 Tkipi.esia, or Triplasia as it should be 

 spelled, can not be changed into Trip- 

 lecia as suggested bv Hall in 1892, Pal. 

 N. Y., vol. 8, p. 269. In that event 

 Dicraniscus would have priority. But 

 Triplasius among the insects does not 

 interfere with Triplasia among the fos- 

 sil brachiopods.

Coleoloides, Walcott, 1889, Proc U. S. Nat. 

 Mus., vol. 12, p 37. [Ety. Coleolus, a 

 genus; oides, like.] , Shell slender, 

 elongate, cylindrical, straight or slightly 

 curved, apparently thin ; surface marked 

 by very fine, slightly oblique, longitudi- 

 nal striae. Type C. typicalis, described 

 at the same place from the Up. Taconic. 

 A poor definition without illustra- 

 tion. 



Conularia, above the septum, is often 

 broken off, and it has been suggested 

 that it may have fallen off during the 

 life of the animal; hence the shell is 

 sometimes called deciduous, from decide, 

 I fall off. 

 gracilis, Herrick, 1888, Bull. Denison 

 Univ., vol. 4, p. 48, pi. 8, fig. 2 ; vol. 3, 

 pi. 6, fig. 13, Waverly Gr. The name 

 was preocupied by Hall in 1847. As 

 the species appears to be distinct from 



all others, I now propose the specific 



name herricki. The species will then 



be called C. herricki, after Prof. C. L. 



Herrick.
