310 EEV. E. B. WATSON ON THE 



of R. concinna lie bad given it was preoccupied by Searles 

 Wood for a different species ; and in tbat belief in bis 

 * Nomenclatura,' 1884, p. 66, be cbanged the name of bis 

 Mediterranean species to R. beniamina. But R. concinna 

 was a mere catalogue-name wbich Searles Wood, wben be 

 came for tbe 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 ^ie^ff but for the fact that 

 Monterosato rejects my identification of the Madeiran 

 species with his from the Mediterranean. Tbe 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.

Sissoa {Alvania) Montagid, 1826, Payraudeau, Moll. Corse.— One speci- 

 men which I got in Funchal Eay, 50 fms., the ordinary anchorage 

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

 of this species found in Madeii-a ; 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.
