band interrupted in the 

 middle; nasal barbel about ^ diameter of eye ; maxillary 

 barbel i to | length of head ; outer mandibular barbel longer 

 than inner, about | length of head. Gill-rakers rather long, 

 13 on lower part of anterior arch. Dorsal I 6; about 1^ 

 times as distant from base of caudal as from end of snout ; 

 spine feebly granulated in front ; third soft ray longest, 

 reaching to root of caudal when laid back. Base of adipose 

 fin shorter than that of rayed dorsal, 2^ in its distance from 

 latter. Anal 11-12 ; 8 rays branched. Pectoral | length 

 of head, spine feebly granulated on outer border, strongly 

 serrated on inner. Caudal deeply forked, upper lobe longest. 

 Caudal peduncle IJ as long as deep. Grey above, silvery 

 vvhite beneath. 



A single specimen, 370 mm. in total length, from Bandama 

 Biver. 



Closely allied to C. 7iigrodigitatus, Lacep., from which it 

 may be distinguished by its broader snout, wider mouth, and 

 longer dorsal rays. 



Gephijroglanis lowei, sp. n. 

 Depth of body 5 times in the length, length of head 3|. 

 Head moderately depressed, granulated and striated above ; 

 opercle also slightly striated ; occipital process longer than 

 broad, in contact with the interneural shield ; snout about 

 as long as eye, which is oval and 3^ times in length of head ; 

 interorbital width a little more than ^ diameter of eye ; 

 nasid barbel minute ; maxillary barbel a little shorter than 

 head; outer mandibular barbel a little longer than inner, 

 and slightly more than J- length of head ; width of mouth 

 about i that of head ; priemaxillary band of teeth straight.
