Syn. Compsocrinus S. A. Miller, 1883, Journ. Cincin. Soc. Nat. Hist., 

 vol. vi, p. 234. 



Compsocrinus was described by Miller from a species which 

 was said to possess a quadripartite base, supporting five radials 

 and an anal plate ; column quadrangular. Good specimens of 

 " Compsocrinus 11 Harrisi, Miller's type, from the collection of 

 Mr. Harris, who has the type specimens, show the number of 

 basals to be four, as described by Miller; but the interradials at 

 all sides rest upon the first radials, the posterior one not abutting 

 against the basals as was asserted, and this makes Compsocrinus 

 identical in structure with Mariacrinus as emended by us. If 

 Miller's diagnosis had been correct, Compsocrinus would have 

 been undoubtedly a good genus. Whether the column in other 

 species of Mariacrinus is quadrangular, is not known.
