Form. — Depth one-fifth of the entire length. Head about one-fourth of the same, rather large, with 

 the cheeks and gills a little inflated. Profile falling gently from the nape : the crown scarcely 

 at all convex. Gape reaching to beneath the anterior part of the eye. Lips thick and fleshy, 

 and partly reflexed, much resembling those of a Labrus. Lower jaw projecting a little beyond 

 the upper, and inclining upwards to meet it. An outer row of strong conical teeth in each 

 jaw, with a velutine band behind ; the band broad above, but very narrow below. A largish 

 triangular patch of velutine teeth on the vomer, and a smaller one on each palatine. Tongue 

 free and fleshy, smooth. Eyes moderately large, their diameter one-fifth the length of the 

 head ; high in the cheeks, reaching to, but not interrupting, the line of the profile. The super- 

 ciliary tentacles consist each of eight short bristles, all separate to the root, but forming toge- 

 ther a closely compacted series : two on the nape, of the same length as them, are broad and 

 palmated, the upper half only being divided into eight or ten slender filaments : two on the nos- 

 trils are similar to those on the nape, only somewhat smaller. 



The dorsal commences at the nape, a little behind the nuchal appendages, and has the 

 spinous portion long, and of nearly uniform height, but no where very high. The spines 

 increase very gradually in length as they advance, the first being the shortest : in the middle 

 of the fin, they equal about one- third the depth of the body, or hardly so much : above each is 

 a short filamentous tag, as in the Labridce. The soft portion is nearly twice the height of the 

 spinous. A small interval between the termination of this fin and the caudal. The anal com- 

 mences under the twelfth spine of the dorsal : its own two spines are very short, and not half 

 the length of the soft rays, which last are not quite so long as those of the dorsal : the mem- 

 brane between each of the rays is deeply notched. This fin terminates a very little before the 

 dorsal. The caudal, when expanded, appears slightly rounded. Pectorals broad and rounded, 

 about one-fifth of the entire length. Insertion of the ventrals directly underneath the commence- 

 ment of the dorsal, and both in a vertical line with the posterior margin of the preopercle. These 

 last fins are contained nearly nine times in the entire length. 



Body covered with moderately small scales ; the length and breadth of each scale nearly 

 equal, with the basal portion nearly covered by an irregular fan of strise, eighteen or twenty in 

 number. Head naked, but the crown and upper part of the snout studded with papillae, termi- 

 nating upwards in pores. There are rows of minute scales between the rays of the dorsal for 

 about one-third of their height ; also at the base of the caudal and pectorals, but none on the 

 anal. The lateral line commences behind the upper angle of the opercle at one-fourth of the 

 depth ; when opposite the eleventh ray of the dorsal, it begins to bend downwards, and con- 

 tinues falling till opposite the seventeenth ray, when it gets to the middle of the depth ; from 

 that point it passes straight to the caudal.
