V^alvi's, beath. 



Common on .lames Island where numerous, ]>vineipally rij^ht, valves 

 were obtained; three valves Hood Lsland. K'eeve says that "it is with 

 no little <;ratilieation that I now publish a ^'ood illnstratixe tigure of a 

 species described thirteen years since by M. Michclin from a worn odd 

 valve. The Cardita raria is the nearest allied species to it, but that 

 shell is of smaller dimensions, rounder and slightly noduled; the paint- 

 inj»' is also of a ditVerent character." 



After a careful comparison I feel warranted in nnitinu' tiie three species 

 as above under IMicheliirs name. I am quite familiar with these forms 

 and the color distinction is of no value. These shells vary considerably 

 in the other characters to which Keeve refers; but in the essential 

 features of outliiu', growth, zones, etc from adolescence to uniturity, 

 as well as in the number of ribs and the hinue characters, tlu'y are 

 identical.

'file lirst named from Chatham Island. Abundant on Hood Island; 

 two left antl one riuht vahc and one perfect fresh specimen Irom In- 

 defatigable Island. I am inclined to regard Carpenter's I.. jnrtiii<t(i( 

 Ma/., catalogue sj)., ML', as a varietal aspect of this species. The tihiila 

 ofWinnner's list is probably this species. Car])enter, in Brit. Assn.
