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 no 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 toBuJMENBAcn'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, Penlacrinus 

 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.

 the iWUSCf)elfl0rtjftalitStem, our lias, in the environs of Waltershousen. The 

 Baron observes that the fossil resembles the recent species, and that he possesses 

 columnar fragments in flint, which I suspect is the variety mentioned by me

3. PENTACRINITES EXCAVATUS. From the (QtfbergangfcalUgtrfn, (tran- 

 sition limestone) in the neighbourhood of Prag. The Baron possesses only 

 some roots from which many columns (l|)auptai'in Main Arms) proceed; and

T. 3. p. 336. t. 4. fig. 2. It is distinguished from all other species of Encrinites 

 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
