(Plates XXVII to XXX.) 



The four species here described and figured have hitherto been only very 

 bi-iefly characterised, and their recognition has been a matter of soine little 

 difficulty. Pomacriifnis apicalis, De Vis, and Cantherincs bruiinfiis. Castelnan, 

 have not been recognised since they were originally described over thirty year.s 

 ago. 



Family POMACE^TRID^E. 



Genus POMACENTRUS, Laeepede. 



POMACEiVTRUS APICALIS, de Vis. 



(Plate XXVII.) 



i'omaccntrus apicalis, De Vis, Proc. Linn. Soe. N. S. Wales, ix, 1S85, p. 874. 



D. xiii/16; A. ii/13; P. 20; V. i/5 ; C. 15; L. lat. 20; 27 rows of scales 

 between the operculum and the hypural joint ; L. tr. 34/11. Depth before the 

 ventrals 2 into the length of the hypural .ioint; head 3-3 in the same. Eye 

 slightly narrower than the interorbital width, as long as the snout, and 3-5 in the 

 head. 



Body short and deep. Head slightly longer than deep. Snout obtusely 

 pointed, the maxilla reaching .slightly beyond the anterior margin of the eye. 

 Suborbital strongly denticulate on its postero-inferior margin. Preopereulum 

 denticulate on its hinder limb, the angle rounded. Operculum with a small 

 flat si)ine. Head, body, and vertical fins closely covered with scales, the edges 

 of which are minutely ciliated ; they extend forward to between the nostrils and 

 cover the greater part of the suborbital bone, leaving only the end of the snout 

 naked. Nostril a little nearer the eye than the end of the snout. Dorsal 

 originating above the end of the operculum ; the spines increase gradually in 

 length backwards, and there is no indentation between the spinous and soft 

 dorsals; the soft dorsal angular, its median rays longest. Second anal spine as 

 long as the distance between the preopereulum and the snout, and longer than 

 the dorsal spines ; soft portion of fin rounded. Caudal bifurcate, the upper lobe 

 longer than the lower. First ventral ray filamentous, reaching the second anal 

 spine.
