generally, at a considerable depth underground, about the roots of 

 various shrubby ])lants (particuhirly tlie Zijgop////Uuin Fontancsii, 

 Webb, and a small Euphorbia) which stud the dry barren sandy 

 tracts of Fucrteventura, Lanzarote and Grand Canary, and around 

 which solid Iiillocks have gradually accumulated from the loose 

 surface-sand, which the constant breezes of those latitudes keep 

 in an eternal state of drift. In such situations, by selecting a 

 mound and scooping a large hole at the side of it (so as to catch 

 everything that might chance to fall), and then laying bare the 

 roots and stems immediate!}' above it, I have at times taken the 

 Pentntcmnus in tolerable jirofusion — especially on the arid wastes 

 in the vicinity of Porto de Cabras of Fucrteventura, and on th.ose 

 far more extensive ones at Corralejo (the extreme northern point 

 of the island). In like positions I have found it, though more 

 sparingly, near Arrecife, of Lanzarote, and at Maspalonias, in the 

 south of Grand Canary.
