CATILLOCRINUS,t Troost, 1850. List Crin. Tenn., Proc. Amer. 

 Assoc. Camb. Meet., p. 60. 



* It is quite probable that all the species of Caryocrinus mentioned in 

 Troost's list are merely varieties of C. ornatus, Say. 



t As no description of Troost's Catillocrinus has been ptiblished, I am 

 pleased to be able to add the following, drawn from a specimen kindly 

 communicated to me by Prof. Litton of this city, for that purpose. 



Genus Catillocrinus, Troost. 



Generic Character. — Basal pieces 5, small, forming together a low cone. 

 Primary radials 5? Secondary radials 5, very irregular in form, two of them 

 large, transverse, somewhat lozenge-shaped ; two subquadrangular, one 

 lanceolate ; their superior edges broad and marked with strong, radiating 

 curved sulci. Arms slender, numerous (facets for 56 in the specimens bo- 

 fore me), arising directly from the upper straight edges of the secondary 

 radials. Column large, round, the superior joint concealing the basals and 

 nearly the whole of the primary radials.
