Habitat. — South Atlantic coast of the United States from Long

Etymology. Anoplos, unarmed. 



This species seems to be rather rare on our coast, but few speci- 

 mens having been taken, and these of small size, 2 to 5 inches long.

 Dr. Jordan at Key West.

Type. Uranoscopus Y-graecum Cuv. and Val. 



Etymology, y, psilon ; phoros, Y -bearing. 



This genus is well distinguished from Astroscopus by the peculiar 

 armature of the top of the head. Two species are known, both of 

 the New World. 



Naked space between forks of the Y on top of head long and 

 narrow, shorter than the vertical limb of the Y ; no distinct spines 

 before eye; white spots on body distinct, each surrounded by a dark 

 ring; eye 3-3 j in interorbital space ; base of the two dorsals greater 

 in length than distance from front of first dorsal to tip of snout ; base 

 of first dorsal twice length of its first spine; first spine equals in 

 length the third, and half that of the second, and slightly exceeds 

 the fourth ; base of second dorsal equals twice length of its longest 

 ray ; caudal equal in length to ventrals ; pectorals longer than 

 ventrals and extending to middle of second dorsal. Color dark 

 brown above, white below ; upper parts covered with small roundish 

 white spots, each surrounded by a dark ring ; lower jaw and labial 

 fringes similarly spotted; spinous dorsal black, white posteriorly;
