TROCHUS. 3819 
the words of the ‘ Systema’), but even the few features that are 
specified do not accord with the existing characteristics, for the 
oblique painting is not composed of pale bands, but dusky lines, 
and the whorls are not rounded, but almost planulate. The 
Linnean appellation can have no claim to precedence, on its 
own merits; to quote an inapplicable description is but to 
foster error. The shell has been termed lineatus (a suggestive 
epithet) by Da Costa, who has clearly defined it, and, since it 
was impossible for him to recognise the Linnean shell from its 
published definition, it seems but justice to retain his name 
for it. 
Trochus Dibavicatus, 
The Trochus diwaricatus of Philippi (Payraud. Coq. Corse, 
pl. 7, f. 3, 4 as Monod. Lesson) is preserved in the box thus 
marked in the Linnean cabinet, where it exclusively answers 
(thanks to the peculiarity of colouring) to the definition. The 
locality enabled Philippi to detect the species, despite of the 
insufficiency of the description and the absence of synonyms. 
Srochus wudiltcar(s. 
In the box marked for this shell in the Linnean cabinet is 
preserved the T’rochus fuscatus of Gmelin and Deshayes (Born, 
Test. Mus. Vind. pl. 12, f.1, 2), which admirably agrees with 
the description of it by Linneus. This confirms the recogni- 
tion of it by Born and Philippi, who must have arrived at their 
conclusion from faith in the assigned locality, since the short 
and unillustrated description would in all probability apply to 
more than one species of T'rochus. 
Grochus solaris. 
This graceful shell is one of the very few which first appeared 
in the ‘Museum Ulrice,’ where the copious details enabled
