In the Monograph of the Miocene of Astoria and Coos Bay, Oregon, I have 
fully explained my reasons for regarding Odcorys as a member of the 
family Cassididae, rather than, as Fischer thought, entitled to a separate family of 
its own. 
In the Blake Report (1889, p. 228) I divided the genus from Atlantic speci- 
mens into two sections as follows: 
Section Odcorys s. s. Type, O. sulcata Fischer. 
Shell not umbilicate, pillar twisted, obliquely truncate, without a marked siphonal 
fasciole, outer lip smooth. 
Section Benthodolium V. and 8. Type, B. abyssorum V. and 8. 
Shell with a narrow but distinct umbilicus and a strong siphonal fasciole ; 
outer lip obscurely denticulate when fully adult. 
Since then, having seen more material, I am in doubt whether these sections 
should be maintained or not, though complete continuity between them is not yet 
established. The range of variation is hardly known. It will be observed that 
I agree entirely with Locard in his “ Talisman ”’ report as to the relations of the 
genus to the Cassididae and, I may add, in referring to it Watson’s Buccinum 
aguilarum from near the Azores. The species now known are O. aquilarum 
Watson, O. sulcata Fischer, 0. abyssorum V. and 8., O. watsoni and O. fischeri 
Locard, from the Atlantic, and the following forms from the Pacific.
