114 A Collection of Fishes from Samoa. 



Anarchias allardicei (Jordan and Seale). 

 Head 6.87; depth at vent about 15.25; head width 3.16 in its length; head depth 2.87 ; 

 snout 5.75; eye about 9; mouth 3.12; interorbital 5.75. 



Body moderately short, well compressed, rather deep, with convexly flattened sides 

 and taU tapering rather abruptly behind. Combined head and trunk 1.2 in rest of 

 body. 



Head moderate, compressed, depth slender and pharynx not swollen, about even 

 in width, convex above and below. Muzzle rather obtuse, upper profile slightly con- 

 cave over eye. Snout obtuse, convex at tip and on dorsal surface, length three-fourths 

 its width. Eye rounded, about median in depth over mouth, little backward in gape 

 length, without eyelids. Mouth rather small, horizontal, completely closes. Lips 

 rather tough, fleshy, entire along edges. Teeth conic, entire, subequal, strong. 

 Upper teeth with one series small, mostly uniform and erect all around outer edge of 

 jaw and inner series of enlarged, depressible, wide-set sharp-pointed teeth on both sides. 

 Lower jaw with similar dentition. Front of vomer with two large fangs and row of 

 few small teeth down its shaft behind. No tongue. Upper jaw tip slightly protrudes, 

 and mandible with strong rami. Anterior nostril short, fleshy tube about as long as 

 pupil, near snout tip. Posterior nostril simple pore over eye center within interorbital 

 space, which is convex. Occipital region not especially swollen, convex. 



Gill-opening close to ventral profile, as simple pore, size of posterior nostril. 

 Pharynx smooth. 



Skin smooth, tough, 5 pores along each side of upper hp, first in front of anterior 

 nostril, second close behind base of anterior nostril, third nearer eye than second, 

 fourth below front pupil edge, and fifth close behind eye. Pair of pores above, close 

 to and within front internasal space, second pair midway on snout above, third pair 

 adjoin hind nostrils over eyes. Lower edge of mandible with 5 pores each side^ grad- 

 ually more distant from one another backward. No lateral fine. 



Dorsal begins as very slight ridge over gill-opening; extends back also as very 

 slight fold to caudal, where it is a little broader. Caudal rounded, about as long as eye. 

 Anal developed only as low fold on under surface of tail about last two-elevenths of its 

 length, continuous also with caudal. 



Color in alcohol uniform dusky brown above. Under surface of head, belly, and 

 end of tail tinted brownish; hind edge of latter whitish. Iris pale slaty. 



One example, 116 mm. long, from Pago Pago. 



Varies from the original account in the presence of two large anterior vomerine 

 teeth, and no smaller posterior vomerine teeth are mentioned by its describers. The 

 figure of A. allardicei shows the dorsal origin beginning apparently nearer the mouth 

 corner than the gill-opening, while in our example it begins over the gill-opening. 

 A . allardicei has been united^ with A.knighti Jordan and Seale, but its mottled coloration 

 and more elevated dorsal doubtless renders it distinct. 



HEMIRAMPHIDiE. 



Hyporhamphus pacificus (Steindachner). 



Head from upper jaw tip 4.6; depth 9.33; D. iii, 14; A. iii, 16; P. i, 10; V. i, 5; 

 scales 66 in lateral series from shoulder to caudal base and 6 more on latter; about 7 

 scales above lateral line to dorsal origin; 2 scales above anal origin to lateral fine; 

 snout about 2.66 in head without beak; eye 3.33; maxillary 4.5; interorbital 4.33; 

 pectoral 2.25; first branched dorsal ray 2.87; first branched anal ray 3.5; least depth 

 of caudal peduncle 5.25; lower caudal lobe 1.25; ventral 3.2. 



Body elongate, rather robust, slightly compressed, though sides are convex and 

 not flattened, deepest medially. Caudal peduncle compressed, least depth half its 

 length.
