CANARIAN GROUP. 357 



Canary by Fritsch. It was probably a mistake of M. d'Orbigny's 



to have cited it from Gromera ; but most likely he was merely 

 guided by the references of Mr. Webb,— whose extreme in- 

 accuracy on the subject of habitats I have had occasion more 

 than once to dilate upon. I happen however to know that the 

 El Monte district was collected in for some time by Webb, so 

 that he could scarcely have failed to secure this large and con- 

 spicuous Helix. 



Even Mousson, who gave an emended diagnosis of this 

 species, has omitted to call attention to some of its most salient 

 features, — such, for instance, as the minute granulations with 

 which it is densely crowded (he even speaks of it as ' laevigata ' ! ), 

 and the pinkish purple tinge with which its peristome is con- 

 spicuously coloured ; and he also defines it as 4-fasciate, where- 

 as the number of its fascia? is most unmistakeably five, — two 

 being below the dorsal line, two (which are subconfluent) im- 

 mediately above it, and one adjoining the suture. 



In its rather obliquely-elongated outline, laterally-extended 

 aperture, and greatly developed, incrassated, recurved, pinkish 

 peristome, no less than in its solid substance and its densely- 

 granuled, 5-fasciated surface, the H. Gaudryi is a good deal 

 on the type of the H. sarcostoma ; nevertheless it is very 

 much smaller and more depressed (both above and below) 

 than that species (even though free from all indications of a 

 keel), and has a much livelier and more dappled coloration, — 

 the bands being broken-up by more or less angular yellowish 

 markings ; added to which there is no trace of an elongated 

 obtuse ridge-like tooth (formed by the scooping-out of the 

 basal margin) within the peristome, and it is generally more 

 appreciably malleated. It is, however, a variable shell, — the 

 malleations being often comparatively inconspicuous ; and even 

 the umbilicus is sometimes (though rarely) not completely 

 closed over. The larger examples of the H. Gaudryi measure 

 about 11 lines across their broadest part, and the smaller ones 

 about 8.
