MARINE MOLLUSCA OF MADEIRA. 307 



265. Ranella Thomce, 1853, d'Orbigny, Moll. Cuba, n. 164, xxiii. 



23. Bab. Islaud of St. Thomas, W. Indies. (Jn., W.) 

 Puuta de Sao Lourengo and Porto Santo ; 5 full-grown 

 (3 living) and 4 young shells. There are 2 specimens 

 in the Brit. Mus. from the Cape Verd Is. — I have failed 

 to trace this species to 1846, to which year d'Orbigny 

 ascribes it. It does not occur in his Arner. Meridion. For 

 note on the species, see "Watson, ' Challenger ' Eeport, 

 p. 400. 



266. Ringicula auriculata, 1811, Menard (as Marginella), Ann. 



Mus. xvn. 331; Philippi, Enumeratio, i. 231, n. 198, 

 xxviii. 13 ; Morelet, Jour, de Conch. 1878, p. 275, v. 14 ; 

 Watson, Jour, de Conch. 1878, p. 312, x. 4. Hob. Bay of 

 Biscay to Mediterranean. (M., L., N., Jn., W.) Every- 

 where ; extremely abundant. 



267. Ringicula Someri, 1867-71, de Eolin, Eonds d. 1. Mer, 



I. pt. 1, p. 14, i. 7 ; Morelet, Monog. Eingicula, Jour, de 

 Conch. 1878, p. 128, v. 8. Hob. Cape Verd Is. (N.)— 

 I give this species entirely on the authority of Senhor 

 Nobre. It is one I have not seen, and of which I cannot 

 judge. Among the very great number of specimens of 

 Ringicula collected in Madeira I have never seen any 

 variety on which to found a species, and indeed the 

 peculiarities obvious in the figures of R. Someri are 

 exactly those of the immature shell of R. auriculata.
