54. CO. B. Adams.—After arranging the duplicate Reigen Collection in the 
State Museum at Albany, New York, I procecded to Amherst, Mass., to 
study the type-collection from which Prof. Adams’s book was written. The 
result is embodied in a “ Review of Prof. C. B. Adams’s ‘ Catalogue of the 
Shells of Panama,’ from the Type Specimens,” written for the Zool. Soc. in 
Jan., and published in the Proceedings for July 1863, pp. 339-369. In this 
paper the synonymy between the Mazatlan and Panama Catalogues is pointed 
out, and the species assigned to the modern genera. The following are the 
principal corrections needed in the list, Rep. pp. 267-280. ‘The resultsi n 
the succeeding paragraphs, pp. 280, 281, should be altered accordingly.

specimens of ce@rulescens.

70. Purpura foveolata, probably =worn sp. of Cuma costata, M. 610. 
74, Purpura osculans+ Rh. Californicus+ Rh. distans, are probably vars. of Rhizo- 
cheilus nux. 
81. Columbella costellata, C. B. Ad.,= Anachis scalarina, Shy. 
98. Columbella parva, C. B. Ad.,=dead sp. of Anachis pygmea.
