Likewise a Canarian species, but one which. I have observed 

 hitherto only in the island of Palma where it is far from uncom- 

 mon, beneath stones.

Next to the H. tristis this appears to be the most widely spread 

 of the several Hegeters here enumerated ; nevertheless hitherto it 

 has been observed only in the Canarian Group. It is a variable 

 species, having many slightly different states, or races, most of 

 which however merge gradually into each other, and all of which 

 rest on characters extremely superficial and unimportant. It is 

 locally abundant in Teneriffe, Gomera, and Hierro ; and if the H. 

 glaber should prove eventually to be but an insular modification of 

 it (which I consider far from improbable), it will then have been 

 detected in Palma likewise. 



1090. Hegeter transversus.

Habitat Canarienses (Ten.), in intermediis et rarius in inferioribus 

 occurrens, in illis statum majorem latiorem (a.), sed in his mi- 

 norem (ft.) efficiens. 



A Canarian Hegeter which has been observed only in Teneriffe, for 

 the most part on the northern side of the island, where it ranges 

 from the sea-level to an altitude of about 4000 feet ; but it is 

 towards the upper of those limits that it attains its maximum, be- 

 coming gradually larger and broader as it ascends. This change in 

 its outward contour is very perceptible if we trace it from the Puerto 

 Orotava (where it is comparatively small) up to the damp sylvan re- 

 gion of the Agua Mansa, or (though somewhat less conspicuously) 

 to that above Ycod el Alto*. 



* In M. Hartung's volume, the H. transversus is cited for Fuerteventura ; but 

 this is clearly a mistake the result either of his having omitted (as in numerous 

 other cases) to preserve his habitats with sufficient precision, or else of an error 

 on the part of Dr. Heer (who compiled the list) in regarding some truly Fuerte- 

 venturan species (such, for instance, as the Thalpophila plicifrons, to which it 

 bears a considerable primd facie resemblance) as identical with it.
