ON AFEODONTA MKLV, AND PONS. 339 



spicuous cliaractei's : The shell (of per fid a) is larger and 

 relatively lower, though the spire is more elevated above the 

 last whorl ; the whorls are more numerous, and the folds are 

 longer and further from the peristome, giving a deceptive 

 appearance of external grooves not observ^able in trilamel- 

 laris. 



Endodonta [Endodonta (Afrodonta)] farquhari //. 

 sjj. PL XXIV, figs. 7-10. 



Shell minute, subdiscoidal with convex spire slightly raised, 

 deeply and moderately widely umbilicate, horn-coloui', thin, 

 translucent, silky ; whorls 4, narrow, convex, the last rounded 

 at the pei'iphery, deeply impressed at the sutures, very closely 

 microscopically striate except the first Ih, which are smooth ; 

 aperture nearly erect, broadly crescentic, with thin peri- 

 stome slightly thickened towards the columella, and furnished' 

 with the following internal whitish lamelhv or folds : (a) One 

 near the base of the columella, strong, thick, tooth-like, 

 pointed above, set slightly back from the peristome and 

 running inwards only a short way; (b) three on the outer 

 wall, one about the periphery and the other two at nearly 

 equal distances between it and the columellar fold, the lowest 

 being set back from the peristome a little further than the 

 columellar, the second a little further than the lowest, and 

 the uppermost a little further than the second, and each 

 being about "4 mm. long, fairly strong-, and well defined; 

 (c) two on the parietal wall, one a little above and the other 

 a little below the middle, both long and strong, specially the 

 lower, and extending from the indistinct callus, just outside 

 of the aperture, inwards till lost sight of in the interior of the 

 shell.
