The dorsal flu begins ou the snout upon the blind side and in advance 

 of the eyes. Its greatest height (15""") about equal to length of mandi- 

 ble. It is composed of 93 simple rays. 



The anal begins under the axil of the pectoral, its longest ray equal 

 to or slightly exceeding half the distance of its anterior ray from the 

 snout. It is composed of 73 simple rays. 



Color light-brownish gray ; a dark blotch, as long as the eye, on the 

 anterior rays of the analj another of lighter hue at the junction of the 

 curved and straight portion of the lateral line. A few obscure blotches 

 on different parts of the body. The caudal is subsessile, composed of 

 17 rays ; its length (24™"^) a little less than half the height of the body, 

 and equal to lengtli of head without snout. 



The pectorals are inserted considerably below the origin of the lateral 

 line, and close to the gill-opening. That on the colored side is composed 

 of 11 rays, its length (19™™) nearly one-sixth of the total length; that 

 of the bhnd side composed of 7 or 8 rays, the longest (28™™) almost as 

 long as the .head. 



The ventral consists of 6 rays. The length of the ventral of the eyed 

 side (11™™) is about one-third that of the blind side (34™™). Females 

 have the ventral of the blind side not enlarged, 



Etropus rimosus, n. s. 



Length of type (to base of caudal) 100 millimeters. Body pear- 

 shaped, its height (54™™) slightly exceeding half its length. 



Scales large, strongly pectinated ou both sides, about 41 in the longi- 

 tudinal series, 12 above and 14 below the. lateral line. Lateral line 

 equally developed on both sides, very slightly curved above the pec- 

 toral. Head entirely covered with scales. Numerous small super- 

 numerary scales between the normal scales covering their surface. 



Length of head (24™™) slightly less than one-fourth of the total length. 

 Snout very short, its length (3™™) 8 times in that of head. Mouth 

 very small, its cleft less than diameter of orbit, its angle reaching about 

 to vertical through anterior margin of lower eye. 



The length of the maxilla (5™™) somewhat less than one-fourth that 

 of head. Length of mandible considerably more than one-third of the 

 same length. 



Teeth well developed on blind side in both jaws, also on the colored 

 side of lower jaw in front. 



Eyes moderate (7™™), their diameter contained nearly 3^ times in 

 length of head, placed in the same vertical, the upper eye close to the 

 dorsal profile, and separated from its mate by a space less than one- 

 third of its own diameter. Interorbital ridge low. 



Nostrils in line with the interorbital ridge, each in a short tube, the 

 posterior being the larger. The anterior nostril is equidistant from the
