LIMAX. 207 



Yar. KUFESCENS, Pini (fig. 93)= var. ornata, Panlucci. Yellowish 

 or reddish brown, with a few dark spots and maculations. 



Yar. RETICULATUS, Mull. (fig. 94). Brownish, with darker spots 



on the shield, and linear dark maculations or reticulations 



on the body. 

 Yar. TRISTIS, Moquin-Tandon (fig. 95). Unicolored brownish, 



shield sometimes subfasciate. 

 Yar. YERANYANUS, Bourg. (fig. 96). Ash-colored, with small 



black punctations. 

 Yar. FLORENTINUS, Lessona and Pollonera. Larger, whitish, 



elegantly maculated with brownish black. 



In addition to the above there are varieties obscurus, lilacinus, 

 and ornatus, Moquin-Tandon ; punctatus, nigricans and varians 

 of Westerlund ; succineus, Miiller ; minutus, Kalenicz. (fig. 97), 

 from the Caucasus; saxorum, Baudon ; falvus, Normand (=orna- 

 tux, Moq.); sylvaticus, Drap.; nemorosus, Mabille. 



It is useless to attempt to correlate these various forms. 



L. varians , A. Adams (unfigured),from Japan, and L. molestus, 

 Hutton, New Zealand, are probably both to be included here. 



L. Dymczewczii. Kaleuiczenko (fig. 98), is, as Lessona ancT Pol- 

 lonera remark, " as like as two drops of water to L. agrestis" 

 and notwithstanding some small differences in dentition I am 

 disposed, for the present, to consider it a synonym. 



L. PALLIDUS, Schrenck. PI. 51, fig. 99. 



Small, moderately rugose, attenuated behind, plainly but 

 shortly carinate, the carina subtruncate ; shield large, subgibbose, 

 rounded behind ; pulmonary aperture posterior, light margined, 

 with a brown zonule above it ; color light ash or ochraceous, uni- 

 colored, or brown-maculated; tail, shield and neck yellowish; 

 oculiferous tentacles brownish ; sole whitish, grayish diaphanous 

 in the middle ; mucus wateiy. Length, 1-1*5 inches. 



Norway, Livonia, Northern Italy. 



Considered by several good conchologists a variety of L. agres- 

 tis. Lessona and Pollonera distinguish it by its smaller size, 

 uncolored and transparent mucus, and by characters of its den- 

 tition and anatomy ; its habitat is also different, preferring forests 

 and shaded, humid localities.
