Habitat Canarienses (Lanz., Fuert.), in locis similibus ac prae- 

 cedens. 



Found in Lanzarote and Fuerteventura, where it would appear to 

 take the place of the H. eremita which is so widely diffused over the 

 more central and western parts of the Canarian archipelago. This 

 being the case, it is almost impossible to resist the inquiry as to 

 whether the calvus may not in reality be but a modification of the 

 (essentially variable) eremita peculiar to those two eastern islands. 

 Without wishing to record my belief that such is by any means im- 

 possible, I will merely add that I have given the reasons, in my 

 Canarian Catalogue, why I think it is more likely that the calvus is 

 a truly distinct (though nearly allied) species. 



927. Herpysticus oculatus. 



Herpysticus oculatus, Woll., Cat. Can. Col. 373 (1864). 

 Habitat Canarienses (Lanz.), in intermediis aridis calcariis degens. 



Observed hitherto only in Lanzarote, of the Canarian Group, 

 where it occurs beneath stones in dry calcareous spots of interme- 

 diate altitudes ; but we may expect to meet with it in Fuerteventura 

 likewise. 



The remarks under the preceding species are perhaps equally ap- 

 plicable here ; for the H. oculatus bears much the same kind of 

 relation to the calvus that the latter does to the eremita.
