14 Mk. G, A. BOULENGER ON A COLLECTION 
ae lat. 1. —- 
complete or nearly so, usually reaching base of caudal. Grey-brown above, with or 
without irregular darker spots, silvery below ; fins grey-brown, the ends of the ventral 
filaments white. 
Total length 92 millim. 
8 specimens from Kinyamkolo, and one from Mbity Rocks. 
This species is remarkable among its congeners from continental Africa for the low 
number of its dorsal spines combined with the large eye, the crescentic caudal, the 
extremely produced ventrals, and the upper lateral line extending on the caudal 
peduncle, 
Scales finely denticulate on the edge, 34-36 upper lateral line 
14. PARATILAPIA FURCIFER, sp. n. (Plate IV. fig. 1.) 
Teeth very small, in 5 series in both jaws, the outer largest and tipped with brown. 
Depth of body equal to length of head, 3 times in total length. Snout with curved 
upper profile, a little shorter than the eye, the diameter of which is 23 to 28 times in 
length of head and slightly exceeds interorbital width ; maxillary extending to below 
anterior border of eye; 2 or 3 series of scales on the cheek ; large scales on the 
opercle. Gill-rakers rather long, lanceolate, 15 or 16 on lower part of anterior arch. 
Dorsal XIII 13-14; spines increasing in length to the ninth, which measures a little 
less than 3 length of head; some of the soft rays produced, nearly as long as head. 
Pectoral a little longer than head. Ventral much produced, extending nearly to 
caudal. Anal HI 9; third spine longest, 3 length of head; middle soft rays 
produced, like the dorsals. Caudal deeply emarginate, crescentic, the rays at the 
angles produced. Caudal peduncle 13 as long as deep. Scales finely denticulate on 
the edge, 60-63 — pilates: ee upper lateral line nearly complete, extending on the 
caudal peduncle. Bluish above, white beneath ; a few ill-defined yellow streaks along 
the body; some yellow marblings on the postocular part of the head; fins white, 
with some yellow streaks on the dorsal and anal and between the ventral and caudal 
rays (according to a sketch by Mr. Moore). 
‘Total length 110 millim. 
‘Two specimens from Kinyamkolo. 
Closely allied to the preceding; distinguished by much smaller scales. 
15. PARATILAPIA LEPTOSOMA, sp. n. (Plate III. fig. 4.) 
Teeth small, in 3 series in the upper jaw, in 4 in the lower, outer largest. Depth 
of body 4 to 43 times in total length; length of head 3. Snout with straight upper 
profile, as long as or a little longer than the eye, the diameter of which is 34 to 3% 
times in length of head, and equals interorbital width ; maxillary extending to below 
anterior border of eye or not quite so far; 2 series of scales on the cheek; opercle
