560 ME. G. A. BOULEN&ER Oi\ A COLLECTION 



Allied to L. lemairii and L. hecqui. Distinguished from the former by the longer 

 gill-rakers, the broader interorbital space, fewer scales in a vertical series, and more 

 numerous soft rays in the anal fin ; from the latter by larger scales and 8 anal spines 

 instead of 6 or 7. 



39. Lamprologus reticulatus, sp. n. (Plate XXXV. fig. 4.) 



Depth of body 4 times in total length, length of head 3^ times. Snout pointed, as 

 long as the eye, the diameter of which is contained 3^ times in length of head and 

 equals interorbital width ; maxillary extending to below anterior fourth of eye ; canines 

 very small, followed by a narrow band of minute, villiform teeth ; a few scales on the 

 cheek; operculum with large scales. Gill-rakers short, ]4 on lower part of anterior 

 arch. Dorsal XIX 10, spines increasing in length to the last, which measures ^ length 

 of head ; longest soft dorsal ray but slightly longer than longest spine. Anai VIII 8, 

 last spine as long as last dorsal spine. Pectoral rounded, f length of head. Ventral 

 extending to origin of anal. Caudal truncate, slightly emarginate. Caudal peduncle 

 once and ^ as long as deep. Scales 39 ^ ; lateral lines =^. Brown, the scales edged 

 with darker, forming a reticulate pattern ; dorsal and anal fins dark brown, with oblique 

 rows of round whitish spots; caudal fin brown, with numerous, rather indistinct light 

 spots at the base, and an oblique whitish streak in the upper corner. 



Total length 62 millim. 



A single specimen from Vua. Native name : Zagezi, like L. callipterws. 



Distinguished from L. callipterus, the young of ^'\'hich it resembles in coloration, by 

 the truncate caudal fin and the smaller teeth. 



40. Lamprologus calliueus, sp. n. (Plate XXXV. fig. 5.) 



Depth of body 2f to 3 times in total length, length of head 3 times. Snout obtuse, 

 a little shorter than the diameter of the eye, which is \ length of the head and a little 

 greater than interorbital width ; maxillary extending to below anterior fourth of eye ; 

 outer canines strong, curved ; a narrow band of minute, villiform teeth ; cheek naked ; 

 operculum scaly. Gill-rakers long and slender, 14 to 16 on lower part of anterior 

 arch. Dorsal XVII-XVIII 7 ; spines subequal from the eighth or ninth, measuring 

 about -g- length of head ; soft rays a little longer. Anal VIII 6-8, last spine nearly as 

 long as longest dorsal spines. Pectoral rounded, f length of head. Ventral extending 

 beyond origin of anal. Caudal truncate. Caudal peduncle a little deeper than long. 

 Scales 35-36 ~^; lateral lines ^j^. Yellow, brownish on the back, with rather 

 indistinct darker bars across the back and across the caudal fin; a sharply defined 

 hlack opercular spot, edged with silvery in front. 



Total length 50 millim.
