universal, Grand Canary (where, however, we may be quite sure that 

 it exists) being the only island of the seven in which it does not 

 happen to have been observed. In the other six islands of the archi- 

 pelago, indeed, I have myself captured it, and in some of them it has 

 been taken likewise by others. And I even met with it on the little 

 rock of Lobos (in the Bocayna Strait), off the north of Fuerteventura. 

 It occurs in many different situations (under the bark of Euphor- 

 bias, and elsewhere) from the sea-level to an altitude of at least 

 8000 feet ; and it varies from a brightly maculated to a pale-ferru- 

 ginous state.

The common European C. serrata has probably been naturalized 

 in these islands from more northern latitudes. It occurs principally 

 about cultivated grounds and beneath the refuse at the base of corn- 

 stacks, though it has likewise established itself in less inhabited 

 districts. In such situations it is found in Madeira proper, as also 

 in Lanzarote, Fuerteventura, Teneriffe, and Hierro, of the Cana- 

 rian Group. It will most likely, however, be met with almost uni- 

 versally if searched for in the proper localities. 



427. Corticaria inconspicua. 



Corticaria inconspicua, Woll., Ann. Nat. Hist. v. 260 (1860).

Found in Madeira proper, about out -houses and cultivated grounds 

 much in the same way as the last species, to which, indeed, it is 

 very closely allied. I scarcely think, however, that it can be a small 

 or depauperated state of the serrata ; for its characters (such as they 

 are) seem to remain constant. It has been met with around Funchal, 

 and at S. Antonio da Serra ; but it is the former district in which it 

 has been observed most plentifully, it having occurred in abund- 

 ance, amongst some old bones, in Mr. Leacock's garden at the Quinta 

 de Sao Joao.
