 Plateasa qiKidiociilaris, (iiLi,, Cat. fish. K. Coast N. A., 1861,51. 



Body much compressed, elongate, its greatest height less than two-fifths of its length. 

 Head rather short, its length one fourth that of body. Eyes separated by a prominent, 

 narrow, sharp ridge, the diameter of the orbit nearly one-fourth of the length of the head. 

 Upper jaw with very numerous, small, close set teeth laterally, and 4 or 5 canines in front; 

 the lateral teeth abruptly smaller tha;i the anteiior; lower jaw with 7 to 10 teeth on either 

 side. Maxillary narrow, reaching past vertical from middle of pupil, its length two and 

 one-fourth times in that of head. Scales weakly ctenoid or cycloid, over 90 in lateral line. 

 Gill rakers thick and rather long, about 8 below angle. Dorsal low, beginning over front 

 of eye, some of the anterior rays exserted, the longest rays behind middle of fin, their 

 length not quite half that of head. No anal spine. 



Eadial fornnda: D. 72-80; A. .59-76. 



Color, brownish gray, mottled; 4 large black ocelliP-, each surrounded by a lighter mar- 

 gin; 2 behind middle of body, 1 below dorsal, and 1 above anal; 2 smaller spots near hist 

 rays of dorsal and anal. 



This is a well marked species, known for many years as an inhabitant of moderate 

 depths along the coast from Florida north to JNIassachusetts. The northern limit of its range 

 is marked by the capture of a single small individual in 1877, off the mouth of Salem Harbor. 



It is not properly a deep sea species, but is included in the list on account of its occiir 

 sional capture at the hundred fathom line. 



The Fish Hawk obtained a single individual (Cat. No. 26078, U. S. N. M.) from station 

 873, in 40° 02' N. hit., 70° 57' W. loi:., at a depth of 100 fathoms; and the Alhotross took it 

 from station 2307, in 35° 42' N. lat., 74° 54' 30" W. Ion., at a depth of 43 fathomsj from 

 station 2313, in 32° 53' N. lat., 77° 53' W. Ion., at a depth of 99 fathoms; from station 2421, 

 in 370 07' N. Lit., 74° 34' 30" W. Ion., at a. depth of 04 fathoms; Cat. No. 2S8G1, U. S. N. M., 

 from Buzzards Bay; aud 11 single specimen fiom station 2297, in 35° 58' N. lat., 74° 53' W. 

 Ion., at a depth of 49 fathoms. 



Giinther enumerates other species of raraJichthyn from deep waters, namely, Para- 

 lichthys Ilectorin, (Giinther,) from 150 fathoms, off New Zealand; P. bijops, (Uector,) off 

 Cape Farewell, 400 fathoms; and P. ocellatus, (Gthr.,) Admiialty Islands, 152 fathoms.
