 L'S; to upper axil of pectoral 14; distance from lip of snout to upper axil of pectoral exceeding the dis-

Head slender, flattened above, its upi)er profile evenly curved, nuchal region not gibbous; snout 

 ending in a fleshy tip extending well beyond front of vomer and slightly beyond mandibidar tip; front 

 of vomer about opposite anterior nostril; posterior nostril a round pore with margins very slightly 

 raised; anterior nostril a short tube directed forward; distance from posterior nostril to eye equaling 

 one-third the interval between nostrils; mandibular teetli minute posteriorly, in a narrow band which 

 nan-ows anteriorly to a single series of slightly enlarged teetli; maxillary teeth similar, in a wider

somewhat larger than the other.<; a prominent ellii)tical patch of teeth on head of vomer, those on 

 median line a little laiger than any other teeth in mouth; a single series of small conical teeth along 

 shaft of vomer. 



Scales narrowly elliptical, arranged in groups with tlieir axes at right angles to each other, ab.sent 

 on (ins, snout, and under side of head; lateral line ]ironiinent, ojiening by small pores arranged jirinci- 

 pally along its lower margin, each pore with rai.sed margins; lateral line nearer the dorsal than the 

 ventral outline, until it appn.iaches within less than a head's length of the tip of tail. 



Color, warm brown, darker on fins and under side of head; fins all distinctly white-marginecl; 

 buccal and gill-cavities, and body cavity lined witli blackish membrane. 



In the 2 smallest specimens, 19 and 3») cm. long, the body and flns are much lighter in color, the 

 lins almost perfectly translucent in the .smallest. In both, the caudal and the posterior jiart of ilor,'<al 

 and anal are jet-blaclv, without white edging. The origin of the dorsal varies somewhat in position, 

 but is a little in advance of the anal in only one specimen. 



Most nearly related to .S'. ]>iniiiilii.s ((ironow) and .S. iiffiniK Giinther, <liffering in the much shorter 

 trunk, and in the white margins of the lins. Kxamjiles were taken at the following stations: Xos.
