LIMAX. 207 



Var. nrFESCENS, Pini (fig. 93)= var. ornata, Paulucci. Yellowish 

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



Var. RETICULATUS, Miill. (fig. 94). Brownish, with darker spots 

 on the shield, and linear dark maculations or reticulations 

 on the body. 



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

 shield sometimes subi'asciate. 



Var. VERANYANUS, Bourg. (fig. 96). Ash-colored, with small 

 black punctations. 



Var. 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, Xormand (= = orna- 

 tus, 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, 

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



L. Dymczewczii. Kaleniczenko (fig. 98), is, as Lessona and 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 

 shorth T 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, graj'ish diaphanous 

 in the middle ; mucus watery. 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.
