- 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 : 
. e 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. 
1, PENTACRINITES VULGARIS. Is our P. caput MEDUSE. The Baron gives 
the following additional synonymes and reference. VORTICELLA PENTAGONA 
Erris and Esper Vorr. t. 8. fig. 1. Guerraro Nux. vol. rr. Palma

t. 70. (308587 Zoologie, p. 108. He mentions but one new locality, which is 
. the Huscheliigetzkalkstein, 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

2. PENTACRINITES Brirranicus. Our P. Brıareus. The Baron gives the 
following additional synonymes and reference. VorticELLA PENTAGONA 
Davine. Esp. Perrir, t.6 A. Brumensacn’s Abbildungen 7,7 
Gegenstaende, 70. 1. a. und. b. 
3. PENTACRINITES EXCAVATUS. From the Uebergangkalkstein, (tran- 
sition limestone) in the neighbourhood of Prag. The Baron possesses only 
some roots from which many columns (bauptarne Main Arms) proceed; and 
quotes ScuroErer’s Einleftungen zur Maturgeschichte ver JDetrefactenkunde, 
T. 3. p. 336. ር 4. 85.2. Itis 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
