DONAX. 61 
onax striata. 
The Donax striata of Hanley’s ‘ Recent Shells’ (Knorr, 
Délices, pt. 6, pl. 7, f. 7), is marked for this species in the 
Linnean cabinet, and agrees correctly with its description in 
the ‘Systema.’ Our author, in his proposed thirteenth edition, 
has wisely changed “vulva” to “rima,” and, in his directions 
to the printer, written “locatur post 103” (that is to say, before 
rugosa, to which it is nearer allied than to trunculus). 
Honax Dewticulata. 
The Donax denticulata of authors is still present in its 
marked receptacle in the Linnean cabinet. The typical speci- 
mens (Donov. Brit. Shells, vol. i. pl. 24) correspond accurately 
with the characteristics ascribed to the species, of which 
examples (probably from ballast) are often picked up on the 
shores of the Mediterranean; but the mollusk itself is West 
Indian. 
Mowaxr cuneata, 
Linneus has only indicated his possession of this species in 
the list which accompanies his tenth edition; there are, how- 
ever, specimens (Born, Testacea, vignette p. 52) of the Donax 
cuneata of authors in the collection, which accurately correspond 
with the fuller description in the ‘Museum Ulrice.’ In that 
work, however, another species appears to have been mixed up 
with it (perhaps the D. faba, Chemn. Conch. Cab. vol. vi. 
pl. 26, f. 266, 267, of which there are also examples in the 
collection), judging, at least, from the expression ‘“ antice— 
glabra aut scabra,” the sculpture of the shorter extremity 
being a character of extreme importance in the genus Donaz. 
The “ parva,” too, of the ‘Systema’ is not exactly suitable to 
cuneata in relation to other Donaces. Nevertheless, unless the 
type in the Dronningen Museum, which even before the publi-
