In a note on p. 52, Mr. J. W. Salter suggests the new generic name of 

 Plutonia, but leaves the description for another article. 



A species of this genus was afterwards described and figured in the 

 same journal, vol. 27, 1871, pi. 15, figs. 1-8, under the name of Plutonia 

 sedgwicki Hicks. This large species has affinities with the genera Para- 

 doxides and Anopolenus in the form of its glabella, but differs, according to 

 Hicks, "in having the whole surface covered with coarse tubercles or 

 spines." The term Plutonia is objectionable, inasmuch as it was used in 

 1864 for a genus of the Mollusca.
