the name Orthisina Missouriensis by Swallow, and it is probably identical with 
O. occidentalis of the same author. Dr. Newberry has described* the species 
Streptorhynchus pyramidalis, and S. occidentalis; the former of these may be iden¬ 
tical with Meekella striatocostata, though the original specimen appears to be of 
very large size and of rather more pronounced plication. Figures of the 
original specimens of the latter species are given on Plate XI c, showing it to 
be very distinct from M. striatocostata, and the largest known representative 
of the genus. In 1845 de Verneuil described from the middle and lower 
Carboniferous limestone of Russia, Orthis eximia;\ and 0. Olivierana, both 
of which unquestionably belong to Meekella, the former being of the type 
of M. striatocostata, the latter an evenly striated shell without the radiating 
costae, a type of surface ornamentation otherwise unrepresented in this group. 
Still another species has been described by Bayan,| M. Garnieri, from some 
fossils collected in the valley of the Yangtsee-Kiang, China, by the late M. 
Francis Garnier.

cotti of Eischer de Waldheim.
