554 ME. Q. A. BOULENG-ER 0~S A COLLECTION 



keel, granulate above, striated below, not extending beyond vertical of occipito-nuchal 

 shield. Skin slightly villose on the sides of the body. Dorsal I 7 ; spine strong, 

 curved, nearly as long as head, striated, smooth in front, with a few very feeble and 

 indistinct serrse behind ; a filament terminates the spine. Adipose dorsal 4 times as 

 long as deep, twice and -| as long as its distance from the rayed dorsal. Anal IV 7. 

 Pectoral spine striated and strongly serrated on both sides, nearly as long as head. 

 Ventral not reaching anal. Caudal deeply forked, upper lobe longer. Grey above, 

 white beneath, closely dotted with black on the body as well as on the fins. 



Total length 260 millim. Grows to 520 millim. according to Dr. Cunnington. 



A single specimen from Lofu. Native name : Kiyegeyege. 



Allied to S. multipunctatus Blgr., zambesensis Peters, and punctulatus Gthr. 

 Distinguished by the almost total absence of serration on the back of the dorsal 

 fin-spine, the presence of strong serrse on the outer border of the pectoral spine, and 

 the villosities on the body. The eye is much smaller than in S. multipunctatus. 



This species is also nearly related to S. schall Bl. Schn., in which the upper surface 

 of the snout is smooth and the outer edge of the pectoral spine more feebly serrated.

CyPEIKODONTIDX 



25. Haplochilus pumilus, sp. n. (Plate XXXII. fig. 4.) 



Depth of body 3-f to 4^ times in total length, length of head %\ to 4 times. Upper 

 surface of head flat ; snout shorter than the eye, the diameter of which is 3 times in 

 length of head ; lower jaw projecting beyond upper ; interoibital space f length of 

 head. Dorsal 10-11, originating nearer to root of caudal than to occiput; posterior 

 rays longest, ^ to f length of head. Anal 14-15, originating at equal distance from 

 eye and from root of caudal ; posterior rays longest, about as long as dorsals. Pectoral 

 •§ length of head, reaching beyond base of ventral. Caudal rounded, nearly as long 

 as head. Caudal peduncle once and ■§• as long as deep. Scales with the concentric 

 stria? very indistinct, 27 to 29 in a longitudinal series, 7 in a transverse series.
