30 SPECIES OF THE SYSTEMA. 
being sufficiently characteristic: it is apparently the same en- 
sraving as that in his ‘ Historia,’ which is thus cited, “ List. 
t. 411,” in the manuscript of our author. Argenville probably 
intended to delineate the large Southern form: his engraving 
is very bad, but intelligible. 
Solen legume. 
Solen (Ceratisolen) legumen of authors (Wood, Gen. Conch. 
pl. 28, f. 4, 5) has long been recognised for this species, thanks 
to the figures in Gualtier and Plancus, and the correctness of 
the recorded locality. The reference to Adanson (only added 
in the twelfth edition) is an error. 
In the revised copy of the ‘Systema,’ where our author has 
written ‘“‘ Costa rudimentaris in medio teste, nec ad anum 
propinq(ua) ut in 88 (radiatus),” the additional synonym of 
“ List. t. 420” supports the received opinion. 
Solew cultelus. 
Linneus did not possess this species, which, through the 
excellent description in the ‘Museum Ulrice’ and the quoted 
figures, has been satisfactorily identified as the Solen cultellus 
of authors (Crouch, Introd. Conch. pl. 2, f. 14). 
Solew radtatus. 
Many individuals of this pretty shell (Solen radiatus, Wood, 
Gen. Conch. pl. 31, f. 1, 2) are still preserved in the Linnean 
cabinet, and alone of those present exhibit the required charac- 
teristics of the species. “ List. t. 422” and “nymphe in- 
truse ” are added in the manuscript.
