Head 3; depth If; D. XII, 23; A. Ill, IT; P. 1, 16; V. I, 5; scales 

 a])out 4-44-24:. Body deep, compressed , the scales enlarged on the sides, 

 snnill on the head, and becoming- very small on the basal portion of 

 the soft dorsal, anal, and the caudal. Head rather deep; eye 2i in the 

 head and nuich larger than the interorbital space; snout nearly straight 

 above, shorter than the eye, pointed and projecting; mouth i-ather 

 small, the maxillary reaching nearly to the anterior nostril; nostrils 

 close together in front of the eye; teeth small and tine in both jaws; 

 interorbital space convex; gill-opening large, the rakers small and not 

 numerous; gill-membrane very narrow and free from the isthmus; 

 dorsal high in front, graduated to the fourth spine, which is very long, 

 attenuated, and furnished with a tilament, the total length exceeding 

 the entire length of the tish; the fifth spine is longer than the third; 

 middle of soft dorsal elevated; tirst anal spine short; soft anal with the 

 anterior raj's elevated into a sharp ana'le, then rapidh^ decreasing to 

 the last, which are very short; pectoral low, moderate, aliout equal to 

 the ventral spine; ventral under the pectoral very long, reaching 

 to the middle of the base of the anal, and the tip of the ventral spine 

 not extending to the origin of the anal; caudal moderate, the edge 

 somewhat rounded. Lateral line high, very nuich arched, and extend- 

 ing down on the caudal peduncle. Caudal peduncle compressed, and 

 equal to the eye. 



Color in alcohol, dark above, head silvery white; the snout dark 

 brownish and a dark brown band from one e^^e to the other across 

 the forehead; a dark brown band from the tirst dorsal spines down 

 the sides including the posterior part of the gill-opening, and the 

 base of the pectoral to the belly, w^here it becomes broader and 

 joining the one from the opposite side of the bod}^; a white band of 

 similar width behind the one just described, becoming very broad 

 below, so that it extends over the tirst half of the anal tin; there is a 

 second broad black band arising behind the tip of the tifth dorsal 

 .spine and extending obliquely across the body so as to include the 

 posterior half of the anal tin; behind this the rest of the ))odv is pale 

 and silvery; the dark liands where they extend on the dorsal and anal 

 tins, together with the entire ventral tins, are black. Length, 2| 

 inches. In a very young specimen the profile of the body above and 

 in front is more obliquely inclined, and the brown bands are broader, 

 the posterior occupying all the rest of the back and caudal peduncle; 

 the large nuchal scales are w^ell developed. Hei'e described from 

 Wakanoura examples.
