APPENDIX. 



Classification of the Crinoidea (p. 445). 



Dt P. Herbert Carpenter has kindly supplied the author with 

 the following note as to the classification of the Crinoids proposed 

 by Neumayr in his recently published important work " Die Stamme 

 des Thierreichs " : "The new classification of the Crinoidea pro- 

 posed by Neumayr is primarily based upon the condition of the 

 mouth and ambulacra. These are either subtegminal (Hypasco- 

 crince) or free and exposed upon the ventral surface (Epascocrincz). 

 The first-named group includes all the Palaeocrinoids, except Cya- 

 thocrinus and its allies (Families 12-20), which have been already 

 distinguished as Fistulata by Wachsmuth and Springer. It has 

 also been shown by these authors that some of the Ichthyocrinidce, 

 at any rate, had an exposed mouth and open ambulacra (see p. 

 431); so that this family can find no place in the Hypascocrincz. 

 Except, too, for having a subtegminal mouth, the Haplocrinida and 

 their allies (Larviformia) seem to be more closely allied to the Fistu- 

 lata than to the other Palaeocrinoids (Camerata)" 



The general relations of Neumayr's classification to that proposed 

 by Wachsmuth and Springer may be seen in the following table : —

An important posthumous work by M. Joachim Barrande on the 

 Cystideans of Bohemia has recently been published, and Dr P. 

 Herbert Carpenter has been good enough to furnish the author
