WATSON : MARINE MOLLUSCA OF MADEIRA. 375 



for them, entitle them to pass as Madeiran, though not 

 without query. 



Trochus listeri Wood. ' Funchal.' This species is the T. 

 colubrinus Gould. The synonymy is discussed in the 

 ' Challenger Report,' p. 65. Wood's T. listen \s absolutely 

 beyond identification. 1/ and W. Very abundant. 

 Largely used for food ; its shells may be met with every- 

 where, inland as well as on the shore, so that its absence 

 from MacAndrew's list is singular. 



Trochus candei d'Orb. 'Funchal.' L^ and W. Common. 



Clanculus bertheloti. L^ and W. Common. 



Scalaria communis Lamk. 'Funchal.' Two specimens of 

 this species were given to me as obtained from fishermen 

 in Funchal Bay, and one other specimen was brought 

 under my notice as bought on assurance of its being 

 Madeiran, but I never regarded the species as indigenous. 

 It would need confirmation. 



Scalaria commutata Monterosato. 'Funchal.' L" and W. 

 This species has been generally accepted as S. pseiido- 

 scalaris Broc. 



Natica flammulata Req. 'Funchal' 



Natica aider! Forbes. ' Funchal' 



Natica josephinia Risso. 'Funchal' 



Litorina punctata Gmel 'Funchal' 



I have not heard before of any of these species being found 



in Madeira. 

 Cyprasa spurca Linne. 'Funchal' 1/ and W. Frequent. 

 Cassis saburon Bruguibre. 'Funchal' L^andW. Frequent. 

 Triton nodifer Lam. L^ and W. 

 Triton succinctus Linn, (a slip for Lam.). 'Funchal' L^ 



and W. T. parthe7iopus v. Salis is the synonym preferred 



by some. Hanley, in Wood's Index Suppl, p. 127, 



claims priority for Born's name of cosiatus.
