DISCUSSION OF SPECIES AND THEIR DISTRIUUTION. 347 



Gin rakers short, 8 below angle of first arcli, 4 of wliicli are rudimentary, the longest (2 

 millimeters) 5 in diameter of eye. (lu L. profiinilDrmn the gill-ralan-s are slenderer and 

 longer, though al)out equally numerous on the first arch.) 



Scales iu about 11 ro\ys from the origin of the dorsal to the median line of tlie body. 



Ventrals with length (13 millimeters) 3 in that of head. 



Dorsal origin far back, at a. distance from the snout (55 millinieters) 4a in total length; 

 at a distance from the eye er[ual to head's length. (In L. profniidornm this distancie is two- 

 thirds of the head's length and the first ray of the dorsal is nearly over the middle of tlie 

 extended pectoral; iu L. cerviiium, over its tip, or nearly so.) 



Anal origin witlt distance fi-om snout (84 millimeters) 3 in iotal lengtli. Length of pec- 

 toral (19 millimeters) 2 in head's length and 13 to 14 in tliat of body (10 in L. marmoratum, 

 11 in L. profiiiidiiruiii). 



Scales ornamented witli radiating striae, cover iiiu densely all ])arts of tlie lisli except 

 the snout and under surface of tlie head and the i'uin. Lateral line contiiuied almosf to the 

 end of the tail. 



Color brownish-yellow, with numerous subcii-c ular spots of white, with diameler half 

 that of eye along the upper half of the body. Vertical fins with narrow black margin. 



The type (Cat. :No. 28704, \J. S. N". M.) 2(i2 millimeters in lengtli, was taken by tlie 

 Fish ffawk from station 041, in 40^ 01' N. lat., Gl)o .^()' W. Ion., at a depth of 7(> fathoms. 

 A single specimen (Cat. No. 28;».jr), U. S. N". M.) was obtained by the same vessel from sta- 

 tion 1036, in 390 58' N. lat., 09'^ 30' W. Ion., at a depth of 94 fathoms. The A Uidlrosn also 

 secured examples (Cat. No. 3723G, U. S. N. M.) from station 2309, in 3.^-5 43' .30" N. lat., 7 I^.tj' 

 W. Ion., at a depth of r)6 fathoms; (Cat. Xo. 32053, IF. S. N. :\I.) from station 2001, in ;!7'^ 19' 

 45" N. lat., 740 20' 00" W. Ion., at a depth of 102 fathoins; and (Cat. No. 3723.-., IT. S. N. M.) 

 from station 2298, iu 35° 39' N. lat., 74° 52' W. Ion., at a depth of 80 fathoms.

The greatest height eijuals about a tenth of the extreme length, and is develoix'd at 

 the pectoral region; it thence almost uniforndy decreases to the end, and a,t the anus eipials 

 one-eleventh of the same; the thickness behind the pectoral fins equals sc^veii- tenths of the 

 height, and almost uniformly decreases to the end like the height. The anus is at the end 



of the first third of the length. 



The head forms rather less than a sixth of the length, aiul is tran.sversely convex ab()\e 

 and moderately inflated on the sides; the greatest width equals half its length. The eye is 

 rather longer than the snout, subcircular, and its diameter slightly exceeds two-sevenths 

 of the head's length; its pupil is small, the diameter equaling only a third of that of the 

 eye. The width of the interocular region rather exceeds two-ninths of the head's length. 

 The supramaxillary ends behind under the hinder margin of the pupil. 



The dorsal flu commt-nces nearly over the middle of the pectoral fin, and with the s(>c- 

 ond fifth of the length and is moderately high; the anal commences immediately behind the 

 anus, and is about as high as the dorsal; the caudal rays of the fin are the longest. Tlu^ 

 pectoral fin little exceeds half the head's length, and the longest branch of the \eiitial is 

 less than a third of the head's length, and three-fifths greater than the shorter. 



The color is a light rufous; the vertical fins inargined with black.
