102 BULLETIX OF TIIH 



PLEURONECTID^. 

 1. Aphoristia nebulosa, new species. 



The extreme length of tlie type is 85 milliiueteis. The body is mther shni- 

 (Icrcr ihcin in other species of the geuus ; its greatest height (18 iiuu.) is con- 

 tiiiiifd 42 times iu the extreme length. The scales are small, rough, about 1:^0 

 ill a longitudinal series ; about 50 iu a transverse series. Jaws and snout 

 scaleless. The length of the head (15 mm.) is contained 5§ times in tot;il 

 length. The length of the snout (3 mm.) is \ that of the head. The eyes are 

 small and close together, being separated by only a single row of scales ; the 

 upper eye is very slightly in advance of the lower. The tubular nostril is 

 directly in front of the lower eye, and a little nearer to it than to the ti[) of 

 snout. The length of the eye (2 mm.) is contained 7-h times in length of head. 

 The angle of the mouth is about in a vertical through the anterior margin of 

 tlie lower pupil. Teeth feeble, very slender, and rather closely placed, ap- 

 parently ef^ually developed, on the two sides. 



The dorsal fm begins at a point slightly licliind the eyes ; it is connate with 

 the caudal, and contains 119 rays to the middle of the base of the caudal ; the 

 rays about the middle of the fin are the longest, their height being a little 

 more than one third that of the body. 



The distance of the anal from the snout (20 mm.) is contained 4} times in 

 extreme length ; the longest rays are about the middle of the fin, their length 

 (6 mm.) equalling twice tliat of the snout. The anal is connate with the cau- 

 dal, and contains 107 rays, counting to the middle of the base of the latter fin. 



The median caudal rays are longest, their length (C nmi.) equalling twice 

 that of the snout. 



Pectorals none. 



The distance of the ventral from the snout (15 mm.) is contained 55 times 

 in extreme length . The ventral is separated from the anal by an interspace 

 twice as long as the eye. The number of ventral rays is five, the longest of 

 them being one third as long as the head. 



The vent is near the origin of the anal. 



Color grayish, everywhere mottled with brown. The median keel on the 

 scales daik and prominent. 



Radial formula : D. 119 ; A. 107 ; V. 5 ; P. none.

NOTOSEMA, new genus. 



Four specimens of a new genus and species, belonging to the Flounder fam- 

 ily, were dredged by the Blake at Station 313, off Charleston, S. C, at a depth 

 of seventy-five fathoms. 



In general appearance and size this species resembles ParaliclilJujs rjuadro-
