EASTMAN: FISHES FROM UPPER EOCENE OF MONTE BOLCA. 345 



new manuscript has satisfied the Editor that the proposed alterations do not 

 justify the expenditure of time and money which would be called for in practically 

 resetting the entire article. In deference, however, to the wishes of Mr. Eastman 

 the Editor incorporates the essence of certain of his pages which seem worthy of 

 being printed. 



After relating the result of several private interviews with Dr. Theodore N. 

 Gill, the Author announces that the so-called " Toxotes antiquus" (cf. pp. 337-8) 

 should definitely be regarded as belonging to the fossil Labroids, and suggests the 

 erection of a new genus for its reception, for which, in honor of Dr. Gill, he pro- 

 poses the generic name Gillidia. The Editor takes pleasure in printing the diagnosis 

 supplied by Dr. Eastman. W. J. Holland.] 



Gillidia, gen. nov. 

 An extinct genus allied to Eolabroides, known at present only by the type 

 species, which was described by Agassiz under the name of Toxotes antiquus. 

 Head relatively. long and low. Body of moderate size, compressed, fusiform, the 

 dorsal contour from the snout to the middle of the back scarcely arched. Dorsal 

 fin with six spinous rays, of which the first is short, and none are longer or stouter 

 than the succeeding twelve articulated rays. Anal fin much shorter than the 

 dorsal, with three stout spines followed by twelve branched rays. Caudal fin 

 expanded, scarcely cleft, the superior lobe with eight, and inferior with seven, 

 articulated rays. Squamation coarse, especially in the flank-region; scales with 

 posterior margin entire.
