534 Mr. W. S. Macleay'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- 

 veUina. It is not, however, as Captain Sabine supposes, the Asci- 

 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 Brugui^res's 

 figure of his A. pedunculata as a synonym for his A. globifera. 

 This, however, is no error of Lamarck ; for the synonym is cor- 

 rect, but unfortunately, Brugui^res'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 Bruguiferes's figure rather than in that of 

 Lamarck's synonym. 



With respect to the Ascidia pedunculata I may observe, that not 

 only Brugui^res's figure of it in the Encyclopidie MSthodique, 

 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 Linnaeus. Dr. Shaw's 

 figure of it is merely a reversed cop^'^ 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 Bruguieres and Shaw, with the 

 Vorticella ovifera of Linnaeus, 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.
