320 SPECIES OF THE SYSTEMA. 
naturalists to recognise it (Chemn. Conch. Cab. vol. v. pl. 173, 
f.1700, 1701), despite of its very faulty synonymy. The in- 
correctness of the latter (in which Rumphius alone can, per- 
chance, be retained) was eventually detected by our author, 
who, in his own copy, has queried the reference to Gualtier, 
appended “mala” to that of Bonanni, and written “male” 
after Argenyille; the want of an accessible accurate delineation 
forced him to quote such as might approximately remind one 
of its peculiar features. 
Our author bestowed his own specimen upon the Royal 
Museum, as he has with pride recorded, and does not appear to 
have possessed a second example. 
Trochus vesttaris. 
As in the references, so in the collection, two Rotella, the 
lineolata (Crouch, Introd. Lam. Conch. pl. 16, f. 14) and the 
monilifera (Sow. Genera Shells, Rot. f. 1) of Lamarck, were 
included under this appellation. If the name should be pre- 
served at all, it is preferable to bestow it upon the former, since 
the stated colourimg is more in harmony with its painting, and 
the remarkable sculpture of the latter is not mentioned in the 
description. 
Grochus labio. 
Two, or more, very distinct Monodonte (in the Lamarckian 
sense), have, at various periods, received this appellation from 
Linneus. For the “striato-tuberculata; apertura dentata” of 
the original diagnosis was changed in the twelfth edition of the 
‘Systema’ to “substriata, columella unidentata,” which accounts 
for the anomaly in the Linnean collection, that whilst the 
M. labio of authors (Born, Test. Mus. Vind. pl. 12, f. 7, 8) was 
descried in the marked receptacle of the species, a loose ex- 
ample of M. fragaroides was found inscribed with the indicative 
numerals. I consider the latter, to which alone the term “ sub- 
striata” can be applied, and to which the synonym of Gualtier 
belongs, to be the shell intended in the final edition, but the
