 Dealing exclusively with the 

 families Salenidse, Arbaciadffi, 

 Aspidodiadematidie, and Dlade- 

 matidse, this paper gives a general 

 review of the genera and species 

 in each of these families, especially 

 in reference to the pedicellarise. 

 which structures are described in 

 great detail, with numerous fig- 

 ures. Hawaiian species are treat- 

 ed at length and figured. A new 

 genus, Eremopyga, is erected for 

 Astroptjfja dcnudata de Meijere.

chased by Mr. Frank Springer and.

The genus Ptilocrinus.

 541-543. 

 A review of a paper by Dr. F. A. 

 Bather of the British Museum de- 

 scribing a second species of Ptilo- 

 crinus from the antarctic regions. 

 The distribution of the recent cri- 

 noids is discussed, w'hereby it is 

 shown that the entire western 

 coast of America from the ant- 

 arctic regions to Bering Straits is 

 purely antarctic in so far as the 

 crinoids are concerned, and, there- 

 fore, that the discovery of a sec- 

 ond species in the antarctic of a 

 genus originally known from 

 British Columbia was only to have 

 been expected. 



The Nomenclature of the Re- 

 cent Crinoids. 



Proc. U. 8. Nat. Mus., 

 XXXIV, No. 162.3, Aug. 25, 

 1908, pp. 435-542. 

 A list of all the generic and 

 specific names which have ever 

 been applied to recent crinoids is 

 given, with the correct first refer- 

 ence, type locality, and present 

 location of types of species, and 

 types of genera, together with the 

 derivation of the names. Two 

 new names are suggested to re- 

 place preoccupied names.
