OP FISHES FROM LAKE TANGANYIKA. 



Three specimens, dredged among shells in about 30 fathoms at Tembwi. 

 Nearly allied to L. hrevi 

 more numerous gill-rakers. 



Nearly allied to L. irevis. Differing in the truncate caudal and in the longer and 



41 . Lampkologcs brevis Blgr. 



This species was founded on a single specimen, 35 millim. long, obtained by Captain 

 Hecq at Albertville. The Cunnington collection contains two specimens, measuring 45 

 and 38 millim. respectively, from Rumonge, which agree very closely with the type, 

 but show variation in the fin-rays, viz.: — D. XVII-XVIII 7 ; A. VII-VIII 6. Depth 

 of body equal to length of head, 3 times in total length. 30 to 35 scales in a longitudinal 

 series ; scales on nape very small. Uniform brown above, whitish beneath ; fins brown, 

 without spots, dorsal tipped with black, ventrals black at the end ; opercular black 

 spot strongly marked. 



42. Lajiprologus cohpressiceps Blgr. 



A single young specimen from Niamkolo. 



The number of species of Lamprologus now known from Lake Tanganyika amounts 

 to 18, the principal characters of which are tabulated on p. 562. 



43. Telmatochromis temporalis Blgr. 



11 specimens from Kaboge, Mshale, Kituta, Mtondwe Bay, and Niamkolo Island. 

 Native names: Mbulila, Fisia (young), and Kamfoto (young). 



Dorsal XVIII-XX 7-10 ; Anal VI-VII 6-7 ; Sq. 40-47 ~ ; L. 1. 1 ~. 

 Dr. Cunnington describes the adult as olive, with dark patches in dorsal region and 

 irregular blotches on body and root of tail ; the temporal band orange; dorsal fin spotted 

 with yellow and white, and tipped with red ; caudal and anal spotted with yellow and 

 white. In the young the body may be crossed by dark bars ; the temporal band is 

 very distinct, and the bar at the base of the pectoral fin is edged with whitish behind. 



44. Paratilapia frontosa, sp. n. (Plate XXXVII. fig. 1.) 



Depth of body twice and ^ in total length, length of head nearly 3 times. Forehead 

 gibbose l , the head at the interorbital region as deep as the body ; snout twice and ^ 

 as long as the eye, the diameter of which is contained 5^ times in length of head and 

 nearly twice in interorbital region ; maxillary not extending to below anterior border 

 of eye ; 3 series of teeth in each jaw, outer large ; 5 series of scales on the cheek ; 

 large scales on the operculum. Gill-rakers rather long, 13 on lower part of anterior 

 arch. Dorsal XIX 8 ; spines increasing in length to the last, which measures a little 



1 Probably in adult males only.
