the opercle, the lower one long and projecting posterior to the margin of that 

 bone. A stout one may be observed on the humeral region, one on the infra- 

 orbital, three on the margin of the preopercle, and a longitudinal row of irregu- 

 larly disposed ones along the cheek. The lower jaw is slightly longer than the 

 upper, and the tip of the maxillary extends as far back as the hinder border of 

 the eye. Fine scales envelop the basal portions of all the fins except the ven- 

 trals, and cover all parts of the head except the jaws and the lower half of the 

 maxillary bone. Minute filaments are observed on all parts of the fish, being 

 more numerous on the upper anterior third of the body. The dorsal and anal 

 fins are small, the formqr commencing above the origin of the latter line. The 

 spiuy portion of the dorsal is very low, gently arched, and constitutes nearly 

 two-thirds of the fin. The soft portion of the anal fin is very narrow and 

 rounded off. 



The head and anterior half of the body is greyish, passing into light carna- 

 tion beneath, and obscurely clouded with dusky. The posterior half of the body 

 is dusky black, which fades into pink beneath, maculated with small darker 

 spots. Caudal trunk, pink. Two large dusky black spots on the anterior dorsal 

 region. Irides greenish-yellow. Fins pinky-red, the spiny dorsal mottled with 

 dusky, and the other fins dotted with pinky-brown, and a bar of the same color 

 on the caudal base. 



Length. 4 inches. 



Habitat, Sandwich Islands. 



Remarks. — The scaly head, small dorsal and anal fin will readily distinguish 

 this beautiful species.

The greatest depth, which occurs beneath the origin of the dorsal fin, is about 

 one-fourth of the total length, and the greatest thickness is just half of the above 

 mentioned depth. The head, which comprises a little more than one-fourth of 

 the whole fish, presents a slight concave depression above the eyes. The preop- 

 ercular serrations are very small. The eyes are sub-circular, their greatest 

 diameter entering nearly six times in the length of the head, and twice in advance 

 of their own orbit. The hinder tip of the maxillary reaches a vertical, passing 

 through the center of the eye. Twelve longitudinal rows of scales may be 

 enumerated between the lateral line and the vent, ten rows on the side of the 

 caudal trunk, and the median longitudinal row on the body contains thirty 

 scales. The lateral line, which passes over thirty-three scales, consists of slightly 

 branched tubes. 



The dorsal fin extends over a base equal to half the length of the fish, caudal 

 fin excluded. Its soft portion falls slightly short of one-third of the whole fin. 

 The anal fin, which is nearly half as long as the dorsal, has its hinder termina- 

 tion slightly more posterior. The acumiuately pointed veutrals, when closely 

 appressed to the abdomen nearly reach the anal fin. The large caudal has its 

 posterior upper and lower angles considerably prolonged and pointed.
