106 Description of a New Fossil. 



Art. XII. — Description of a Neio Fossil, (Calymene Buck- 

 landii;) by John G. Anthony.* 



Cincinnati, February 5th, 1839. 



TO PROF. SILLIMAN. 



Dear Sir. — Having within the past month discovered near this 

 place, another undescribed fossil, I herewith forward a description 

 to you, with a request that it may appear in the columns of your 

 Journal. 



Calymene Bucklandii. Anthony. 

 Cabinet of John G. Anthony. 



Clypeo antice rotundato, sub-convexo, granulato et punctate ; 

 oculis minimis, remotis in lateribus capitis ; tuberculis sex, dis- 

 tinctis, in lateribus frontis. 



The buckler of this species is semilunate ; the front sub-trian- 

 gular, and covered with granulations; the margin of the front is 

 thickened and rounded, that of the cheeks flattened out ; its pos- 

 terior raised rim running nearly parallel with the articulations of 

 the abdomen. The front has three nearly equal tubercules on 

 each side, placed in a deep furrow which separates it from the 

 cheeks ; the eyes are very remote from each other, being situated 

 near the lateral angles of the cheeks. The cheeks form spherical 

 triangles covered with minute granulations, having small de- 

 pressed points among them. A narrow raised line passes from 

 the angle formed by the lip and margin, and is attached to the 

 oculiferous prominences, and a depressed line has an attachment 

 near it at the under part of each eye and passes over the anterior 

 margin. 



The tail and part of the abdomen are wanting in this, the only 

 specimen yet discovered; eight articulations only remain. These 

 articulations possess a peculiar character, one which I have never 

 observed in any other species of Calymene ; the costal arches of 

 the middle lobe although in reality separated from those of the 

 lateral lobes by a deep furrow, have the appearance of passing 

 beyond this furrow, and becoming interwoven with them. The 

 lateral arches are nodulous.
