an account of the encrinital remains in his collection, applying names to those 
varieties which appeared to him entitled to specific distinction. And although 
he furnishes ne anatomical details, yet his localities and synonymes are suf- 
ficiently valuable to induce me to present the following extract from his work : 
He places the family, according to BLuMENBACH’s arrangement in the order 
of Crustacea, {meaning by that term those radiated animals which have crus- 
taceous plates, an application which cannot be admitted in our system, where 
it has been appropriated to the crab tribe) forming of it two genera, Pentacrinus 
and Encrinus. He observes in a note, that they do not belong to the 
Zoophytes with which Lamarck has arranged them, but rather form a link 
between the Crustacea and Zoophytes. In this I fully agree with him.

3. PentTacrinites EXCAVATUS. From the Gebergangkalkstetn, (tran- 
sition limestone) in the neighbourhood of Prag. The Baron possesses only 
some roots from which many columns (ibauptarme Main Arms) proceed; and

by its plate-like concave joints, ornamented externally with a fine projecting 
rim. The Baron further says that, according to verbal information, its upper 
columnar joints articulate alternately with pentagonal ones, displaying star-like 
markings. Yet he suspects that it is not a Pentacrinite, but Encrinite ; I
