Calymene meeki — retrorsa. 



(Plate in, tig. 19. J 



In the \\'aynesville bed. a form of Calymene meeki occurs 

 which differs chiefly in the narrower posterior width of the cepha- 

 lon, resulting- in more obtuse g'enal angles, inclined to be more or 

 less rounded toward the tip. The anterior border of the cephalon 

 is more strongly reflexed. Ijringing it closer to the anterior margin 

 of the glabella. The specimen figured was obtained in the Clarks- 

 ville division of the ^^'aynesville bed, east of Dunlapsville, Indiana, 

 half a mile above the mouth of Silver creek. It is doubtful whether 

 it will be possible to ditYerentiate the W'aynesville specimens from 

 those in the ]\Iaysville, but the present is at least an attempt. 



Calymene is rare in the upper part of the Richmond forma- 

 tion, from the Liberty to the Elkhorn. but occasional specimens 

 may be found. These usually are rather small. 



Dalmanites carleyi — rogersensis. 



A species of Dalmanites, very closely allied to Dalmanites 

 (Pterygometopus) carleyi, occurs in the lower part of the Eden 

 section beuween Rogers gap and Sadieville: about ten feet above 

 the railroad track at the first large exposure west of bridge 54, 

 west of Alillion tunnel, in Madison county; and at the cut east of 

 Hatton ; all in Kentucky. Compared with Dalmanites carleyi, from 

 the Fairmount bed at Cincinnati. Ohio, the Eden specimens differ 

 chiefly in their larg-er size, the cephalon attaining a width of 20 

 mm., while the cephalon of the Fairmount specimens usually do 

 not exceed 15 mm. That part of the glabella wdiich lies posterior 

 to the frontal lobe is more elongate and slightly less constricted at 

 the nuchal segment. The pygidium also is closely similar to that 

 of the Fairmount form. The chief interest in these Eden speci- 

 mens consists not in their distinctness from the Fairmount species, 

 but in their very close relationship, increasing the number of 

 species in the Rogers Gap fauna, which may be regarded as pre- 

 cursors of the Fairmount fauna. 



Pasceolus camdenensis, sp. nov. 



(Plate II, fig. 6.) 



In the American ]\Iuseum of Natural History, in New York 

 City, there is a specimen of Pasceolus which is labelled as coming
