310 BEV. E. B. WATSON ON THE 



of R. concinna he had given it was preoccupied by Searles 

 Wood for a different species ; and in that belief in his 

 ' Nomenclatura,' 1884, p. G6, he changed the name of his 

 Mediterranean species to R. beniamina. But R. concinna 

 was a mere catalogue-name which Searles Wood, when he 

 came for the first time to describe the species, replaced by 

 a true specific name, viz. R. punctura. R. concinna thus 

 remains as the name of Monterosato's Mediterranean 

 species. That name therefore I should have adopted here 

 for the Madeiran species now in view but for the fact that 

 Monterosato rejects my identification of the Madeiran 

 species with his from the Mediterranean. The material 

 for a thorough independent opinion I do not possess, and 

 I am content to accept the judgment of an authority 

 in every way so trustworthy — compelled, however, in these 

 circumstances to propose for the Madeiran species the new 

 name I have given above.

Rissoa {Alvania) Montagui, 1826, Payraudeau, Moll. Corse. — One speci- 

 men which I got in Punchal Bay, 50 fms., the ordinary anchorage 

 and discharge for ballast, is, so far as I know, the only representative 

 of this species found in Madeira ; and I stated in P. Z. S. 1873, p. 390, 

 that I did not on such evidence regard it as Madeiran. Weinkauff, 

 however (Conch.-Cab. 2nd ed. i. pt. 22, p. 114), gives it as Madeiran, but 

 without quoting any authority. It ought not without further evidence 

 to reckon as Madeiran.
