TAPES. 355 



so long gone by that name, that it would be unadvisable 

 to change it. It is probably his V. lata. Dale called 

 it Pectunculus fasciatus ; and this name has the pre- 

 cedence of all others. I will adduce a few out of the 

 numerous synonyms published by different authors : 

 V. edulis, Chemnitz ; V. rhomboides, Pennant ; V. Beu- 

 dantii, Payraudeau; and V. virago, Loven. In its 

 younger state it appears to be the V. nit ens of Scacchi, 

 but not of Turton.

BODY thick, oblong, greyish, yellowish, or very pale bluish- 

 white, sometimes tinted with pink : mantle having wavy or 

 jagged edges, which project a little beyond the valves ; the 

 indentations or folds are stronger at the sides than in front ; 

 within the margin are a few scattered white tentacular papillae : 

 tubes nearly equal in length and diameter, the upper being a 

 trifle longer than the lower, but not quite so large and more 

 conical and contracted at the opening ; they vary in length 

 from being only one-half to quite as long as the shell is broad ; 

 the upper serves for excretal and the lower for alimentary 

 purposes ; both are cylindrical or funnel-shaped, and joined 

 together until about one-fourth of the distance from the orifices, 

 where they diverge, the upper curved backwards and the lower 

 forwards ; they are closely wrinkled across, and the upper or 

 outer third portion is irregularly traversed with brown streaks 

 or lines; the orifice of each tube is tinged with brown of 

 various shades, red, orange, or flake -white, and fringed with 

 short finely ciliated filaments, those of the upper tube being 

 plain, and the other set arranged in a double row ; the inner 

 row consists usually of a few only, which are erect and longer 

 than the outer row, and branched or studded at their sides 

 with short points, like the gills of some Nudibranchs ; the 

 outer row is twice as numerous, very much shorter, and folded 

 outwards; the edge of the lower orifice is considerably ex- 

 panded, like a bell, when the animal is feeding : gills pale
