DISCUSSION OF SPECIES AND THEIR DISTRIliUTlON. 437 



NOTOSEMA, Goode and Bean. 



Notosema, Goodb and Bean, Hull. Mns. (Jouip. 7,i<i\\., x, Issii. 



Sinistral pleurouectoids witli elli|>tital body and ]it^duiicnlatp catnlal fin. Monti, mod- 

 erate in size, aud beiieatli the central axis of the body. Kyes larye upon left side, dose 

 together, tlie upper one nearly enc^roaching upmi the jiiolile, the lower slightly in advance 

 of the upper. Teeth in single series in the jaws, about equally developed upon each side 

 much largest in front; absent on vomer and palatines. Pectoral fins somewhat unequal' 

 that upon the blind side about three-fourths as large as its mate. The dorsal flu com- 

 mences slightly l)ehiu<l the anterior margin of the ui)per eye, and tlie first eight rays are 

 separated into a distinct sul)divisi(jn of the fin, several of tliem being much prolonged. 



Caudal fin pedunculate, rounded jmsteriorly. Sinistral ventral much elongated. Scales 

 small, strongly ctenoid on colored side of body. Lateral line prominent, strongly arched 

 over the pectoral, alike on both sides. Gill rakers moderately numerous, rather stout, sub- 

 triangular, i)ectinate posteriorly. Psendolirancliia- well developed. Yertebrie 35.

The height of the body is containcil twice in its total length, without caudal, and m 

 equal to twice the distance of the origin of the ventral from the snout. The height of the 

 caudal peduncle is one-ninth of the standard body length. 



The length of the head is two-sevenths of the standard leugtli, and three times the 

 diameter of the eye. Width of interorbital area almost impei-cei)tibie. Mandible reaching 

 to middle of pupil of lower eye, its length equal to half that of thi' head. Upper jaw con- 

 tained 2^ times in length of head. 



The dorsal fin, beginning almost over the anterior margin of the eye, is comjiosed of 

 about 68 rays, the longest'of which are the second and third, which are contained twice in 

 the greatest height of the body, and which are almost twice as long as the length of the 

 base of the triangvdar division of the fin to wliich they belong. 



The anal fin is made up of ,54-56 simph^ lays, of which the ]iosterior ones are largest, 

 as they are also in the maiu portion of the dorsal. It begins close to the vent, at a dis- 

 tance from the .snout equal to the length of tlie elongated sinistral ventral. 



The caudal is pednnciilate, its middle rays somewhat elongate, giving it a wedge-shaped 

 outline. 



The pectoral of the colored side is subtriangular, its length <<int;iined live and one- 

 half times in the standard length. 



The ventrals are composed of six rays, that njion the colored .side nnieh jnoduced in 

 its anterior portion, its length more than three times that of its mate. 



Radial formula: D. 6!); A. .56; P. 11; V. 6; B. 7. Lateral line 48 (in .straight portion). 



Color on the left side purplish brown, spc<'kled with dark brown, and with three large 

 ocellated subcircular spots, nearly as large as the eye, with white center, dark iris, narrow 

 light margin, aud a brown encircling outline. They are ananged in the form of an isosceles 

 triangle, the spot marking the apex being ui)on the lateral line, near the base of the cau- 

 dal peduncle, the others distant from the lateral line, on either side, a space equal to tiieir 

 own diameter.s, the lower one nearly reached by the tip of the elongate ventral. On the 

 blind side white. Fins blotched with dark brown. 



The Blale obtained 4 specimens from station cccxiil, o(f Charleston, S. C., in 32° 31' 

 50" iS". lat., 78° 45' W. Ion., at a depth of 75 fathoms, and a single individual from station 

 CLXVIII, in 23° 13' N. lat., 81)° lO' W. Ion., at a dei)th of 84 iathoms. Examples were also 

 secured l)y the Allxitross from station 2311, in .32'3 55' N. lat., 77° 54' W. Ion., at a depth of 

 79 fathoms; fiom station 2313, in 32° 53' N. lat., 77° 53' W. Ion., at a depth of 99 lath-
