376 WATSON : MARINE MOLLUSCA OF MADEIRA, 



Ranella gigantea Lam. L"= and W. Rare. 



Bufonaria scrobiculata (a slip for tor) L. L^ and 



W. Common. 

 Purpura haemastoma L. ' Funchal.' 1/ and W. Very 



common. 

 Coralliophila mayendorfi Calc. 'Funchal.' L" and W. 



Abundant. 

 Marginella philippi Montero. This is a species I have not 



met with in Madeira. 

 Olivella leucozonias Gray. 'Funchal.' Weinkauff, Conch. 



Cab. 2d edit. p. 137, identifies this with O. pulchella 



Duclos, for which he claims priority. I do not know it as 



Madeiran. 

 Conus mediterraneus L. 'Funchal.' MacAndrew gives 



this as frequent in the Canaries, and I have bought it from 



boatmen, but never believed it to be Madeiran. 

 Ringicula someri de Folin. 'Funchal.' I do not know 



this species. 

 Roxianella Jeffreys! Weink. ' Funchal and Canigal.' W. 



Common. 



Out of these thirty-three, then, I reject three, which are to 

 me quite unknown, and suggest nothing among the species 

 found either by Mr. Lowe or myself, \\z.:—Pecten loivenii Dkr., 

 Cardium paucicostatuvi Lam., and Ringicula someri de Folin. 



Fourteen species seem to me so far doubtful, as having 

 never presented themselves throughout many years of dredging 

 to either Mr. Lowe or myself, and as wanting some further 

 details of information from Senhor Nobre, viz. : Peden varius L., 

 Mytilus edulis L., Cardiiivi exigtmm Gmel, Venus fasciata Da 

 Costa, Tellina serrata Broc, Psaminobia ferroetisis Lam., 

 Mesodesma cornea Poll, Scalaria communis Lam., Natica flain- 

 niulata Req., Natica alderi Forb., Natica josephinea Risso, 

 Litorina punctata Gmel., Marginella philippii Mont., Olivella 

 leucozotiias Gray.
