0:V THE SPBC'IES OF AfSiTKOSClOPUS OF 



STATES. 



THE EASTERN UNITED 



By TARL£TON II. BEAJV. 



The family Uranoscopidw of Gill lias two representatives on the east 

 coast of the United States, Astroscopus y-grcecum (C. & V.) Gill, and A. 

 nnoplus (C. & V.) Brevoort. The former was described from the Carib- 

 bean Sea, and is now for the first time recorded in onr waters. A. ano- 

 l)lus was founded upon young individuals sent by Professor LeConte, 

 and the immaturity of the specimens has led to considerable confusion 

 in the diagnoses of genera. Cuvier and Valenciennes su|)posed the spe- 

 cies to be scaleless. Drs. Gill and Giinther both em])l()yed tliis as one 

 of the characters separating it from Uranomopus^ the lattei- in 18(>0* 

 assigning the TJ. anoplos of Cuvier and Valenciennes to his new genus,
