534 Mr. W. S. MacrEAY's Anatomical Observations 
of science remarks, the Ascidia clavata of Otho Fabricius, but not 
that of Pallas, which now forms the type of Savigny's genus Cla- 
vellina. It is not, however, as Captain Sabine supposes, the 4 sci- 
dia globifera of Lamarck, since the body of this species is sub- 
globose and not sub-reniform, as in the animal described by 
Captain Sabine and by Otho Fabricius. The mistake has ori- 
ginated in the circumstance of Lamarck citing Bruguiéres’s 
figure of his 4. pedunculata as a synonym for his A. globifera. 
This, however, is no error of Lamarck ; for the synonym is cor- 
rect, but unfortunately, Bruguiéres’s figure being a vile copy of 
a bad figure of Edwards, who has represented the branchial ori- 
fice of his Animal-Planta as somewhat simple and not quadrifid, 
as it ought to have been, Captain Sabine was induced to confide 
in the accuracy of Bruguiéres's figure rather than in that of 
Lamarck's synonym. 
With respect to the Ascidia pedunculata I may observe, that not 
only Bruguieres's figure of it in the Encyclopédie Méthodique, 
but also the one given by Shaw in the Zoological Miscellany, is a 
miserable copy of the above figure of Edwards's Animal- Planta, 
which is, as Dr. Shaw suspected, and as M. Savigny has shown, 
no other than the Vorticella ovifera of Linnzus. Dr. Shaw's 
figure of it is merely a reversed copy of Edwards's figure, retain- 
ing the same unnatural position and the same error, only more 
strongly marked, of the branchial orifice. 
Having thus ascertained the identity of Lamarck's Ascidia 
globifera with A. pedunculata of Bruguières and Shaw, with the 
Vorticella ovifera of Linnæus, and the Animal- Planta of Edwards, 
nothing remains to be said on its nomenclature, except that it is 
the Boltenia ovifera of Savigny, who has most ably explained its 
anatomical structure. 
It appears, therefore, that the animal now before me from 
Winter Island is not the true globifera of Lamarck, as may be 
ascertained on inspection of any of the above-mentioned figures.
