320 COCHLICOPA. 



Var. fusiformis Picard. Shell as long as in typical lubrica, 

 6-7 mm., but much narrower, not at all swollen, all the whorls 

 diminishing insensibly (' ' Achatina lubrica var. a. H. fusi- 

 formis" Picard, Histoire des Moll. terr. et fluv. qui vivent 

 dans le departement de la Somme, in Bull, de la Soc. Lin- 

 neenne du nord de la France, i, 1840, p. 243). This form 

 has not been adequately defined. It may be related to 

 columna Cless., but no exact proportions are given by Picard, 

 whose description is translated above. He does not give the 

 exact locality in the Department of Somme. 



\d. C. LUBRICA MADERENSIS (Lowe). PI. 49, figs. 45, 46. 



Shell narrower, more slender and cylindric than C. lubrica,, 

 the aperture comparatively shorter. The last whorl often as- 

 cends slightly to the aperture. The columella is concave 

 above, slanting below and usually a trifle sinuate at base. 

 The outer lip has a moderate or strong internal rim, and 

 usually arches forward a little in the middle. Length 5.4, 

 diam. 2.1 length of aperture 2 mm. ; whorls S 1 /^. 



Madeira : suburbs of Funchal, etc., generally distributed.

This seems to be a well differentiated subspecies. In re- 

 cent years, the ordinary European C. lubrica has also been 

 imported to Madeira, where it exists in some localities. Fig. 

 45 is from an example from the suburbs of Funchal, 400 ft. 

 elevation. Fig. 46 represents a small, thinner shell from 

 Punta Sao Lourenco. 



The form from the Azores Archipelago figured on pi. 49, 

 fig. 44, is more robust than m,aderensis, scarcely to be distin- 

 guished from small lubrica. It has been described as Glan- 

 dina azorica Albers, Zeitschrift fur Malak. ix, 1852, p. 125, 

 type loc. San Miguel. "Length 5.5, diam. 2.5, aperture 

 2.5 mm."
