clu corps sont un peu simieuses a leur bord posterieur, et quelques-unes echancrees au 

 milieu. Les epines de I'anale sont tres faibles. Ce poisson est d'un gris blanc ; la 

 caudale est noiratre, avec le milieu jaune; I'anale est semblable, mais le jaune est 

 moins eclatant ; la dorsale est grise, variee de jaune, et les pointes sont rougeatres. Les 

 ventrales, les pectorales et le ventre sont d'un blanc jaunatre. Les dents fines, sur 

 plusieurs rangees tres irregulieres ; beaucoup d'entre elles sont terminees par deux 

 ou trois tubercules, Dorsale, 16/11. — Anale, o/lO. — Caudale, 16. — Pectorales, 15. — 

 Ventrales, 1/5." 



C. sparmanni of Castlenau belongs probably to the same species, as far as can be 

 guessed from the following definition : — 



"Longueur, Om. 19 ; corps haut et assez court; pectorales un peu prolongees a leur 

 partie anterieure, et atteignant presque la base de la dorsale ; dents assez fortes, 

 avancees, serrees, longues et terminees par deux tubercules ou pointes mousses, dont 

 I'une est un peu plus longue que I'autre ; epines de I'anale faibles ; corps d'un vert 

 obscur ; caudale ayant sa premiere moitie d'un rouge fonce et I'autre d'un blanc 

 verdatre ; I'anale, les pectorales rougeatres ; la dorsale d'un gris noir ; ventrales d'un 

 blanc sale. Dorsale, 16/12. — Caudale, 16. — Anale, 3/10. — Ventrales, 1/5. — Pec- 

 torales, 14." 



Mr. Woosnam's specimens, nine in number, are here described. 



Depth of body 2 to 2-|- times in total length, length of head 3 to of times. Head If 

 to twice as long as broad ; snout rounded, with straight or convex upper profile, as 

 broad as or a little broader than long, as long as or shorter than postociilar part of head ; 

 eye 4 to 5^ times in length of head, |- interorbital width, equal to or a little less than 

 prseorbital depth ; mouth moderate, f to | width of head ; maxillary extending to 

 between nostril and eye ; teeth very small, in 5 or 6 series, 70 to 110 in outer series of 

 upper jaw ; 2 or 3 series of scales on the cheek, the width of the scaly part not greater 

 than diameter of eye. Gill-rakers moderately long, 20 to 25 on lower part of anterior 

 arch. Dorsal XV-XVII 12-13; spines increasing in length to the last, which 

 measures f to a little over ^ length of head ; longest soft ray f to f length of head.

3- 18-23 



than long. Scales finely granulate, not denticulated, 31—33 i?^; lat. 1. jgrjg. 



Mr. Woosnam has made two coloured sketches of the fish obtained by him (native 

 name : Nchanu). The first fish is dark brown, the scales edged with bluish white ; 

 lower half of head and pectoral region bluish white, the former with large black spots 

 and a dark blue opercular spot ; dorsal and anal brown, with large round white spots 

 the former edged with red, the latter with purple ; caudal purplish red, spotted with
