LONNBERG, FISHES. 



trr has a greater number of anal rays (23) and of scales in the lateral line (40) and its 

 height is only contained :>' :i times in the total length. P. leopoldianus BOULENGER 

 from the same locality as P. modesiiis has a greater number of anal rays (22 23), a 

 smaller number of scales in the lateral line (30 31), its body has a different shape, be- 

 ing expanded at the base of the anal fin. The remaining four species have a greater 

 depth of body and at the same time fewer scales, except P. hilgendorfi, from Lake Leo- 

 pold, which has about the same number of scales but a longer anal fin with 23 26 rays. 

 The six species of /Y/<r.sv.v known up to 1899 are reviewed by BOULENGER in 

 Annales du Musee du Congo, zool. T. I Fasc. 4. A seventh species P. grandis from 

 Southern Cameroon is described by the same author in The Annals and Magazine of 

 Nat. Hist. (7) Vol. 12 1903.

 1 specimen from a small tributary to the river Sanya, Kilimandjaro low lands 

 ' , 1906. -- 1 specimen from the river Sanya, Kibonoto 28 /2 1906. 



This species also is described from the Kenya district from the head- waters 

 of Nyiro River at an altitude of 7,000 feet. (Proc. Zool. Soc. 1905 Vol. 1, p. 62.) A 

 synopsis of the other 6 african species of this genus has been communicated by BOU- 

 LENGER in Proc. Zool. Soc. 1903 II p. 331. 



This genus is not recorded by PFEFFER in Die Thierwelt Ost-Afrikas . 



inacro]ristis merneiisis n. subsp.? 



9 specimens from the river Ngare na nyuki, coming from the Meru mountain, 

 -" 10 1905. D. Ill, 7, S. Ill, 5, L. lat. 3638. 



Depth of body 3 2 /3 to about 4 times; length of head about 4 times in total length 

 without caudal. Snout and diameter of eye subequal about 3 3 /4 to 4 times in head; 

 interorbital width 2 1 /s times in head. Anterior barbel about as long as Va diameter 

 of eye, posterior about equal to diameter of eye. Last simple ray of dorsal not quite 

 as long as head, rather strongly serrated behind along its outer two thirds. Ventrals 

 situated in advance of dorsal. Depth of caudal peduncle about 4 /i of its length. 7 sca- 

 les between lateral line and origin of dorsal, 3 between lateral line and ventrals. Silvery 

 with a dark band along the side above the lateral line, a black spot at the base of the 

 caudal, lateral line blackish. Largest specimen 75 mm. 



This fish is no doubt very closely allied to Barhn* tuacropristis BOULENGER from 

 Lake Victoria and perhaps only a local variety of the same. The latter species has the 

 last simple ray very strong, bony, strongly serrated behind, nearly as, long as or a little 

 longer than head, and no markings. The differences may perhaps be due to different 

 age as BOULENGER'S specimens were a little larger, (128 mm.), or the specimens from 

 the small waters of the Meru may always remain in a juvenile stage compared with those 

 of the great lake.
