_ For want of. any systematic work. on ve fossils: ‘of.0 our strata, 
I cannot venture to say whether it is described or not. It is un- 
doubtedly one of the encrinite family, probably an apiocrinite, 
and the present drawing is forwarded for publication in your 
Journal, with a view to enable some one better nequalnias with 
the subject to determine its specific name. 
The letter accompanying the notice of Dr. Warden’s trilobite 
in your daly: number,* is calculated to convey an erroneous-impres- 
is. species is entitled to priority. ‘The statement made 
to me 5 by Dr. W. was, that his sister-received the specimen from 
some one, and had-put it away with many others, without being 
aware of its true character, and that. on his visit to Springfield 
out a month after he saw; my specimen, he. noticed this, and 
brought it away. with him to Cincinnati... That Dr. W, was not 
aware of its existence previously, is evident, for he drew up the 
report alluded to in his letter, and therein says, “it is undoubt- 
edly the shield of an undescribed trilobite furnished with feelers 
or tentacule ; this is a very important fact. to establish, as it will 
prove ebtitlusively; that the trilobite family are properly consid- 
ered analogous to the crabs,” é&c. &c.° Throughout the report he 
makes no allusion. to ‘any other specimen as bearing any analogy 
with it, or conflicting in any degree with its claim to priority. 
As this claim was set forth in my communication to the Acad- 
emy, and as he takes no notice of it in his report, it is evident, 
that at. the time, the-existence of his sisters specimen ve un-
