CICHLID FISHES OF LAKE NYASSA. 701 



last spine f to ^ length of head. Anal III 8-9 ; third spine ^ 

 to |- head. Pectoral as long as head, extending nearly to middle 

 of anal. Caudal emarginate. Caudal peduncle If to 1§ as long 

 as deep. Silvery ; a blackish spot on operculum ; two large 

 blackish spots on upper lateral line, expanding upwards towards 

 spinous and soft dorsal ; a blackish spot at base of caudal. 

 Dorsal and caudal with series of orange spots ; males with a 

 pale edge to dorsal and lower fins dusk}^, the anal with ocelli. 

 Five specimens, 130 to 180 mm. in total length (Wood).

Parafilapia intermedia (part.) Bouleng. Cat. Afi-. Fish. iii. 

 p. 363. 



Depth of body 2| in length, length of head 3. Snout with 

 straight profile, shorter than postorbital part of head. Diameter 

 of orbit nearly equal to depth of prteorbital, which is 4^ in 

 length of head. Jaws equal anteriorly or lower perhaps slightly 

 projecting ; lower jaw ^ length of head ; prtemaxillary pedicels 

 not reaching orbits ; maxillary not extending to below eye ; 

 teeth small, conical, in 2 or 3 sexies, about 70 in outer series of 

 upper jaw. 4 series of scales on cheek. 34 scales in a longi- 

 tudinal series, 5 from origin of dorsal to lateral line. Dorsal 

 XVI 11 ; spines strongly increasing to last, which is nearly g 

 length of head. Anal III 9 ; last spine i head. Pectoral as 

 long as head, reaching anal. Caudal rather deeply emarginate. 

 Caudal peduncle a little longer than deep. Silvery ; traces of 

 two dark spots on upper lateral line ; dorsal with series of spots 

 and a pale edge ; anal with several spots. 



The type, a skin, 185 mm. long. 



Boulenger's figure (Cat. Afr. Fish. iii. fig. 247) represents the 

 body and fins correctly, but the head is inaccurate, the praeorbital 

 being too narrow ; also the four black spots depicted are taken 

 from a specimen of II. qiLadrimaculatus. 



H. intermedius is Avell distinguished from H. quadrimactdatus 

 by the deeper prteorbital, deeper cheek with 4 series of scales, 

 shorter prsemaxillary pedicels, the number of dorsal spines (16 

 instead of 17 or 18), and the form of the spinous dorsal fin. It 

 shows much closer agreement with H. placodon, but has the 

 teeth in fewer series, smaller, and conical instead of cuspidate ; 

 also the lower jaw is notably longer. 



22. Haplochromis modestus Giinth., 1893. 



Paratilajna modesta (part.) Bouleng. Cat. Afr. Fish. iii. p. 326, 

 fig. 219. 



Depth of body 3 in length, length of head 2-?. Snout with 

 straight profile, as long as postorbital part of head. Diameter 

 of eye 4^ in length of head, a little greater than prseorbitnl 

 depth, equal to depth of cheek; interorbital width 5 in length
