distinct. In many respects, our specimen agrees witii C. equisctis, but the figure (pi. 

 267), exliibits a different species. Under these circumstances, I shall, until another oppor- 

 tunity presents itself of examining a more recent specimen, consider it as hitherto undescribed. 



{EXTRALIMITAL.) 



C. sucri. (Cuv. et Val. Vol. 9, p. 302.) Height of the anterior rays of the dorsal to its length, 

 as one to seven and a half Dorsal fin with sixty-four, and anal with twenty-six rays. Length 

 three feet. Coast of the United States. 



CxENUS LAMPUGUS. Cuvier. 



Head not tenninating in a rounded crest above. Dorsal subequal throughout its length, not 

 elevated in front. 



Obs. This genus was first clearly indicated by Cuvier, from Coryphana, with which it is 

 otherwise closely allied. 



THE SPOTTED LAMPUGUS. 



Lampcgus pcnctdlatds. 

 PLATE XI. FIG. 31. — (CABINET OF TEE LYCEUM.) 



Le Lavipuge ponctue, L. punctnlatus. Cuv. et Val. Hist, des Poiss. Vol. 9, p. 327. 



Characteristics. The last ten or twelve rays of the dorsal somewhat elevated. A series of 

 rounded distant blackish dots along the base of the dorsal ; others irregu- 

 larly distributed on the sides. Length two feet. 



Description. Body elongate, compressed. Length of the head rather less than one-eighth 

 of the total length. Height of the body at the pectorals one-eighth, and at the base of the 

 caudal one-twentieth of the total length. Its facial outline slightly and equally curved from 

 the origin of the dorsal to the point of the upper jaw. Scales small, oblong, deeply imbedded ; 

 largest at the posterior end, and gradually attenuated at their radical margin (see figure). The 

 free extremity rounded, with deeply impressed concentric strife. Lateral line waving irregu- 

 larly above the pectorals, thence straight. Several series of long acute spicular scales along 

 the anterior part of the dorsal fin (see fig.) ; these scales have concentric impressions on their 

 posterior extremities, and are 0-25 long, with their gi-eatest diameter 0'04. Eyes large ; the 

 orbits 0"7 in diameter, and rather more than their diameters distant from the point of the 

 jaw. Nostrils double, adjacent ; the posterior largest, with a valvular membrane on its ante- 

 rior margin ; a similar meml)rane on the hinder part of the anterior nostril. Jaws nearly 

 equal, with numerous acute minute recurved teeth in broad patches ; the external row largest.
