448 SPECIES OF THE SYSTEMA. 
were alike referred to, will only apply to the latter, from which, 
in all probability, the characteristic was deduced; yet neither 
“curvata,” nor the attached diagnosis are applicable to that 
shell. It is not unworthy of notice that class 1, part 2, 
genus 3, of Gualtier’s arrangement is equivalent to the modern 
limits of Vermetus proper. 
Serpula angutiwa. 
Born rightly decided that the form b was essentially distinct 
from the typical one; he has gravely erred, however, in trans- 
ferring the name anguina to the supposed variety, and bestowing 
the new appellation muricata upon the type, more especially as 
the latter, even before the publication of the ‘Systema,’ had 
been termed Solen anguinus by Rumphius, was an Indian shell 
(‘ Habitat in India’’), and had a somewhat articulated or inter- 
rupted fissure, as declared by Linneus, whilst the one preferred 
by himself was European, and had the slit continuous or un- 
interrupted. The peculiar fissure is insisted upon, also, in the 
‘Museum Ulricas’ where it is declared to be “ passim con- 
catenata, et quasi poris pertusa:” yet, strange to relate, the 
variety in that work is the prickly one. This combination of a 
punctured fissure with a merely wrinkled (“ rugz transversales,” 
M. U.), unarmed tube, is found in the Siliquaria Australis of 
Quoy; even as a muricated tube conjoined with a simple 
fissure is characteristic of S. squamata (Chenu, Ill. Conch. Sil. 
pl. 2, f.12). I do not consider, then, that the Mediterranean 
anguina (of Born) was indicated as the typical form in either 
the ‘Systema’ or the ‘Museum:’ at all events, it was not in 
the former, which (ed. 10) has priority. The three first species 
just mentioned are present in the Linnean collection. Gualtier’s 
figure (misprinted H in the ‘ Museum’), though it looks like a 
Siliquaria, appears from the text “notulis nigris punctatis” to 
_ be simply dotted with coloured markings; the drawing of Lister 
(548, f. 2, in the revised copy) and the figure 2 of Rumphius 
represent upper portions only, and are very uncharacteristic.
