which I shall demonstrate when speaking of the genus Pentacrinites. A fine 

 specimen in my possession, showing the double serrated edge of the tentacula, 

 proves this assertion, since it exhibits a similarly formed margin to that which 

 marks the adhesion of the plated integument in PentacrinusCaput Medusae. 



Mr. PARKINSON calculates the number of joints forming Ihe superior por- 

 tion of this animal at 26,680, which would increase most surprisingly, were we 

 to take into account the minute calcareous plates, that are interwoven in the in- 

 tegument covering the abdominal cavity and inner surfaces of the fingers and 

 tentacula, and add them to the former. 



As an instance how often a superficial examination may lead men of ability 

 into error, MEINECKEN in JlMlltftyScher >ttiecfc, 8. p. 245. advances that the 

 tentacula so regularly arranged in the interior of the lily encrinite, have some 

 affinity to the septa in the orthoceratite, yet that these are formed of many 

 pieces ! 



The peculiarly fine lily encrinite figured by KNORK, tab. 11. a. was, it is 

 said, purchased (Jf3atUtfijrSdl)t H>tU0Cfc 3.) from the labourers at the limestone 

 quarry at Schrapland, near Halle, by Inspector WILKENS, for32groschin, and 

 given to Professor LANCE, who sold it to Baron NIEGART. However in the 

 same publication (s>tUWft 6.) it is stated that it was not bought by WILKENS, but 

 by Mr. VITIGO, at Farrenstadt, near Querfurt, for two dollars, and given to 

 LANGE, who sold it for three louis d'or. If my memory does not misgive me, 

 I think I saw the specimen about twenty years ago in the collection of the 



, at Pantzic. Where is it now?
