ridge of abdomeu, its base rather long. Dorsal flu beginning above eye; caudal double 

 truncate; anal without si)inc. Scales thin, deciduous, ctenoid on left side, cycloid on blind 

 side. Lateral line simple, nearly straight. Si/,(^ small, (ienus aijparently allied to Vitha- 

 richthys, althougii the mouth is very sniidl. {■lonhtn :ind Gilhcrt.) 



ETROPUS KIMOSUS, (iooi.i; :iiiil Hkan. ( Kigurt'H 3I)0, 361). 



Etropua rimosus, Goode .uiil Hkan, Proc. U. S. Nat. Miis., viii, 1885, 593. 



Body pear-shaped, its height (.51 millimeters) slightly exce(Mling h;ilf its length. 



Scales large, strongly pectinated on both sides, about 41 in tlu', longitudinal series, 12 

 above and 14 below the lateral line. Lateral line equally developed on both sides, very 

 slightly curved above the pectoral. Head entirely covered with scales. Numerous small 

 supernumerary scales between the normal scales covering their surface. 



Length of head (21 millimeters) slightly less than one-fourth of tlie total length. 

 Snout very short, its length (3 millimeters) S times in that of head. Mouth very snuill, its 

 cleft less than diameter of orbit, its angle reaching about to verti(;al through anterior mar- 

 gin of lower eye. 



The length of this maxilla (5 millimeters) somewhat less tlian one fourth that of head. 

 Length of numdible considerably more than one-third of the same length. 



Teeth well developed on blind side in botli Jaws, also on the colored side of lower Jaw 

 in front. 



Eyes moderate (7 millimeters), their diameter contained nearly 3^ times in length of 

 head, placed in the same vertical, the upper eye close to the dorsal profile, and separated 

 from its mate by a space less than one-third of its own diameter. Interorbital ridge low. 



Nostrils in line with the interorbital ridge, each in a short tube, the posterior being the 

 larger. The anterior lutstril is ecjuidistant from the tip of the snout and the lower oi-bit. 

 Dorsal flu commencing at a point upon tlie blind side of the snout in the vertical through 

 the anterior margin of the eye, containing 77-78 rays, the longest somewhat behind the 

 middle of the fin, its length alxjut 7 times in. total length. 



Anal tin comnieucing under the base of the pectoral, composed of (il rays, the longest 

 post-medial as long as the longest in the dorsal. Anal papilla prominent. 



Caudal fin rounded, the middle rays about as long as the head. 



Pectorals normally jilaced, that upon the colored side longest, equal in length to that 

 of the head without the snout. 



Venti-al of eyed side on ridge of abdomen, its base rather long but not reaching anal 

 origin; that of blind side farther forward, its length equal to that of its mate, and i\ little 

 more tliau one-tenth of the total. Vent at the anal origin slightly lateral. 



Color, gray, hoary above, with a few irregularly placed indistinct brownish blotches, 

 none of which are larger than the eye. White below. 



Eadial formula: D. 77-78; A. 01; V.d; P. I»-ll; C. 17; scales, 41. 



The type is Cat. No. 37332, 100 millimeters long; it is from station 2408, Albatross, N. 

 lat. 280 28', W. lou. 84° 25', depth 21 fathoms. 



CYCLOPSETTA, Gill. 



Cyclopsetta, Gill, Proc. II. S. Nat. Miis., 1888, 601. 



Psettines with the body oblong rhombo-ovate, covered with regularly imbricated mod- 

 erate cycloid scales; lateral line nearly rectilinear on both sides; snoutconvex; mouth very 

 large; Jaws .squarely truncated behind; teeth nniserial, those of upper jiiws moderate, of 

 h)wer jaw enlarged and largest at sides; dorsal and anal almost symmetrical, dorsal com- 

 mencing in front of eye on snout, scarcely deflected on blind side; caudal slightly ])ediin 

 culate and convex; pectorals subequal and with a subtruncate free margin; ventnils nearly 

 equal, the left on the preanal ridge, the riglit lateral, both with the inner rays connected by 

 membiane to the body; interl)ranchiid meniluaiie imperforate; gill rakers tubercular and 

 surmounted by blunt denticles.
