The common European A. albipes abounds in damp spots generally 

 (particularly along the edges of the streams) in Madeira proper, and 

 also in Fuerteventura of the Canarian Group ; but it is somewhat 

 remarkable that, although thus universal in those two islands, it has 

 not yet been observed elsewhere throughout the archipelago.

Habitat Maderenses (Mad.) et Canarienses (Can., Ten., Gom.), in

The A. marginatus, so universal throughout Europe, occurs spar-

 the Canaries where it has been detected in Grand Canary, Tene- 

 riffe, and Gomera.

Apparently peculiar to the Desertas, of the Madeiran Group, oc- 

 curring on the summits of the two southern islands the Deserta 

 Grande and the Bugio ; but it has not yet been observed on the 

 northern one, or Ilheo Chao. In the ' Ins. Mad.' I regarded it as a 

 large, insular modification of the 0. maderensis in which the colour
