TELEIOCRINUS W. X Sp., Rev. ii, p. 146. 



In the second part of the Catalogue of Amer. Pal. Foss., p. 

 268, Miller calls Teleiocrinus " a subgenus of doubtful utility." 

 The fact is we proposed it as a full genus of the Actinocrinites 

 and not a subgenus of Strotoerinus. We stated expressly, Tel- 

 eiocrinus holds the same relation to Actinocrinus as Strotoerinus 

 to Physetocrinus, which, curiously enough, are both accepted by 

 Miller. Probably all these genera are descendants of Actinocrinus, 

 and it is difficult to see how Miller can reject Teleiocrinus when 

 he accepts Strotoerinus.

 described from New Mexico, came from the Lower Burlington limestone, 

 and not from the Keokuk group. — Lake Valley, New Mexico.

*1859. B. grandis (Lyon), Actinocrinus grandis, Amer. Journ. Sci., vol xxviii 

 (September), p. 240. — Keokuk limest. Kentucky and Tennessee. — In the 

 original description of this species, by mistake of the printer, the specific 

 name was omitted. Lyon evidently intended to name the species Act. 

 grandis, as that name is mentioned at the end of the description in dis- 

 cussing the geological position. We adopt this specific name, but place the 

 species under Batocrinus. It has two arms extended from each arm base, 

 a character only found among the Batocrinites.
