138 AMPHIDROMUS, GROUP II. 



2 pale yellow, 1 dextral and 1 sinistral. 



6 reddish, 1 dextral and 5 sinistral. 



1 banded, dextral and 1 sinistral (" robustus " Fulton). 



The yellow ones are uniform colored, the white show traces of 

 streaks, the reddish have numerous decidedly-pronounced narrow 

 streaks of slightly darker, reddish-brown color ; and one specimen 

 (pi. 46, fig. 21) shows four sharply-defined and rather wide pale- 

 reddish spiral bands upon a white ground (this being Fulton's A. 

 robustus, see below) ; the variceal streaks are sometimes blackish- 

 brown, sometimes lighter brown. Transitions between those with 

 more evenly and those with more irregularly folded sculpture exist, 

 so that no division into two sets by this character can be made. 



If von Martens was right in referring the specimens commented 

 on above to the one species winteri, we can scarcely allow that A. 

 heerianus and A. robustus are specifically distinct. 



B. junghuhni is a museum name pertaining to this species, accord- 

 ing to von Martens. 

 Subsp. inauris Bttg.' Fulton. PI. 48, figs. 16, 17, 18. 



Umbilicate, oblong, wrinkle-striate or costulate and sometimes 

 malleate, pale sulphur-tinted or lemon, uniform, or yellow with red- 

 dish streaks, the darker color sometimes predominating. Peristome 

 flatly reflexed or recurved, broad, wider below.

 xvii, p. 74 (1896). j5. winteri var. b, PFR., Monogr. iv, p. 382

Varies a good deal in form, color and sculpture, and occurs both 

 sinistral and dextral. 



A. HEERIANUS ('Mousson' Pfeiffer). PL 48, fig. 10 (type), figs. 



11, 12. 



Perforate, ovate-conic, rather thin, rudely striate and sculptured 

 with very fine and close spiral striae; pale tawny-whitish, densely 

 streaked with cinnamon; but slightly shining. Spire broadly conic, 

 the apex rather acute, suture superficial, somewhat hair-margined. 

 Whorls 6, a little convex, the last more swollen, a little shorter than 

 the spire, with a narrow white umbilical patch. Aperture slightly 

 oblique, somewhat rhombic-oval, white and glossy ihside; peristome 

 rather broadly expanded and narrowly recurved, white, the margins
