Note. — In the Proceedings of the Academy of Natural Sciences, 

 Philadelphia, for December, 1865, just received, I observe (p. 273) 

 that Meek & Worthen change their name Sphccrocrinus, proposed 

 for a section of Actinocrinus, to that of Ccelocrinvs, the former name 

 having been previously used by Roemer for another group. As the 

 term Caliocrinus, however, was employed by White in 1863 to de- 

 signate a subgenus of Poteriocrinus, it will be necessary for Meek 

 & Worthen to give another name to their proposed subgenus. 



The publication of this Catalogue will be continued in the next 

 number of the Transactions of tbe Academy, which it is proposed 

 to commence without delay. This number will embrace the Bryo- 

 zoa and Brachiopoda. It is also expected that it will contain a 

 Catalogue of our Palaeozoic Plants, which Prof. Leo. Lesquereaux, 

 the eminent fossil botanist, has kindly consented to prepare in aid 

 of the work. 



t In this place Mr. Billings expresses the opinion that his Genus Pasce- 

 olus may be congeneric with Cyclocrinites, Eichwald, thougli he considers 

 the question yet unsettled as to whether its affinities are with the Ascidi- 

 arts or Cystideans. Messrs. Niles and Verrill, however, after a study of 

 some well preserved specimens of Pasceolus Halli from Anticosti, unhesi- 

 tatingly refer them to the Cystidea.
