The height of the body is contained four times in the total length (without caudal), 

 the length of the head thrice and a fourth. Head rather elongate, much depressed 

 anteriorly, the snout being somewhat longer than the eye, which is one-fourth of the 

 length of the head, and more than one-half of the width of the interorbital space. Jaws 

 equal in length anteriorly. The origin of the dorsal fin is midway between the ex- 

 tremity of the caudal and the praeoperculum, corresponding to the eighteenth scale of 

 the lateral line and to the middle of the anal. Pectoral fin scarcely extending beyond 

 the root of the ventral, which reaches the anal. There does not appear to exist a 

 conspicuous difference between the sexes as regards the fins. 



Colour in spirits. — Brownish, with three or four indistinct, serrated, dark longitudinal 

 bands. Sometimes a black line across the base of the middle dorsal rays. 



Colour in life. — Yellowish olive, with about seven longitudinal rows of red spots 

 (between the serrated bands mentioned above), corresponding to the series of scales; 

 opercles with four similarly coloured lines ; vertical fins spotted and reticulated with 

 brown. 



Length from 2 to 3| inches.
