3121. OGCOCEPHALTJS RADIATUS (Mitchill). 



(SHORT-NOSED BAT-FlSH.) 



Head 2. Dorsal 4 ; A. 4. Rostral cavity somewhat broader than high, 

 or width equal to height; distance between anterior angles of orbits 

 about equal to that between the posterior angles; eye a little wider than 

 interorbital width : snout, exclusive of rostral tubercle, not produced 

 beyond the rostral cavity, but with a cylindrical button-like tubercle, 

 slightly contracted at base, pointing obliquely upward and forward, its 

 length 25 times in body ; posterior edge of pectoral slightly nearer base of 

 caudal than upper jaw; caudal peduncle very thick and heavy; vent 

 about midway between tip of jaw and base of caudal fin. Color brownish, 

 with dark round spots sometimes edged with white ; pectorals with a net- 

 work of white lines dividing the dark color into dark brown spots ; tip 

 of caudal blackish, belly coppery red. Length 8 to 12 inches. Coast of 

 Florida and neighboring waters; very common in shallow bays among 

 weeds, especially about the Florida Keys. Here described from a speci- 

 men from Cedar Key, Florida, 7 to 8 inches in length, (radiatus, rayed.)

Bahamas. 

 Malthe ciibifrons, RICHARDSON, Fauna Bor.-Amer., in, 103, 1836, said to be from Labrador 



(Coll. J. J. Audubon), but this is certainly an error; Audubon collected also in 



Carolina and Florida; GUNTHER, Cat., in, 203, 1861 ; JORDAN & GILBERT, Synopsis, 850, 



1883; JORDAN, Cat. Fishes, 139, 1885. 

 ? Malthcea truncata, CUVIER & VALENCIENNES, Hist. Nat. Poiss., xn, 454, 1837, America ; 



snout wholly obsolete ; perhaps a species of Zalieutes. 

 Malthcea angusta, CUVIER & VALENCIENNES, Hist. Nat. Poiss., xn, 454, 1837, Dutch Guiana; 



snout more than 20 in length. , 



1073. ZALIEUTES, Jordan & Evermann. 



Zalieutes, JORDAN & EVERMANN, Check-List Fish. K. and M. A., 511, 1896 (elater). 



Disk wider than long, about as long as rest of body (including caudal 

 fin); middle line of head elevated, but the forehead not projecting beyond 

 mouth ; rostral tentacle present, the cavity about as wide as high ; mouth 

 small; minute teeth on vomer and palatines. Gills 2|. Eastern Pacific. 

 The genus is very close to Malthopsis, Alcock,* but the latter, like Ogco- 

 cephalus, has the disk longer than broad, but the gills are reduced to 2.

Body very broad and depressed, the disk considerably broader than 

 long, its width 1 times in length of body ; back and snout considerably 

 raised above rest of body; greatest depth of body scarcely more than 

 width of mouth. Mouth small, its width greater than diameter of 

 orbit; snout very short, scarcely projecting beyond mouth, its length
