Area trapezia [= A. tuberculosa]. 
Sawicava leyunen [ =8. pholadis ; ?from hole of Lithophagus|. 
Petricola arcuata {=the normal state of P. carditoides, Cony. }. ‘ 
Petricola cylindracea [=a short form of the same sp., developing ridges of growth, 
like Tapes ruderata, Desh. |]. 
Venerupis gigantea [ = Saxidomus squalidus, Desh. ]. ¥ 
Cypricardia Duperreyt [= C. Guinaiaca, Lam.,=C. Californica, Cont. A Sandwich 
Island species, twice quoted, but not confirmed, from Cal. ]. 
Cardium Laperoussti [is an Aphrodite, like Greenlandicum, but more transyerse, and 
with lateral teeth less developed. ‘This very rare and probably boreal shell has 
just been identified from Adm. Sir E. Belcher’s coll. ]. 
Cardium Californiense, Desh. [is not C. Californianum (= Nuttalli’), Cony. ; but= C. 
pseudofossile, Rve., 1844. The name of Desh. is unfortunate, as his shell is the 
Kamtschatkan form with strong ribs. The Californian form is smaller, with 
fainter ribs, = C. blandum, Gld. }. 
Purpura Freycinetii [is figured from a very extreme form of the Japanese species. 
P. ostrina passes into similar’ varieties |. 
Velutina Miilleri (probably = V. levigata, which reaches Vancouver}. 
Lucina cristata [= Tellidora houdata, Holmes; described from the Pleistocene of 8. 
Carolina, and lately dredged alive by Dr. Stimpson; not 7. Burnett]. 
The following may be added to Deshayes’ list :-— 
Pl. 81. Tellina ligamentina, Desh., 1843, Hab. ?— [ = Macoma secta, Cony. ] 
Tellina Japonica, Desh., in Mus. Cum. [also appears to be M. secta, jun. ].

ing West Coast species and synonyms, in addition to those quoted in Rep. 
pp. 203-204 :—
