§ The Genus AUoprosallocrinus, proposed by Casseday & Lyon, is prob- 

 ably identical with Conocrinus of Troost. Their description of A. conicus 

 corresponds in almost every particular with the characters exhibited by 

 specimens in my cabinet labelled Conocrinus tuberculosus by Troost. These 

 specimens are also from the same geological horizon as that described by 

 Casseday. I have always regarded Conocrinus as a subgenus of Actino- 

 crinus, and of doubtful value. 



|| As no description of Conwrinus tuberculosus was published by Dr. 

 Troost, Casseday & Lyon's name (proposed ten years later) must be adopt- 

 ed for the species.
