SUPPLEMENT. 185 



" Keport on South European Marine Tnvertebrata," observed that 

 at Algiers the typical form inhabits the littoral zone, while the 

 form called striatula occurs only at a depth of 30 f. ; and in a 

 communication from him to Prof. E. Eorbes (Ann. N. H. 2nd 

 ser. in. p. 509) he says, with reference to his dredgings off 

 Cape St. Mary's in 15-30 f., " The Venus from that locality 

 appears to be intermediate between the yallina of the Medi- 

 terranean and striata [striatula] of our seas, so that they may 

 at last prove to be only varieties of the same species." Prof. 

 Romer has lately restored V. pallida of Turton as a species !
