OF FISHES FROM LAKE TANGANYIKA. 555 



Seekanidj;. 



27. Lates microlepis Blgr. (Plate XXXV. fig. 2.) 



Several specimens, measuring from 60 to 410 millim., from Niamkolo and Kituta. 

 Native name : Pamba or Sangala. 



Dr. Cunnington has taken a photograph of a specimen measuring 1*34 in. 



28. Lates axgustifroxs, sp. n. (Plate XXXV. fig. 1.) 



Depth of body 3^ times in total length, length of head 3 times. Upper profile 

 of head nearly straight ; diameter of eye 4^ times in length of head, once and -§- in 

 length of snout ; interorbital space narrow, only | diameter of eye ; lower jaw 

 projecting ; maxillary extending to below centre of eye, the width of its distal 

 extremity J diameter of eye ; pra> and suborbitals finely serrated ; cheeks, opercles, 

 and occiput covered with small scales ; praeopercular border forming nearly a right 

 angle, finely toothed on its vertical limb, with three widely separated spines on its 

 lower limb, and with a very strong spine at the angle ; two strong opercular spines. 

 4 or 5 strong spines on the clavicle. 14 gill-rakers on lower part of anterior arch. 

 Dorsal VII, I 12 ; third spine very strong, longest, about ^ length of head ; longest 

 soft rays -^ length of head. Anal III 8 ; spines short, second and third equal. 

 Pectoral not quite ^ length of head. Caudal rounded. Caudal peduncle once 

 and |- as long as deep. Scales 125 n§. Dr. Cunnington describes the coloration 



as of a yellowish tinge all over, darkish grey above, shading to almost white below ; 

 middle region of body faintly mottled with darker grey ; ventral fius yellowish. 



Total length 265 millim. 



A single specimen from Niamkolo. Native name: Pamba ekundu (Red Pamba). 



This species, although very closely related to the preceding, is easily distinguished 

 from it by its much narrower interorbital region 1 and by the rounded caudal. 

 According to Dr. Cunnington, the natives regard this fish as distinct in kind from 

 L. microlepis, and they say it does not grow so large, the specimen here described 

 being regarded by them as of the full size.

29. Lamprologus breviaxalis, sp. n. (Plate XXXVI. fig. 1.) 



Depth of body 3|- times in total length, length of head 3 times. Snout pointed, a 

 little longer than the eye, the diameter of which is contained o\ times in length of 

 head and equals interorbital width ; maxillary extending to below anterior border 



1 In the young L. microlepis the interorbital width equals at least -?- the diameter of the eye, and it equals 

 | in a specimen nearly equal in size to tho type of L. angustifrom (total length 245 millim.). An uppor view 

 of the head of this specimen is given on PI. XXXV. tig. 2, for comparison. In a specimen 450 millim. long 

 the interorbital width equals once and i the diameter of the eye.
