 correct form, and that "Ciivior's name may liavc resulted from a 

 typographical error.'' 



The priority of the second edition of ihe Regne Animal and the early 

 volumes of the Hist. Nat. Poiss seem to have been juggled by a num- 

 ber of A\Titers, causing confusion in the selection of some names, so 

 that it is hoped the above remarks may conduce to solve the problem. 

 As an instance Gempylus will thus be seen to replace Lemnisoma, if 

 identical.

 applied to these fishes, meaning a slave, with reference to the fish being 

 under the lash of the long dorsal spine.)

This differs from subgenus Eudulus chiefly in the above character.

 Type, Xo. 13,675, A. N. S. P. Southern coast near Pensacola. 



Width of head 2 in its length ; interorbital space 7 in head measured 



from tip of upper jaw. Body compressed, edges rounded, and caudal 



peduncle compressed. Head compressed, its sides swollen below and 



becoming more narrow above. Snout much broader than long. 



Bands of small teeth in jaws, outer canines a little better developed 



than inner, and largest in front of upper jaw and on sides of mandible.

finely ctenoid. Interorbital space, mandible and branchiostegal region 



naked. Tubes in lateral line simple. Color in alcohol deep brownish, 



fading paler on lower surface of body and fins. Above lateral line 



about 5 narrow deeper brown lines than body-color parallel with coiu'ses
