 {aphrodite) gronlandiciim, var. album, V.— 
 I specimen from the Bank. The 
 valves of this handsome variety 
 are of a pale drab and semitrans- 
 parent, whilst those of the type 
 are variously and prettily mar- 
 bled. 
 
 21. Cardita borealis, conr. var. St. jfohnensis, Verkr.—

 lot corn- 
 distinct 
 a broad- 
 shape ; 
 
 it is not inflected at the lunule 
 below the umbones, and which 
 the latter do not project, as it is 
 more or less the case with the 
 typus ; it is finally much smaller, 
 the largest dead adult valves 
 being scarcely half the size of a 
 typical cardita borealis from 
 neighboring Southern seas. I 
 am inclined to consider it a good 
 species and would retain the 
 name : Cardita St. Johnensis, 
 Verkr. 
 
 Cardita borealis, var. — Narrows, rare. This var. 
 
 has the shape of the type 
 but not the wrinkles on 
 its strong radiating ribs, 
 but is smooth and of a 
 lighter colour. 
 
 Mysihis edidis, L. — Harbour, common. 
 
 Modiola modiolus, L. — Harbour and outer sea,

 not show the rectangular 
 ribs on the shields, which 
 are peculiar to the type, or 
 sometimes very faintly only, 
 but it is covered over with 
 minutt pustules, not visible 
 to the naked eye. 
 var. St. jfohnensis, Verkr.— This 
 elegant variety is of a brilliant 
 green color, especially when 
 alive, and in sculpture inclines 
 rather to the preceding variety 
 more than to the type, I obtain- 
 ed but few specimens.
