OIV THE SPECIES OF ASTKOSCOPr.S OF THE EASTERN UMTEH 



STATES. 



By TAKI.ETON IS. BEAN. 



The family TJranoscopidiv of Gill has two representatives on the east 

 coast of the United States, Astroscopus y-(jrwctim (0. & V.) Gill, and A. 

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

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

 plus was founded npon 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 supposed the spe- 

 cies to be scaleless. Brs. Gill and Giinther both employed this as one 

 of the characters separating it from Uranoscoims, the latter in 18G0* 

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