1880.] LAND-SHELLS OF MENTON. 103 



LiMAX, Sp. ? 



Mr. Coorabe Williams found a single specimen of a small black 

 Limax on the Bergeau at a great elevation. 



LiMAX (Krynickillus) niciensis, Bourg. 



Creamy yellow, mottled with pale brown (not very closely) ; sole 

 of foot and sides whitish ; head and neck concolor, fulvous yellow ; 

 orifice posterior ; crest rather distinct, also posterior rugosities and 

 circular striation of buckler, mucous white. 



Not uncommon near the village of Grimaldi. Mr. Williams also 

 found it at 3000 feet on the Berceau Mountain. 



Limax (Krynickillus) mentonicus, n. sp. 



Sole of foot light brown ; orifice posterior ; head and tentacles 

 dull claret-colour, very sparsely speckled with black ; buckler un- 

 usually long, rich brown, closely and minutely speckled with black, 

 circular striation apparently running in two contrary directions ; pos- 

 teriorly nearly smooth ; extreme caudal end acutely pointed, of a 

 brighter (speckled) brown colour. 



Common near Mentou. This Slug is very active. 



MiLAx GAGATES, Drap. 

 A common Menton Slug. 



MiLAX carinata(?), Risso. 



A rather uncommon species, from the Submaritime zone. 



MlLAX, sp. 



We found, subfossil, numerous specimens of various species of this 

 genus in deposits. 



MiLAx, n. sp.? 



Concolor, fulvous-yellow, minutely speckled with grey ; sole of 

 foot faint yellowish, undivided ; tentacles inky black ; buckler bi- 

 lobed posteriorly ; crest distinct ; orifice slightly posterior ; line of 

 "limacelle" rather indistinct. 



Village of Grimaldi. 



ZONITES ALGIRUS, LinUDBUS. 



Rather local near Menton ; only found at a level of 2000 feet 

 or so, especially in the neighbourhood of the higher-level road to 

 Nice, round the village of Roquebrune &c. I also found a single 

 perfect specimen on the side of the road round Cape St. Martin, 

 buried a few feet below the surface ; I imagine it had been washed 

 down from the mountains behind. I saw no trace of this species 

 subfossil, not even in the upper stratum of Cape Mortela, where I 

 should have expected to find it. The Menton form is more dis- 

 tinctly subangulate at the periphery than usual.
