Sixteen longitudinal series of scales between the second doi'sal and 

 the anal fin. The extent of the snont is one-third of the length of 

 the head. Eye small, one-seventh of the length of the head. The 

 height of the body is contained five times and three -fourths in the 

 total length, the length of the head four times and a half. The in- 

 terorbital space is flat, and its width equals the diameter of the eye. 

 Teeth in a very narrow band in the upper jaw. The upper jaw is 

 longer than the lower, and the maxillary does not extend to the ver- 

 tical from the orbit. The distance of the first dorsal from the eye is 

 considerablj' more than that of the snout from the prteoperculum. 

 Scales on the nape much smaller than those on the sides. The ven- 

 tral terminates at a great distance from the vent, and has a broad 

 basal membrane. Dorsal fins lower than the body. Groimd-colour 

 green on the back, with metallic reflexions on the sides, irregularly 

 spotted and dotted with dark brown ; two oblique streaks from the 

 eye to the lip ; dorsal and caudal rays with brown dots, forming lon- 

 gitudinal stripes on the former, and transverse ones on the latter ; 

 ventrals and anal white.

This species is so closely allied to the West Indian G. banana, that 

 it requires a very close examination to detect difl'erences by which 

 both may be distinguished, whilst, on the other hand, it is very 

 distinct from the East Indian G. grammepomus. Its most cha- 

 racteristie feature appears to be the snout, which is comparatively 

 shorter than in G. hanami ; yet some specimens of the latter approach 

 it very closely also in this respect. 



115. Gol)ius mexicanus. 

 D. 6 I 11. A. 11. L. lat. 76-82. 

 Twenty-four series of scales between the second dorsal fin and the 

 anal. The height of the body is contained seven times and a half in 

 the total length, the length of the head four times and four-fifths. 

 The head is fiat superiorly, as broad as high, its width being nearly 

 one-half of its length. Snout elongate, with the upper profile 

 oblique ; cleft of the mouth horizontal, the iipper jaw being rather 

 the longer. Canine teeth none ; teeth of the outer series enlarged. 

 The maxiUary extends to the vertical from the anterior margin of 

 the eye. The width of the interorbital space equals the diameter of 

 the eye, which (in matui'e specimens) is one- eighth of the length of 

 the head. The head is naked ; scales ctenoid, those on the nape and 

 on the anterior part of the body very small. The distance of the
