half less than H. crystallina, and one more than //. cellaria of 

 the same size.

3. H. concinna.

 nata aperte et sat large perspectivo-umbilicata sericeo-nitidiuscula

Certainly distinct from H. engonata and retexta, Shuttl. ; and 

 equally so apparently from H. scutula, Shuttl. (Diagn. i. 5), of 

 which, however, I have not seen a specimen.

4. H. nubigena. 



T. umbilicata depressa orbiculato-subdiscoidea subcarinata subpel- 

 lucida tenuiuscula hispidula fusca atro (intus) plerumque punctu- 

 lata V. maculata ; spira convexo-depressa, anfr. 4 convexiusculis, 

 sutura distincta impressa ; umbilico majusculo cylindrico subspi- 

 rali profundo ; apert. oblique lunato-ovali ; perist. simplici tenui 

 acuto. 



Diam. maj. 5, min. 4^, alt. 2^ mill. Anfr. 4. 



Hab. sub lapidibus ad radices "Retamce" (^Cytisi nubigeni. Ait.), 

 in excelsioribus " Cumbre v. Canadas " dictis montis " Pico de 

 Teyde" Tenerifee, Maio 1859, T. V. Wollaston. 



An obscure insignificant species, without sculpture, and pos- 

 sessing no very distinctive or striking character of any sort : 

 nearest undoubtedly to H. hispida, L., and its allies, but a little 

 reminding one of H. conspurcata, Drap., from which, however, 

 it is totally distinct. 



None of my examples appear perfectly adult; but I am not 

 acquainted with any Canarian species of which they can be the 

 young ; for it is perfectly distinct from the young of H. hispidula, 

 Lam., for which it might easily be mistaken.
