374 WATSON : MARINE MOLLUSCA OF MADEIRA. 



the figure given by Dunker in his ' Mollusca of Guinea ' 

 give one much confidence in the species. 



Mytilus edulis Lin. Funchal. Of this I have spoken 

 above. Mr. Lowe got none of it. A few shells, young 

 and dead, with a broken valve larger, were dredged by me 

 in Funchal Bay, deep. A specimen now and then was 

 brought to me for sale. 



Chama gryphina Lam. ' Funchal.' Only one Chama — C. 

 gryphoides Lam. — but that plentifully, presented itself to 

 Mr. Lowe or myself. It is curious that Mr. McAndrew 

 did not get it. The identity of C. gryphina with C. 

 gryphoides Lam. has been abundantly shown by that most 

 competent judge Mr. Searles Wood, ' Crag. Moll.' ii., 162. 



• Cardium paucicostatum Lk.=C. ciliare Auct: Some 

 accidental slip of the pen has occurred here, Lamarck has 

 no species of this name and Sovverby's C. paucicostatum is 

 accepted as a synonym for C. echinatum L., which Senhor 

 Nobre has given as the immediately preceding species in 

 his list. 



Cardium exiguum Gmel. 'Dredged at Canigal.' The 

 locality here given was little likely to have been disturbed 

 by ballast discharges, and the species must perhaps be 

 accepted, though not without hesitation. 



Venus fasciata DaCosta. ' Dredged at Funchal and at 

 Canigal.' The same remark will apply here as to the 

 preceding. 



Tellina serrata Brocchi. 'Dredged at Funchal.' The locality 

 here makes it impossible to receive this species without 

 confirmation, though its distribution makes its occurrence 

 ■ far from improbable. 



Psammobla ferroensis Lamarck. 'Dredged at Cani^al' 

 (for Lam. read Chemn.). 



Mesodesma cornea Poli. ' Dredged at Canigal' The dis- 

 tribution of both these species, as well as the locality given
