allied fish (the angler), which is supplied with a far less complicated attach- 
ment, have been closely studied and proved it to be ** a fish which angles for 
fish,” with a natural rod, line, and bait, and with certainly as deadly a 
“creel” as any human disciple of Isaac Walton might have to which to 
relegate its captives. 
I take this opportunity, too, of acknowledging with thanks the kindness 
of Mr. Appel, V.S., of this town, to whom this last fish was sent by its 
collector, and who has kindly allowed me to figure and describe it.

D. 1-7; P. 7; V. 6, single; A. 7; C. 24. 
The height of the body equals length, and is less than the distance 
between gill-covers and root of caudal; the length of head is contained 
three times in distance from end of chin to root of caudal ; tail very slender ; 
abrupt termination of body midway between tip of snout and end of caudal 
fin (expanded); osseous dorsal plate with one double and four (last very 
minute) spinous processes imbedded in its substance ; pectoral fin barely 
reaches to ventral; orbit of eye oblong, pupil on summit; eyes approach 
very close together on top of head; posterior margin of preoperculum 
almost borders hind part of orbit, descends in straight line and terminates 
in a double spine, the superior curving upwards, inferior continuing in 
direction followed by margin; prominent spine at posterior corner of 
mandibles ; spine on chin, pointing directly forwards ; spine over temporals; 
spine on throat, before commencement of serrature ; serrature terminates 
in double pubic spine, the inferior portion of which is curved and barbed, 
presenting a very formidable armature though on so small a scale; no 
appearance of adipose fin; commencement of soft dorsal fin midway 
between snout and end of tail ; pectoral and caudal fins well developed ; one 
ventral fin only, placed in median line of body above pubic spine; four 
luminous spots on lower side of tail before commencement of caudal fin ; 
six over and partly behind anal fin, and three immediately in front of same, 
all surrounded with black skin; long luminous streak on lower abrupt 
termination of body above pubic spine; along lower sides of body a superior 
row of spots, ten in number, to base of pectoral fin, and an inferior series, 
thirteen in number, terminating in vertical with posterior limb of preoper- 
culum, each spot in the above two rows being in intervals between ribs, which 
are very prominent, giving a striate appearance to body ; under margin of gill- 
covers, and on throat before pectorals, a series of four spots ; single series 
of recurved conical teeth, minute at angles of gape on upper jaw, large 
towards centre of upper and lower jaws; tongue thick and fleshy ; sides of
