dorsal, its insertion being considerably nearer tip of snout in this 

 species, the interspaces between the dorsal spines being normally 

 greater; and by the marked differences in coloration. 



The Bureau of Fisheries steamer Albatross obtained examples of 

 this species from the following localities in the Philippine Archipelago: 

 Batan and Rapurapu Islands, Lagonoy Gulf, Luzon; Galvaney and 

 Alibijaban Islands, Ragay Gulf, Luzon; Port Dupon, Leyte; Murcie- 

 lagos Bay, Mindanao; and LTlugan Bay, near Rita Island, Palawan; 

 also from Soo Wan, Formosa; Si Amil Island, eastern Borneo; Binang 

 Unang Island, Gulf of Tomini, Celebes; and Gane Road, Gillolo 

 Island. 



Type.— Cat. No. 67354, U.S.N.M., 22.8 cm. in length, from Alibi- 

 jaban Island, Ragay Gulf, Luzon. 



HOLACANTHUS MULTIFASCIATUS, new species. 



Dorsal xiii,1 7; analni,16; scales 7 + 22 — 46. 



General form elliptical; head 3.25, upper profile steep, nearly 

 straight; body compressed, curvature of dorsal and ventral surfaces 

 similar, depth 1.55; caudal peduncle short and slender, depth 2.20; 

 eye 3.10, rather small; snout 2.75, short and blunt; mouth small, 

 terminal; maxillary short; nostrils of moderate size, the anterior 

 with a fold ending in a flap posteriorly, the posterior elliptical; inter- 

 orbital 3.50, flattened; preorbital armed with several strong, sharp 

 denticulations ; denticulations on vertical limb of preopercle well 

 developed; spine at angle strong, curved, longer than snout, two 

 weaker spines on horizontal limb; teeth fine, brush-like, trilobed, 

 lateral lobes small; rows of teeth distinct, with well-marked inter- 

 spaces; gill-membranes free from isthmus; peritoneum silvery-white. 



Scales regular in arrangement, those on middle of side slightly 

 larger than others; 30 transverse rows between opercle and end of 

 last vertebra; vertical fins and head finely scaled. Scales sub- 

 rhomboidal, strongly ctenoid; circuli fine, regular; basal radial folds 

 comparatively few, converging, and extending to nuclear region; 

 about 17 to 20 rod-like structures ending in a well-developed spine 

 extending from nuclear region to apical margin, characteristically 

 different from the sculpturing of the same region on the Chsetodon 

 scales. 



Dorsal spines slender, curved, fifth slightly longer than others, 1.46; 

 membranes of anterior spines deeply incised; soft dorsal higher than 

 spinous dorsal, evenly rounded; caudal short, margin rounded; anal 

 similar to soft dorsal; anal spines well developed; ventrals 2.65 in 

 length, first ray filamentous, its tip reaching base of second anal spine; 

 pectorals slightly longer than head. 



Color in alcohol: Dusky cream, crossed by ten seal-brown vertical 

 bands of about the same width as the interspaces; first band, the
