A Collection of Fishes from Samoa. 115 



Head compressed, flattened sides approximated below where width is half that of 

 cranium, well attenuated forward. Snout long, depressed, width 1.75 in its length. 

 Eye elongately ellipsoid, close to upper profile, slightly advanced in head (without 

 beak). Free portion of upper jaw nearly an equilateral triangle as seen from above, 

 its length 2.4 in snout. Maxillary 1.5 to eye, broadly vertical, width equals pupil. 

 Lower jaw long, slender, so rest of head from upper jaw tip only 0.75 of remainder of 

 beak. Teeth fine, simple, in narrow bands in jaws. Upper buccal fold narrow, lower 

 broader. Tongue elongate, depressed, smooth, free. Nostrils rather large, together, 

 their depression as long as pupil along upper snout edge close before eye. Interorbital 

 depressed to very slightly concave. Opercle broad, smooth, width 1.25 eye diameters. 

 Preorbital slightly less than eye. 



Gill-opening forward to front eye edge. Rakers 10+23, lanceolate, 1.5 in gill- 

 filaments and latter 1.75 in eye. Isthmus narrowed, trenchant frenum in front. 



Scales deciduous, all well imbricated and above computations, largely according 

 to pockets. Dorsal and anal mostly covered with small scales, at least basally, also 

 caudal base. Scales with basal circuli 19. Lateral Une complete, apparently low 

 along side, touches at ventral origin, tubes simple and each well exposed. 



Dorsal origin well posterior, much nearer caudal base than ventral origin or little 

 behind last third in space between caudal base and pectoral origin, anterior rays longest, 

 though their tips extend only to middle of fin when depressed, and entire depressed 

 fin three-fourths to caudal base. Anal inserted opposite dorsal, similar. Caudal 

 well forked, lower lobe much longer than upper (damaged). Pectoral base high, fin 

 4 to ventral origin, latter midway between pectoral origin and caudal base, fin short or 

 but 2.25 to anal. Vent close before anal. 



Color in alcohol brownish on back, paler on under side, apparently whitish in life. 

 Down middle of back well-marked dusky line with narrow one each side and parallel, 

 also scale edges same tint. From shoulder, narrow silvery-white band to caudal base, 

 widest below dorsal, where about two-thirds vertical eye diameter, and its upper border 

 tinted slaty narrowly or with deeper line. Fins all pale brownish, vertical ones and 

 pectoral above tinted little with grayish. Iris silvery white, also side of head. Inside 

 gill-opening marked with dusky dots. 



One 205 mm. long, from Pago Pago. Agreement was found with Hawaiian examples, 

 which have rakers 9-f 22. 



Hyporharnphus samoensis Steindachner,* as suggested by Giinther, is probably the 

 same. This species is doubtless identical with HemiramphuH dassumieri Valenciennes. 



MUGILIDiE. 



Neomyxus chaptali (Eydoux and Souleyet). 



Head 3.4; depth 3.4 to 3.5; D. IV-I, 9; A. Ill, 9; scales 37 to 39 in median lateral 

 row to caudal base and 5 more on latter; 12 or 13 scales transversely between dorsal 

 and anal origins; about 21 or 22 predorsal scales; snout 3.5 in head; eye 3.25 to 3.33 

 in head; mouth width 2.87; interorbital 2 to 2.4. 



Body compressed. Head broad above, constricted below, upper profile nearly 

 straight. Snout broadly obtuse as seen dorsally, length two-fifths its width. Eye large, 

 posterior edge midway in length of head, rim free. Premaxillaries concealed. Upper 

 front lip thick, width slightly over half of eye. Edges of lips with single row of rather 

 large fleshy papillae. Mandible included in upper jaw. Nostrils small, close, near 

 upper edge of snout. Interorbital broadly convex, with shght depression in front. 

 Rakers 22+36, slender, lanceolate, little less than filaments, the latter 1.66 in eye. 

 Scales large, firm, in even longitudinal rows; basal radiating strise 4 to 6, with 3 to 5 

 incomplete accessory ones; circuli rather coarse. Dorsal, anal, and caudal largely
