Head 4 to 4^; depth 5 to 51; eye 3 in head; scales 5^50 to 54-X. D. 

 X-13; A, II, 7. In form much resembling raciUchthys ::onaUf), but the 

 body slenderer and less compressed, and the anterior profile of head more 

 declivitous, the mouth being on a level with lower portion of ba^e of pec- 

 torals. Mouth small, horizontal, subinferior, the lower jaw included ; 

 maxillary reaching vertical from front of pupil, 3| in head. Eye rather 

 large, high up on sides of head, its diameter much greater than length of 

 snout. luterorbital width half vertical diameter of orbit; parietal region 

 narrow, smooth, rather strongly arched. Opercular spine little developed. 

 Gill membranes broadly joined across the isthmus. Premaxillaries tech- 

 nically protractile, the upper lip everywhere separated by a fold from 

 the skin of the forehead; they are, however, very little movable. Verti- 

 cal fins small, the paired fins greatly developed; spinous and soft dorsals 

 separate, nearly equal in height and extent; the longest dorsal spine 

 half length of head, the spines all slender and weak ; first anal spine 

 longer and stronger than the second, slightly longer than snout; caudal 

 fin emarginate, less than length of head ; i^ectorals much longer than 

 head, reaching beyond tips of ventrals to vent, their length nearly i 

 that of body ; ventrals about as long as head. Scales ctenoid ; lateral 

 line complete, not decurved; head naked, or with a few scales on oper- 

 cles ; nape completely scaled ; breast and a long strip behind ventral 

 fins naked, only the posterior half of ventral region scaled over; no 

 enlarged humeral scale. Color : Body very dark green ; back with 7 

 light cross bars, usually very distinct ; ventral region light, the lower 

 half of sides marked with light and dark greenish, these markings 

 showing a tendency to form bars, usually alternating with those on 

 back; top of head dark, the sides light greenish ; a broad dark bar from 

 eye to tip of snout, 1 below eye, and a broad dusky area covering parts 

 of opercle, preopercle, and cheek; a dark bar in front of pectoral fin 

 and several transverse series of dark spots on under side of head ; fins 

 all conspicuously marked with broad bars of light and dusky greenish ; 

 a black humeral spot; females show traces of this plan of coloration, 

 but are more uniformly dusky greenish, the lighter marking much less 

 conspicuous. Length 2 inches ; a small, odd looking little fish. Southern
