456 SPECIES OF THE MANTISSA. 
immature specimen of the Rostellaria fusus, which was very 
fairly represented in the cited drawing of Argenville. 
-Buccinum rucosum.: The Cassidaria Tyrrhena of Lamarck’s 
‘Animaux’ (Chemn. Conch. Cab. x. f. 1461, 2) is thus named 
in the Linnean collection, which confirms the conclusion 
arrived at by both Dillwyn and Deshayes. 
BuccinuM MONILE, GEMICUM and pRoxmmatTuM followed hec- 
ticum in the copy of the ‘Systema’ that belonged to the 
younger Linné. It is probable that they were either Bullie 
or Terebre, but no salient characteristics have been men- 
tioned by which we can recognise the objects intended. 
Menke, in his ‘Synopsis,’ has indicated a Terebra as the 
~ Buccinum monile of Linneus; he has not, however, described 
it. 
BuccinuM crneuLatum has been asserted, by Hebling, Dill- 
wyn and Deshayes, to be the shell subsequently called Purpura 
trochlea in the ‘Animaux sans Vertébres.’ Examples of that 
whelk (Enc. Meth. Vers, pl. 422, f. 4) are still preserved in the 
box marked for the species in the Linnean cabinet. 
Murex succinetus. The Triton clandestinus (Chemn. Conch. 
Cab. xi. f. 1856,,7) is marked for this species in the Linnean 
collection. 
MvreEx conTrarius we learn, from the typical examples, to 
have been the Fusus perversus of Kiener’s ‘ Coquilles Vivantes’ 
(Fus. pl. 20, f. 1). 
NeERITA LACTARIA has been confidently pronounced, by both 
Dillwyn and Récluz, to be a mere white variety of the Nerita 
plicata of authors. 
PATELLA NOACHINA and miniraris followed antiquata in the 
copy of the ‘Systema’ that belonged to the younger Linné. 
The former is now generally recognised as our British Punctu- 
rella, the latter has been conjectured by Deshayes to be the 
Hipponyx subrufus.
