DISCUSSION' OF SPECIES AND THEIB DISTRIBUTION. 437 



NOTOSEMA, Goode and Beau. 

 XotoHt -inn, lliionn :unl Be.vx, Bull. Mum. (' p. Zoo]., \. 1883. 



Siuistral pleuronectoids with elliptical bodj and pedunculate caudal tin. Monti, i 1 



erate in size, and beneath the centra] axis of the body. Eyes large upon left side, close 

 together, the upper one nearly encroaching upon the profile, the lower slightly in advance 

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

 Uiuch largest in front; absent OU vomer anil palatines. Pectoral tins somewhat unequal, 



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



indices slightly behind the anterior margin of the upper eye, and the first eight rays are 

 separated into a distinct subdivision of the fin, several of them being much prolonged. 



Caudal tin pedunculate, rounded posteriorly. 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, pectinate posteriorly. Pseudobranchise well developed. Vertebra? '■'•'>. 



NOTOSEMA DILECTA, <; .1: ami Bean, t Figures 365 A, B,362, young.)

 Ancylopsetta dilecta, Jordan, Cat. Fish. N. America, 1885, 134. 



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

 equal to twice the distance of the origin of the \ entral 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 length, and three times the 

 diameter of the eye. Width of interorbital ana almost imperceptible. Mandible reaching 

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

 tained LM times in length of head. 



The dorsal tin, beginning almost over the anterior margin of the eye. is composed 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 triangular division of the tin to which they belong. 



The anal fin is made up of 54-56 simple rays, of which the posterior ones are largest, 

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

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



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

 outline. 



The pectoral of the colored side is subtriangular, its length contained live and one- 

 half times in the standard length. 



The ventrals are composed of six rays, that upon the colored side much produced in 

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



Radial formula: D. 69; A. 56; P. 11; V. 6; B. 7. Lateral line 48 (in straight portion). 



Color on the left side purplish brown, speckled with dark brown, and with three large 

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

 ligh.1 margin, and a brown encircling outline. They are arranged in the form of an isosceles 

 triangle, the spot mat king the apex being upon the lateral line, near the base of the can 

 dal peduncle, the others distant from the lateral line, on cither side, a space equal to their 

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

 blind side white. Fins blotched with dark brown. 



The Blake Obtained 4 specimens from station CCCXIII, off Charleston. S. ('.. in 32 31' 

 50" N. hit., 78° 45' W. Ion., at a depth of 7."> fathoms, and a single individual from stal ion
