(m) A genus established by M. Recluz in the Revue 
Cuverienne of last year. Although nearly allied to 
Kellia, it is evidently a natural genus, and is most easily 
recognised by the broad ligamental plate. The charac- 
ters are as follows :—‘* Ovate or roundish, transverse, 
equivalve inequilateral, closed. Two cardinal teeth in 
each valve, (but not as in Kellia on the same side of the 
umbo.) A ligamental pit running alongside of the single 
lateral tooth. Muscular impressions oval, equal. No 
palleal sinus. 
(n) I received from Mr. Bean of Scarborough some 
shells thus named. They are so minute as almost to 
baffle microscopic observation. I perceive, however, two 
approximate cardinal teeth on the same side of the umbo, 
and a very indistinct anterior lateral one. These charac- 
ters are those of Kellia proper. The ligament is very in- 
distinct. The shell is elliptical, smooth, glossy, very in- 
quilateral, pale olive with a purplish tinge at the beaks, 
pellucid,
