TRITON.— Plate VIII. 



distant resemblance to Triton femorale, and there was a 

 specimen in the Tankerville collection marked No. 1718 

 in the Catalogue as a variety of that species in these 

 terms : var. notabilis, latissima, aperturd expansd. This 

 resemblance is greater in dwarfs than in well-grown in- 

 dividuals ; but the length and shape of the spire, the 

 comparative smoothness, the breadth of the ventricose 

 body-whorl, the expanded aperture with its rich orange 

 mouth, variegated towards the border of the outer lip 

 with dark chestnut stripes in pairs, and the shortness of 

 the canal, indicate that Triton tigrinus is very distinct 

 from Triton femorale ; and Mr. Sowerby, who drew up 

 the Tankerville Catalogue, is now of that opinion. The 

 throat or internal part of the aperture is of a blueish 

 white, and as in the rest of the species, the outer lip, and 

 consequently the varices, acquire a greater thickness as 

 the shell advances in age. The epidermis is peculiarly 

 foliaceous upon the varices and edge of the outer lip."

This is one of those species which is exactly interme- 

 diate between the genera Triton and Ranella ; I retain 

 it, however, in the former genus on the testimony of 

 Deshayes, who says " pour nous, qui enavons vu I'animal. 

 cest un Triton."
