 Key to the genera. 



a. CoTTiN^. Spinous dorsal shorter than soft part, less than XIII spines. 



b. Gill-membranes broadly united to isthmus, not forming a fold across 



it; fresh-water forms with feebly armed head. uranidea 



bb. Gill-membranes free from isthmus or else forming a broad fold 



across it. myoxoce;phalus 



aa. Hemitripterin^. Spinous dorsal longer than soft part, of XIV to XVIII 



spines. hemitripterus 



Genus Uranidka DeKay. 



The Blobs. 



Uranidea gracilis viscosa (Haldeman). 

 Blob. vStar Gazer. 



Head 3; depth 4^ ; D. IX, 18; A. 12; width of head 1% in 

 its length; snout 3^^ ; eye 4; maxillary 2j4 ; interorbital space 7; 

 least depth of caudal peduncle 4^; pectoral i^/^; ventral 1%. 

 Body rather slender, fusiform, compressed. Head moderately 

 broad, convex above, and flattened below. Snout convex, 

 rounded. Eye ellipsoid, well anterior and superior. Mouth 

 moderately large, and jaws about even. Maxillary reaching mid- 

 dle of orbit. Teeth in jaws in broad bands, villiform. Vomerine 

 teeth villiform. Interorbital space level, a little depressed an- 

 teriorly. Preopercle spine broad. Opercle ending in concealed 

 spine. Gill-rakers a few short stumpy tubercles. Skin smooth. 

 Origin of spinous dorsal opposite that of pectoral. Origin of 

 rayed dorsal a little nearer base of caudal than tip of snout, and 

 its base twice that of spinous dorsal. Anal inserted a little pos- 

 terior and tips of radii free or edge of fin notched. Caudal 

 rounded. Pectoral large, reaching a little beyond anal, and radii 

 of lower half of fin graduated down forwards with their tips 

 free. Ventral inserted a trifle behind lowest pectoral ray, -A, of 

 space to anal. Color olivaceous, mottled, upper edge of spinous 

 dorsal pale. Length 3^ inches. *'Beesley's Point." 



The above-described example is the only New Jersey one I 

 have. The occurrence of the species near Beesley's Point is per-
