An Encrinite with twenty rays is mentioned by M. Schulz; 

 but M. Walch, although unwilling to doubt the fidelity of 

 the description given by M. Schulz, remarks, that it is pos- 

 sible that the arms of the common encrinus, or stone-lily, 

 might have been reckoned after their division, and thus the 

 real number might have been doubled. The probability of 

 this will be allowed, when it is considered that the imper- 

 fect state of a specimen often occasions very deceptive ap- 

 pearances ; and this probability will be still more readily 

 admitted, on considering the formation of the cap encrinite, 

 Plate XV. Fig. 9? in which, from the irregularity and 

 the greater frequency of the subdivision of its limbs, the 

 animal might be supposed, by an inspection of its supe- 

 rior part only, to have possessed double the number of 

 arms which it really does. 



The appearances presented by the polished slab of marble, 

 containing the pentacrinite of M. Gmelin, hardly at all 

 differ from those which present themselves in the pentacri- 

 nital marble of Dorsetshire. 



Of the supposed pentacrinite, discovered by M. d'Annone in 

 a piece of the calcareous stone of Pappenheim, little posi- 

 tive can be said. Since only the terminating branches and 

 no part of the trunk of this animal was discovered, it is 

 impossible to determine whether it should be considered as 

 an encrinite, pentacrinite, or fossil stella marina ; but from 

 the very close resemblance which it bears to the Stella 

 $sKctKVYipo$ barbata sen Jimbriata Barrellieri, figured by Linck, 

 Tab. XXXVII. Fig. 64, as well as to 'others of the Stella 

 Crinitce, there appears to be very strong reason for suppos- 

 ing this fossil to be the remains of some of these species of 

 Stellae.
