Genus Umbrina Cuvier. 



104. Umbrina macroptera (Bleeker). 



No. 8iioa, C. M. One small specimen, four inches long. The 

 barbel is small, less than one-fourth the diameter of the eye. Pre- 

 opercle crenulated. Outer premaxillary teeth somewhat enlarged. 

 Fine scales extend upward over approximately the basal half of the 

 soft dorsal membrane. The only other species described, which has 

 so short a barbel, is U. siniiata, a conspicuously banded species. 



Family MULLID^. 

 Genus Upeneus Cuvier. 



105. Upeneus macronemus (Lacepede). 



No. 81 lie, C. M. One specimen of this well-defined species, show- 

 ing all the typical markings. 



106. Upeneus dispilurus (PJayfair). 

 No. 8112a, C. M. Two specimens. 



Genus Upeneoides Bleeker. 



107. Upeneoides vittatus (Forskal). 



No. 8146c, C. M. Several specimens with the oblique caudal bars 

 more or less evident. Teeth on jaws, vomer, and palatines. 



Family POLYNEMID^. 



Genus Trichidion Klein. 



{Polydactylus Lacepede.) 



If the genera of Klein, revived by Miiller and others in " Der Neue 

 Schauplatz," 1777, are eligible, as claimed by Garman, Trichidion 

 must displace Polydactylus. 



108. Trichidion plebeium (Broussonet). 



No. 8113a, C. M. A single large specimen taken. It has been 

 compared with a specimen from Samoa (type-locality Tahiti) and no 

 specific difference could be appreciated. In the Samoan specimen the 

 stripes are more pronounced, though the same in number and position; 

 the color of the fins a little darker; the snout somewhat sharper. All 

 of these differences were slight.
