Habitat Maderam, vulgaris ; in Deserta Grrandi et Deserta 

 Australi, necnon in cacuminibus montium Portus Sancti, multo 

 rarior. In statu semifossili ad Canipal, Maderse, sat copiose 

 reperitur. 



This is the common Lovea in Madeira proper, where it is 

 well nigh universal ; and it occurs also, though much more 

 rarely, on the two Southern Desertas as well as on the summit 

 of the Pico Bran CO in Porto Santo ; and, like so many of the 

 members of the genus, it seems to present two or three 

 slightly different phases, which however merge into each other 

 by intermediate gradations. The Jirst of these, a [major], is 

 found principally in the sylvan districts of a comparatively 

 high altitude in Madeira proper, and is typically rather 

 large, ventricose, and highly coloured, with the subvertical ven- 

 tral plait elongate and narrow, and the columella a good deal 

 (and abruptly) expanded at the base ; the second, j3. [minor], 

 which is also common in Madeira proper,, but is more particu- 

 larly characteristic of the exposed submaritime cliffs, is, on the 

 average, smaller, and not quite so rounded, generally a trifle 

 paler in hue, with tlie subvertical ventral plait a little shorter 

 and more dentiform (or more abruptly terminated behind), and 

 with the columella not quite so broad ; whilst the third, 7. [in- 

 termedia], which is met with sparingij' on the two Southern 

 Desertas and on the summit of the Pico Branco in Porto Santo, 

 is somewhat intermediate in stature between the ' a ' and ' ;S,' 

 and has the subvertical ventral plait (although scarcely denti- 

 form as in the ' /S.') distinctly expressed and rather further 

 removed from the angle of the lip, and the inner medial tubercle 

 not altogether obsolete, — it being, although indistinct, quite 

 appreciable. These varieties, however, pass gradually into each 

 other, and are of too trifling importance to need separate sub- 

 specific titles. 



Three examples of this very abundant Madeiran Lovea were 

 taken in Porto Santo, by the Eev. R. T. Lowe, in 1828, — 

 namely on the summit of the. Pico Branco ; and it has been 

 obtained sparingly from the two southern Desertas by the Baron 

 Paiva.
