total length (without caudal). Eight lobate incisor3 in the upper 

 jaw, and ten in the lower. Anterior profile of the snout slightly 

 concave. The distance of the nostril from the edge of the upper 

 jaw is two thirds of the length of the head. Dorsal and anal fins 

 rounded behind; caudal deeply forked, with the lobes pointed. 

 Deep black ; a ring round the lower jaw, the opercular membrane 

 and the outer ventral ray bluish. Hind margin of the caudal with 

 a lighter-coloured crescent. 



One specimen, 3^ inches long (no. 56), from the Godeffroy Mu- 

 seum ; it was obtained at Savay (Samoa Islands).

The height of the body is contained twice and one fifth in the 

 total length (without caudal), the length of the head thrice and a 

 half. Abdomen not compressed into a ridge ; ventral fins received 

 in a groove. The eye occupies nearly the middle of the depth of 

 the head ; its diameter equals the length of the snout, and is one 

 fourth of that of the head. Jaws with a series of very small teeth. 

 The vomer and tongue are armed with a narrow band of minute 

 teeth ; no palatine teeth. Maxillary hidden below the praeorbital, 

 and extending to the front margin of the orbit. Pectoral fin rather 

 longer than the head, and extending considerably beyond the origin 

 of the anal. Ventral fin two fifths as long as the pectoral. Caudal 

 fin deeply forked. Light brownish, with a silvery tinge ; a blackish 

 stripe along each series of scales. Fins black, except the pectoral -, 

 inside of the mouth and gill-cavity flesh-coloured. 



One specimen, 6 inches long, has been sent from Manado by Dr. 

 A. B. Meyer.

The length of the head is two sevenths of the total (without cau- 

 dal), its width between the praeopercular spines is contained once 

 and three fourths in its length. Upper surface of the head smooth, 

 without spines, except a minute one in front of the eye. Praeoper- 

 cular spines short, subequal in length, or the lower somewhat the 

 longer. The teeth of the maxillary are villiform, forming a broadish 

 baud with two pairs of distinct canine teeth behind on the side of 

 the symphysis. The mandibulars and palatine bands are much 

 narrower, with a series of longer conical teeth. Vomerine band con- 

 tinuous, crescent-shaped, narrowest in the middle, broadest towards 

 each extremity, where also some larger conical teeth are mixed with 

 the villiform teeth. Interorbital space but slightly concave, scaly, 

 its width being equal to the diameter of the eye, which is contained 

 twice and one third in the length of the snout. Eye without tentacle. 

 The isolated dorsal spine short and stiff. Upper parts nearly uni- 

 form blackish ash ; dorsal fins without spots, transparent ; caudal
