OF FISHES FROM LAKE TANGANYIKA. 13 
This species, which I have much pleasure in naming after the distinguished zoologist 
© ny . ‘ y “O° 1 f 
of Hamburg, Dr. G. Pfeffer, who has much contributed to our knowledge of East 
African ichthyology, is nearest allied to P. intermedia Gthr., from Nyassa. 
12. PARATILAPIA MACROPS, sp. n. (Plate III. fig. 2.) 
Teeth small, in 3 series in each jaw, forming a narrow band, outer largest. Depth 
of body three times in total length ; length of head 23 to 3. Snout with straight upper 
profile, a little shorter than the eye, the diameter of which is 2; times in length of 
head and 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 
short, 11 on lower part of anterior arch. Dorsal XVI 10-12; spines increasing in 
length to the sixth, which measures a little less than } length of head and equals 
longest soft rays. Pectoral as long as head. Ventral extending a little beyond origin 
of anal. Anal III 6-7; third spine longest, a little shorter than longest dorsal. 
Caudal with crescentic emargination. Caudal peduncle as long as deep. Scales very 
finely denticulate on the edge, 33-34 os lat. 1. a upper lateral line complete, 
extending to base of caudal. Pale brownish above, silvery beneath; a series of five 
indistinct dark blotches on each side of the body; spinous dorsal edged with brown 
above. 
Total length 70 millim. 
Two specimens from Kinyamkolo, and one from Mbity Rocks. 
Closely allied to the preceding species; distinguished by the larger eye, the complete 
upper lateral line, the longer pectoral, and the more strongly emarginate caudal. 
Connects the preceding species with the following, which represents a more aberrant 
type. 
13. PARATILAPIA VENTRALIS, sp. n. (Plate III. fig. 3.) 
Teeth very small, in 2 series in both jaws, the outer larger and tipped with brown. 
Depth of body 22 to 3 times in total length, length of head 3. Snout with curved 
upper profile, a little shorter than the eye, the diameter of which is 23 to 2? times 
in length of head and exceeds interorbital width ; maxillary extending to below 
anterior fourth of eye; 2 or 3 series of scales on the cheek; large scales on the 
opercle. Gill-rakers rather long, lanceolate, 17 to 19 on lower part of anterior arch. 
Dorsal XII-XIII 13-14; spines increasing in length to the eighth or ninth, which 
measures nearly 4 length of head and ? or % longest soft rays. Pectoral a little longer 
than head. Ventral much produced, extending far beyond the origin of the anal, 
especially in the males, in which it may reach the end of the caudal. Anal III 9-10; 
third spine longest, about 3 length of head ; middle soft rays produced, nearly as long 
as head. Caudal deeply emarginate, crescentic. Caudal peduncle 1} as long as deep.
