(■without caudal), and its width between the prseopercular spines is more than one-half of 

 its length. All the bones on the upper surface, and the scales covering its sides, are 

 rough. The space between the eyes is concave, its width being one-half of the vertical 

 diameter of the eye. Superciliary edge serrated ; ridges with distant spines along the 

 infraorbital and above the operculum, the central ridges of the crowTi of the head being 

 rather obscure. Opercular ridge not serrated. Three spines at the angle of the prse- 

 opierculum, the lower of which is the smallest, the upper the longest, but only half the 

 length of the eye. Only the foremost part of the lateral line is spiny. Ventral fins 

 reaching to the anal. Greyish, with black dots on the trunk and operculum. The spinous

D. 6/11, A. 11, L. lat. 26. The height of the body is contained four and a half 

 times in the total length (without caudal), the length of the head thrice and three-fourths. 

 Snout obtuse, as long as the eye, the diameter of which is more than one-fourth of 

 the length of the head. Eyes very close together ; mouth oblique, -with the jaws sub- 

 equal in front, reaching to below the front margin of the eye ; a very small canine tooth 

 on each side of the lower jaw; head and occiput naked, but nape covered with small 

 scales. A wide porus in front and behind the interorbital space, and two others behind 

 the eye ; they are the openings of the muciferous channels. Seven longitudinal series of 

 scales between the second dorsal and the anal. The ventral fin terminates at some distance 

 from the vent, which is midway between the root of the caudal and the prseoperculum. 

 Dorsal fins rather lower than the body ; caudal shghtly pointed, as long as the head. 

 Light brownish olive, with a series of five brown spots along the lower half of the body, 

 the last being on the root of the caudal and the most distinct ; a triangular black spot 

 occupies the lower angle of the operculum ; gill-membrane on the tlu'oat blackish. 



Small as this species is, it is adult, a female having the ovaries fully developed. 

 Length of specimen, 2^ inches. Yokohama Bay ; 15 fathoms. Inland Sea of Japan.
