So named because the head is ornamented with iain which 
so nearly resemble the antennz of recent crustaceans, that this genus 
which we have ventured to propose, seems to form the link that was 
* Pror. Seas Dae Sir—I am desirous to make use of your valuable 
Journal to publish an account of a new sone which has been recently discov- 
ered. It differs so oe, from the genera that we Fag cade ribed, and is yet so 
pie a member of the race, that the sacl of a

sion eh is apt to grow out of needless distinctions, and too great subdivisions of 
natural families. Although it is generally admitted that they are evidently analo- 
gous to the crab, it has been often and strenously denied that trilobites possessed any 
— NS ONS to their antenne. We are now prepared to offer conclusive 
ony to the contrary. The specimen, of which we send you a drawing, was 
found at Springfield, Clark county, Ohio, in the same locality with the Colymete 
Blumenbachii, bufo? phlyctanoides, and other rare fossils—(all the remains found 
in that rock are casts of the inner or under side of the crustaceous ch, 
the one under consideration I procured last week from the cabinet of Mary A 
Warder.
