triangular, nearly as broad as long : posterior part of the head 

 densely granulated, as also are the edges of the longitudinal 

 groove to opposite the hinder margin of the eye ; there is also a 

 granulosa patch above the base of the pectoral. The maxillary 

 barbel extends backwards to the base of the pectoral fin, the 

 external mandibular not quite so far. Teeth in the lower jaw in 

 two small angular patches, obtusely conical, and villiform ; in the 

 upper in two similar oval patches : palatines with two small oval 

 patches cf villiform teeth anteriorly. The dorsal fin is as high as 

 the body, its spine as long as the head behind the posterior nostril ; 

 it is strongly granulated in front for two-thirds of its height, the 

 remaining third and the entire back being weakly serrated ; the 

 length of the base of the adipose dorsal equal to that of the rayed : 

 pectoral spine very strong, considerably longer than the dorsal 

 spine, slightly roughened on the outside and strongly denticulated 

 on the inside ; they almost reach to the ventrals, which on their 

 part just touch the anal fin : caudal deeply forked, the upper lobe 

 the longer. There are numerous small round wart-like pro- 

 tuberances irregularly scattered over the sides of the body. 

 Colors, steel-blue above, silvery below; a faint white spot on the 

 occiput, and another in the posterior angle of the base of the 

 rayed dorsal : base of the pectoral inside pale blue.

We have much pleasure in dedicating this distinct species to 

 Mr. Froggatt, on whom the whole burden of collecting the 

 zoological specimens obtained during the late expedition of the 

 Bonito seems to have fallen.
