Typical popelairianus Nyst. PI. 1, fig. 1. 



Last whorl dark red-brown, without malleation. Aperture 

 slightly over half the shell's length, without tubercle on parietal 

 wall. See above for localities. 



Var. thammianus Martens. PL 9, fig. 49 ; pi. 8, figs. 42, 43. 



Last whorl dark yellowish-brown, with numerous malleations ; a 

 light yellow band at suture ; cuticle lost in spots or streaks, rarely 

 zigzags. Aperture half the shell's length, with a callous tubercle 

 above on parietal wall. Lip yellow-edged. 



Length 147, diam. 89 ; apert. long 76, width 57 outside, 44 inside 

 peristome. 



Length 126, diam. 73 ; apert. long 68, width 50 outside, 36i inside 

 peristome. 



Chancamayo, in the Amazon drainage of Peru (Thamm) ; Upper 

 Magdalena valley in New Granda, and at Huallaga (Dohrn coll.) ; 

 Marmato, New Granada (Bland, in coll. A. N. S.) ; Nanegal, in the 

 wooded region of the western Cordillera of Quito 1000-2000 meters, 

 and St. Ines, on the Rio Pastaca, 1244 meters alt., Ecuador (Stiibel) 



Bulimus garcia-moreni Miller, Mai. Bl. xxvi, 1878, p. 172, and 

 (n. F.) i, 1879, p. 118, pi. 4, f. la, b, is undoubtedly a synonym, as 

 von Martens has already maintained (Conchol. Mittheil. i, p. 157). 

 The original figure of shell and egg are copied on my pi. 8, figs. 42, 

 43. It is common on the rivers of the Province Esmeraldas, accord- 

 ing to Wolf. " It seems to occur throughout entire western Ecuador, 

 up to 3000 feet, alt., and is an esteemed edible, like Helix pomatia in 

 Europe." 



Var. dohrnianus Martens. PI. 3, fig. 10. 



A specimen in Dohrn's collection is conspicuously compressed 

 dorso-ventrally ; cuticle lost in broad spirals ; mouth somewhat 

 longer, parietal wall proportionally steeper sloping, without tubercle. 

 Length 145, diam. 95 ; aperture 83 long, 58 broad measured outside, 

 44 inside peristome. Upper whorls much eroded, but showing in 

 the better preserved places the close riblets of this species. Locality 

 unknown. 



Var. connectens Martens. PL 2, fig. 1. 



Suture less deep ; parietal wall steeper, peristome thicker ; ap- 

 proaching B. valentiennesi, but showing the close riblets on earlier
