Chiloglanis Batesii. 



Body somewhat depressed in front, compressed behind, its 

 deptli 5 to 6 times in the total length. Head depressed, once 

 and ^ as long- as broad, its length 3 times in the total length. 

 Eye directed npwards, in second half of head, its diameter 5 

 limes in length of head and equal to interorbital width, which 

 exceeds the distance between the eye and the posterior 

 nostril ; prajmaxillary teeth in two large oval groups, well 

 separated on the middle line, forming 3 or 4 transverse 

 series ; a group of 8 to 12 slender mandibular teeth ; maxillary 

 barbel as long as . eye, lower labial barbels shorter still. 

 Dorsal I 5; spine not serrated, '^ to \ length of head. 

 Adipose low, its base barely ^ its distance from the rayed 

 dorsal. Anal III 5. Pectoral spine not serrated, about ^ 

 length of head. Ventral extei\ding beyond origin of anal. 

 Caudal deeply forked, upper lobe moi»e or less produced. 

 Caudal peduncle twice as long as dee]). Yellowish brown 

 above, with large dark brown marblings forming more or 

 less regular cross-bands ; a black bar at the base of the

 Mr. S. L. Hinds in the Kenya district of East Africa; 

 differing in the slightly larger eye, the more numerous 

 mandibular teeth, and the longer ventral fin. 



Ilaplochihis macrurus. 



Depth of body equal to length of head, ?i\ to 4 times in 

 total length. Upper surface of head flat ; snout much shorter 

 than the eye, the diameter of which is about 3 times in length 

 of head ; lower jaw projecting beyond upper; interorbital 

 space f to ^ length of head. Dorsal 7-8, rounded, originating 

 nearer to root of caudal than to occiput; longest rays 3 to f 

 length of head. Anal 12-14, originating at equal distance 

 from eye and from root of caudal ; longest rays as long as 

 head. Pectoral nearly f length of head, reaching beyond 

 base of ventral. Caudal tin rounded, longer than head.
