TYPE SHELLS FROM THE CANAUIES. 523 



stantial evidence, which is strong, bnt also on a letter of Mr. 

 Webb's, who wrote (in 1830) : — " The reason why many of the 

 shells I sent are in a bad state is that they are collected hij the 

 fishermen on the opposite continent of Africa.'''' Mr. Lowe, accord- 

 ingly, referring this specimen and those of D'Orb. to the F. ruhi- 

 nosa, var. /3. incurva, gives as its " Hab. Mogador and coast of 

 Africa, opposite Lanzarote. "Webb ; Lowe." 

 Neither of these species is Madeii'an. 



" 26. Buccinum olearium, nob. Ilurex olearium, L. Can you 

 not get me a live specimen of this size ? " 



D'Orbigny publishes this as the Tinton pileare of Linn, acd 

 Gmelin, and gives T. succinctus, Lam., as a synonym. It seems 

 generally admitted that T. pileare is a different species, from tbe 

 Indian Ocean, and that T. succinctus, Lam. = 2^. olearium (Linn, 

 part), Desb., must give place (see Weiukauff, Conch, d. Mittel- 

 meeres, ii. 77, and Monterosato, Notiz. i. a. Concbiglie Mediterr.) 

 to the older name given by V. Salis, of T. parthenopeus. 



It is also Madeiran in a dwarf form. 



Along with this specimen is another shell in bad condition, wbicb 

 Mr. Lowe had evidently accepted as the same species. I believe 

 it to be a large form of a Madeiran species, which I propose to 

 publish as new under the name of T. anceps. 



" 27. Triton nodiferiim, Lamk." 



Thus given by D'Orbigny. It is also Madeiran. 



" 28. Haliotis tuberculata.^'' 



Thus given by D'Orbigny. It is also Madeiran. 



" 29. Patella solida, nob. ; P. aspera, Lam. ? Plentiful in 

 Madeira." 



The paper thus numbered and named by Mr. Lowe contains 

 two shells, of which the one is P. Loioei, D'Orb., = P. aspera, 

 Lam.; and the other is P. caerulea, Linn., = P. crenata, Gmel. 

 Both are common in Madeira. 



There is a great deal of confusion regarding the synonymy of 

 these two ; but without going into that question, and without 

 discussing the correctness of D'Orbigny's names for them, this 

 is certain, both from the shells and from the animals both in 

 Madeira and in the Canaries, that there are two well-marked 

 species demanding tlie recognition of distinct names, and that 

 D'Orbigny has done well to distinguish them. If the names
