GOBITJS PULCHELLXJS. 



Form elongate. Height of the body four and three-quarter 

 times in the total length; head three and a-half times in same. 

 The first dorsal is rounded, with six rays ; the first shorter than 

 the second, the third rather longer than the others, and the 

 following go on decreasing ; the second dorsal has twelve rays. 

 In both, the rays are much longer than the membranes. The 

 caudal is rounded, with twelve rays ; anal with one spine and 

 nine rays, formed like those of the dorsal ; ventrals large, united, 

 pointed, with their lower rays much longer than the others. 

 Pectorals rather large, extending to nearly the end of the first 

 dorsal, of fifteen rays. Scales large ; about twenty-three of them 

 on the lateral line ; eye moderately large, ^placed on the upper 

 surface of the head. 



Greneral colour of a light grey, with the edges of the scales 

 brown ; lower parts of the body opal and white ; head marbled 

 with white spots ; operculum covered with very minute black 

 dots ; front part of the head rather yellow. Three large round 

 black spots on each side of the body — one opposite to the begin- 

 ning of the second dorsal, the other to its end, and the third at 

 the root of the caudal. There are also some undefined, trans- 

 verse, white stripes on the sides of the body. Dorsal hyaline, 

 marbled with brown spots, a black spot covering nearly the 

 exterior half of the first membrane. Second dorsal with its rays 

 spotted with brown, and yellow at their end. Caudal with the 

 rays also spotted with brown, the spots forming five or six transverse 

 lines of that colour. Anal large, white, with the rays yellow at their 

 base, and black to almost their full extent ; ventrals black, with 

 their base white ; pectorals rather yellow, marbled with white ; 

 their rays covered with very small, black dots. Eye yellow, with 

 orange spots on its exterior edge.
