Mai 1876, p. 73. Have Dr. Cabanis and Reichenow compared the curious bird with Ptilopus insolitus, Schleg. Ned. Tijdschr. v. Dierk. i. p. 61, pl. iii. fig. 3 1 I suppose not, as otherwise they would not have failed to mention the great likeness which there appears to be between their bird and that of Schlegel. Ptilopus insolitus also has the base of the upper mandible swollen into a round ball; the colours are very much the same as those of CE. globifer, excepting that it has the smaller and also some of the greater and median wing-coverts and the last remiges, approaching the back, light grey. Schlegel had received his birds as from New Caledonia; but in the Museum des Pays-Bas, Columbce, p. 16, he has expressed his opinion that perhaps the type specimen of his Ptilopus insolitus was nothing else than a monstrous specimen of Ptilopus humeralis jobiensis ! It seems to me very probable that GEdirhinus globifer is identical with Ptilopus insolitus-a species which I shall have to add to the List of the Pigeons included in the second part of my " Prodromus Ornithologiae Papuar.se et Moluccarum " (Ann. Mus. Civ. Gen. ix. pp. 194-208). 8. Revision of the Anthobranchiate Nudibranchiate Mollusca, with Descriptions or Notices of forty-one hitherto undescribed Species. By PHINEAS S. A B R A H A M , M.A., B.Sc, F.R.M.S., F.Z.S. [Received February 20, 1877.] (Plates XXVII.-XXX.) Before the time of Cuvier but comparatively little attention been paid to the naked-gilled Mollusca. Linnaeus, in the earlier editions of his ' Systema Naturae,' alludes to Tethys, as a genus of the order Zoophyta ; in his 10th edition, 1758, the genera Doris (with one species) and Scyllcea first appear, and together with Tethys are included in the 4th order Molusca, of his 6th class, Vermes. He also diagnoses what we now believe to be Eolis papillosa, under the generic name Limax. In the 12th edition four species of Doris are scantily characterized, viz. D. verrucosa, D. bilamellata, D. Icevis, and D. argo. The second and fourth have been identified ; but of the remaining two we are not certain : D. verrucosa may be D. verrucosa of Cuvier; and D. Icevis may be D. repanda of Alder and Hancock. Linnaeus at first considered that the circumanal branchiae of Doris were oral tentacula ; he rectified his mistake, however, in his 12th edition, after the proper homologies of the parts had been pointed out by Bohadsch in 1761. In the 'Fauna Groenlandica,' published by Otto Fabricius in 1780, the foot of a Doris is described |
