MARINE MOLLUSCA OF MADEIRA. 273 



G-wyn Jeffreys, Brit. Conch, v. 5, i. 1 & xcvii. 1. Sab. From 

 Norway (see Sars, Moll. Norv. p. 363) to the Mediterranean 

 and Canaries. (M., W.) From Funchal eastwards, 10 to 

 50 fms. Not uncommon. 



16. Aplasia ocellata, 1839, d'Orbigny, Moll. Canar. p. 44, v. 1-4. 



Sab. Canaries. ( W.) From west of Funchal to the extreme 

 E. point of the island, from the shore to 50 fms. Many 

 young shells. — Mr. Pilsbry (Manual, 1st ser. xvi. 76) adopts 

 A. daciylomela, Rang, for this species, but gives no expla- 

 nation of his passing-by d'Orbigny's express statement that 

 they cannot be united — a statement he would not have 

 made hastily. 



17. Area diluvii, 1802, Lamarck, Ann. Mus. vi. 219 ; An. s. Vert. 



1819, vi. (1) 45, 2nd ed. (1835) vi. 476, note of Deshayes; 

 Philippi, Enumeratio, I. 59 (as A. antiqaata), n. 43, pi. v. 2. 

 Sab. Mediterranean to Canaries. (W.) Funchal, 50 fms. 

 3 separate valves. — On the strength of the habitat I admit 

 this species, but with the gravest doubt. 



18. Area nodulosa, 1776, Muller, Zool. Dan. Prod. p. 247 : Gwyn 



Jeffreys, Brit. Conch, n. 180 ; & v. 176, c. 2. Sab. From 

 Norway to the Mediterranean and Adriatic. (L., Jn.) A few 

 living specimens from 10 to 30 fms., dredged in Labra near 

 the extreme E. point of the island. 



19. Area pectunculoides, 1834, Scacchi, Ann. Sicil. VI. 82 ; Phi- 



lippi, Enum. II. 44, xv. 3 ; Forbes & Hanley, Brit. Moll, (as 

 A. raridentata) n. 241, xlv. 8. Sab. From Greenland to 

 Mediterranean. (Jn.) One specimen, with the valves 

 united. 



20. Area plieata, 1795, Chemnitz, Conch.- Cab. XI. 244, cciv. 



2008 ; Beechey (as A. gradata), Voy. ' Blossom,' p. 152, 

 xliii. 1; E. A. Smith (as A. domingensis, Lam.), ' Challenger ' 

 Lamellib. p. 265. — Lischke traces this species (as A. domin- 

 gensis, Lam.) under most of its synonyms from Japan to 

 Australia, to Natal, to the S. Pacific, to Panama, to the 

 West Indies, the Bed Sea, and the E. coast of Africa. In 

 the face of such a record I have not the courage to 

 refuse right of citizenship in Madeira to the two rather 

 undergrown, much weathered, but still quite recognizable 

 specimens which I got from deepish water at Punta de 

 Sao Louren§o, the eastern point of Madeira, and which 

 alone represent the species in the island.
