ring below the centre of the eye is one-thii-d of the greatest, breadth 

 of the praeorbital. The soft dorsal fin is produced into a point, the 

 fom-th and fifth rays being the longest; caudal fin forked. 13ody 

 v/ith five blackish cross-bands, which are not broader than the inter- 

 spaces between them : the first from before the origin of the spinous 

 dorsal to the base of the pectoral fin ; the second from the fourth, 

 fifth and sixth dorsal spines towards the middle of the ventral fin ; 

 the third from the tenth, eleventh and twelfth dorsal spines towards 

 the anal spines ; the fourth from the middle of the soft dorsal to the 

 middle of the anal ; the fifth across the middle of the free portion 

 of the tail. 



From the Red Sea through all the Indian Seas to Polynesia.

Whilst I cannot hesitate to consider G. rahti and G. ccelestinus as 

 individual varieties of one and the same species, G. waigiensis may 

 be really different, and distinguished by a more elevated body, the 

 depth of which is three-fifths of the total length (the caudal fin not 

 included) ; it has been described by Quoy & Gaim. Voy. Uran. Zool. 

 p. 391, and by Cuv. <fe Val. v. p. 457. The following specimens in 

 the British Museum Collection appear to belong to this species or 

 variety : — 



a. Half-grown. Sandwich Islands. From the Berlin Museum. 

 h. Half-grown : stuffed. 



* It is very probable that this is the specimen mentioned by Sir J. Richardson 

 as Glj/phhodon fjjrwhitti {I. c.) ; its teeth are in a singje series as in the other 

 Glyphidodonts ; and we suppose that Sir J. Bichardson considered the broad- 

 toothed Cliincse .species (G. scpfcmfascinfus) as G. coefcsfinus, which, in fact, has 

 the teelh as narrow and slender as in G. .faj^afi/is.
