Specimens of this Ammodytes, which in my Report I considered the A. tobianus, were 
sent to Mr. Yarrell, who writes me, —‘‘I feel quite satisfied that it is distinct from both 
the ¢obianus and lancea.’’ Never having seen the foreign species, I cheerfully prefix Dr. De- 
kay’s specific name, after this careful comparison by the distinguished British ichthyologist. 
2. Ammodytes vittatus, Drxay. 
Body oblong, subcompressed, slender. Greenish olive above, with a broad silvery band 
along the sides, which is margined above with blackish; belly white. Seven projecting 
spinous processes before the dorsal fin.

LOPHOBRANCHII. 
Gills, instead of being, as usual, pectiniform, are divided into little round 
tufts, dispersed in pairs along the branchial arches.

Body mailed with transverse angular plates. Opercle large ; branchial 
opening very small, and formed by a membrane which only exhibits vestiges 
of rays. Dorsal single. No ceca ; with an air-bladder.

in parallel lines ; head long ; both jaws produced, united, tubular ; no ventral 
fins. Males with a pouch for the reception of the female roe.

Olive-brown, with darker-colored blotches or bars. The posterior portion of the body is 
darker than the anterior. Beneath, anterior to the vent, of a beautiful golden-yellow ; por- 
tion back of vent nearly white. Body, anterior to vent, heptangular ; in front of posterior 
extremity of the dorsal fin, hexangular; posteriorly quadrangular. Nineteen transverse
