282 ABIDA. 



Catalonia in Spain. The group is prolific in species or local 

 races, but few of them have been figured, and no general re- 

 vision which inspires confidence has been published. 



11. ABIDA AFFINIS (Rossmaessler). PI. 44, figs. 5, 6. 



Shell having an oblique rimation close behind the columellar 

 lip, cylindric, tapering above and below, horn-brown, with 

 hair-like strias and therefore a satiny luster, thin, translucent. 

 Whorls 11, rather convex, very slowly increasing, the last 4 

 of almost equal height, the last twice the height of the penult ; 

 suture somewhat impressed. Aperture almost ovate, higher 

 than wide, peristoine discontinuous, but little reflected, white- 

 lipped, weakly angular below; columellar margin rather 

 straight, shorter than the somewhat inwardly bent outer mar- 

 gin. On the parietal wall close to the outer margin there is a 

 long, entering fold, doubled in front by a little fold close to it. 

 Columella with 2 indistinct folds ; in the palate two very long 

 folds, reaching from the peristome deep into the throat, one or 

 two quite small folds standing above the inner end ; below the 

 two long folds in front may be seen a short fold, then inter- 

 rupted, and appearing again farther back; so that upon the 

 neck one may see two long white streaks in the middle, and 

 backward, above these, one or two short streaks, and below 

 them one short fold in front and one behind. Length 4%, 

 diam. l 1 /^ lines (Rossmaessler). 



Some of my examples have the two long palatal folds in- 

 terrupted, and the two lower folds concrescent into one long 

 fold (Rossm.}.
