ZOOLOGY. — The correlation of phylogenetic specialization and 

 bathymetrical distribution among the recent crinoids.^ Austin 

 H. Clark, National Museum. 



In the recent crinoids there are thirty-seven pairs of obvious 

 contrasted characters which are commonly employed in distin- 

 guishing the various genera and families, and which are simi- 

 larly used in their fossil representatives. 



The two contrasted characters in each pair always differ in 

 that one represents a higher grade of phylogenetic specialization
