TYPE SHELLS EKOM THE CA-NAKIES. 517 



specimens as among those which Mr. Webb had sent to Mr. Lowe, 

 and implies dissatisfaction at Mr. Lowe's retention of these, the 

 absence of which marred the completeness of his work. 



In 1860 Mr. Lowe published in the * Proceedings of the Linnean 

 Society' (Zoology, vol. v. pp. 169-204) a List of the Shells observed 

 or collected at Mogador &c., with most valuable notes and ob- 

 servations. In this paper Mr. Lowe makes very frequent refer- 

 ence to D'Orbigny (see pp. 171-174, 188, 189, 190, 197-199); 

 and the whole tone of these references shows that, apart from 

 indignation at the manner in which M. d'Orbigny had done his 

 work, Mr. Lowe resented keenly the way in which allusion had 

 been made to himself. 



In 1873 the * Liberia,' in which Mr. Lowe had sailed for Ma- 

 deira, disappeared utterly in the Bay of Biscay ; and Mr. Lowe's 

 accumulations of marine shells from Madeira, the Canaries, and 

 the Cape-Verds, which seem to have gone on from 1826, were 

 forwarded to me for publication by his executor, Mr. T. V. "Wol- 

 laston. Among these I have found the identical Canarian sheila 

 sent by Mr. "Webb, and Mr. Lowe's annotated Hst, which he had 

 sent back to Mr. Webb — in short, the very material which M. 

 d'Orbigny complained of Mr. Lowe's having retained, and the 

 information which Mr. Lowe objected to M. d'Orbigny having, 

 without acknowledgment, used. 



In the interests, then, of truth, as bearing on both these parties, 

 and as needed for the fuller knowledge of the marine MoUusca of 

 the Canaries, this list is of value *. It is as follows : — 



" Marine Mollusca from Grand Canaria, Lancerotte, and 

 Fuerteventura, sent by P. B. Webb, Esq. Oct. 29, 1829. 



" 1. Lucina petisylvanica. DiiFering in the entire, not crisped, 

 epidermis. Var. an sp. ? " 



D'Orbigny published this as L. Adansonii, D'Orb., remarking 

 that " Cette espece a, par ses lames, encore beaucoup de rapports 

 avec la L. pensylvanica ; mais une difference notable entre elles, 

 c'est que les lames sout recourbees du cote du sommet dans la 

 L. pensylvanica, tandis qu' elles le sont au coutraire dans I'esp^ce 

 qui nous occupe du cote de I'ouverture des valves," 



It is not found in Madeira. 



"2. Cardium tuberculatum.'^ 



This is so given by D'Orbigny. It is also found in Madeira. 



* Tlie shells theinselves I propose to deposit in the Britisli Museum.
