SERPULA. 439 
the shell designed by Linneus, and the hypothesis is in some 
measure supported by the presence of many individuals of it 
(Brown, Ill. Conch. G. B. pl. 56, f. 1) in the Linnean collec- 
tion: they cannot, however, be regarded as of typical authority, 
since no record is preserved of our author’s possession of 
examples, and were probably introduced subsequently to the 
publication of the ‘Systema.’ They correspond more aptly to 
the terms ‘‘levi” and “erectiuscula” than to the expressions 
“minuta,” “tam parva, &c.,’ which latter remind one rather of 
a Cecum: the members of that genus, however, not being per- 
forated posteriorly, would not answer to the generic definition. 
It seems to me, then, that, although from the inadequacy of the 
definition the name minutum cannot be retained, the species 
may be referred with doubt to D. gadus, a representation of 
which could not easily have been cited at that period.

The great majority of the Linnean Serpule are mere cases 
of Annelides, which are scarcely ever distinguishable with cer- 
tainty by the calcareous portion only. It is not my intention, 
then, to bestow the same serious attention upon them as I have 
upon the true shells, but merely to contribute such trifling in- 
formation as may be gleaned from the cabinet and manuscripts 
of Linneus.

In the revised copy of the ‘Systema,’ page 61 and figure 22 
of Martini’s first volume have been referred to as illustrative. 
The quoted engraving is a mere copy from the wretched drawing 
of Plancus that was cited with doubt in the published synonymy. 
Although, from the concluding words of the description, it is
