BOYSIDIA. 209 



Whorls 6, convex, the last strongly ascending in front. Aper- 

 ture inclined a little backward, obliquely subcordiform, peri- 

 stome continuous, appressed above, rather well expanded, 

 brown-lipped, the outer margin sinuous, provided wth a tooth- 

 like callous above. Parietal lamellae three, the right one low, 

 attaining the margin, the middle one shorter, strongly ele- 

 vated, he third one short, tooth-like ; columellar lamella strong, 

 horizontal; palatals 4, of which the median 2 are stronger, 

 opposite to the columellar and median parietal, in form of a 

 cross. Diam. 2.33, alt. 3 mm. (Mlldff.).

By its long, parallel angular and parietal lamellae (fig. 7) 

 this species is related to the far smaller B. paviei. In other 

 characters it approaches B. kelantanensis somewhat. 



The entire surface is most minutely, densely granulate, with 

 only faint, sparse traces of growth-lines; it is opaque and 

 cinnamon-brown, but varying a little in shade. The aperture 

 is nearly vertical, its length diagonal to the axis. Peristome is 

 continuous, the parietal margin being thickened and raised 

 but not free, arching well up on the face of the whorl. Nine 

 or ten teeth. The angular lamella is very long, nearly parallel 

 to the stouter parietal ; infraparietal short. There are usually 

 some low wrinkles on the parietal callous (fig. 7). The colu- 

 mellar lamella is horizontal. There is a subcolumellar below 

 it. The plicae vary somewhat, but in most shells examined 

 there are rather large, subequal upper and lower palatals, with 

 smaller basal, infrapalatal and suprapalatal plicae, the last 

 usually concealed behind the stout tubercle which terminates 

 the lip-callous, at the upper third of the outer lip. The teeth 

 are granulose but not spiniferous. Alt. 3, diam. 2.25 mm. 



It may be convenient to mention that specimens of this 

 species have been received here, and doubtless by other 

 museums, under the names Boysidia moellendorffi Bttg., B. 

 javana Mlldff. and B. boettgeri Mlldff., all for exactly the 

 same form. Only the last name has been published. Part of 

 those seen (and probably all) were collected by Fruhstorfer.
