NOTES. 197 



Altogether fifty-six species are figured, which with one exception were 

 known forms. The specimens were in Mr. Hanley's own collection, and 

 of these twenty are now in the British Museum, having been given by 

 Mr. Henry Harvey, the present possessor of the collection. 



The apparent scarcity and curious form of this work must be my apology 

 for these few remarks.

Paradione, N.N., VICE Chionella. {Read 8th January, 1909.) — 

 In my Synopsis of the Veneridee (Proc. U.S. Nat. Mus., 1902, vol. xxvi, 

 p. 351) I adopted the name Chionella, Cossmann, 1886, for a section 

 of Macrocallista, Meek, 1876. Ghionella, however, had been previously 

 used by Swainson (" Malacology," 1840, p. 335, note), and I will now 

 substitute for it the name Paradione, with the type Cytherea ovalina, 

 Deshayes.
