 1. Aphoristia nebulosa, new species. 



The extreme length of the type is 85 niilliiueters. The body is rather slen- 

 derer than in other species of the genus ; its greatest height (18 mm.) is con- 

 tained 41 times in the extreme length. The scales are small, rough, about 1^0 

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

 scaleless. The length of the he;ul (15 mm.) is contained 55 times in tot.il 

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

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

 upper eye is very slightly in advam^e of the lower. The tubular nostril is 

 directly in front of the lower eye, and a little nearer to it than to the tip of 

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

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

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

 parently equally developed on the two sides. 



The dorsal fin begins at a point slightly behind the eyes ; it is connate witli 

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

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

 more than one third that of the body. 



Tlie 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 

 (() mm.) equalling twice that 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 (6 iimi.) equalling twice 

 that of the snout. 



Pectorals none. 



The distance of the ventral from the snout (15 mm.) is contained 5§ 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 dark and ]iroTninent. 



Radial fonnula : 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 Parallclithijs qiuulro-
