We are here furnished with another illustration, among many 
seen on every side around us, of unmistakable evidences of per- 
fected thought in their creation, each being peculiarly adapted to 
the position it holds in the divine economy. 
I am indebted to Dr. Ida A. Keller for the accompanying 
drawings and explanation of figures.

On the Carpels of Opulaster malyacea (Greene). 
This species was originally described by Prof. Greene in Pitt. 
2: 30, 1889, as Weillia malvacea, from specimens collected by the 
author himself at the north shore of Lake Pend d’Oreille, in 
Idaho. In the diagnosis of the species it is referred to a section 
of the genus characterized by indehiscent carpels.
