The L. tornatellina, Lowe, has hitherto been looked upon 

 as essentially peculiar to the Madeiran archipelago, where how- 

 ever it is more widely diffused than most of the other members 

 of the genus, — inasmuch as it is found for certain on at any 

 rate four out of the five islands, if not indeed on them all ; and 

 it is therefore with some surprise, despite this latter fact, that I 

 have examined lately a single individual which was taken a few 

 years ago by Mr. Watson, without any doubt whatsoever, in 

 Grand Canary. From a topographical point of view, the im- 

 portance of this specimen (which I have inspected with the 

 greatest care) can hardly be overrated, — for it introduces into 

 the fauna of the present Group not merely an additional species, 

 but an exponent of a Section of the genus Lovea (namely 

 Anvphorella, Lowe) which had not been observed hitherto 

 except at the Madeiras. It must however be of considerable 

 rarity in the Canarian archipelago, — this being the first 

 instance, so far as I am aware, in which it has been met 

 with. 



sole purpose of collecting shells and plants. There is consequently no single 

 link wanting in the evidence to show that these two Achatinas (the Paro- 

 liniana and Tandoniana) which have puzzled naturalists through so many 

 years are, in reality, not Canarian at all, but nothing niore than the L. triticea 

 and oryza, of Lowe, which had been taken by Webb himself in Porto Santo in 

 1828, and which were carelessly mixed up with his Canarian material which 

 had shortly afterwards to be investigated in order to compile his ' Synopsis ' 

 of the Land-Mollusca of that Grourj. As for his specification of the three 

 Canarian islands in which he is supposed to have met with the ' Achatina 

 Paroliniana ' (made up of the L. triticea and oryza of Porto Santo), it is quite 

 evident that he confused the habitat with that of some other shell ; and as 

 for Mousson's assertion that he found ' un seid individu, mort. et mutile ' of 

 the Tandoniana amongst Fritsch's material from Lanzarote, it must be taken 

 for what it is worth,— seeing that he had no knowledge whatever either of 

 that species or of the Paroliniana, the published diagnoses of which he 

 simply copies.
