50 C^ECILIOIDES, GLESSULA. 



Geostilbia philippinica Mlldff., Bericht Senck. Nat. (Jes. 

 1890, p. 248, pi. 8, f. 8. 



Described from one example. The figures, drawn by Dr. 

 Boettger, show a distinctly truncate columella. This char- 

 acter and the broad sutural margin seem to differ from the 

 following species. 



49. C. MOELLENDORFFI n. sp. PI. 15, figs. 4, 5. 



The shell is clear corneous, glossy, marked with faint 

 growth-lines and under a high power some faint traces of 

 spiral striation are visible in places. The spire tapers regu- 

 larly to the obtuse summit. Slightly over 4 whorls, convex 

 and rapidly enlarging. Suture narrowly margined. The 

 aperture is ovate; columella straightened below, not in the 

 least truncate and not calloused. The outer lip is strongly 

 arched forward. Length 4, diam. 1.4, length aperture 

 1.55 mm. 



Philippines: Mananga, Zebu (Quadras coll.) 

 The spire tapers much more than in C. gundlachi, the last 

 whorl being wider, and the aperture is larger. The sutural 

 margin is narrower than in C. gundlachi. In the type lot 

 the columella is not calloused. C. philippinensis is a larger 

 shell with proportionally smaller aperture. I have not been 

 able to compare specimens of C. mariei and C. balanm.

The shell is imperforate ovate-conic or turrite, brown or 

 corneous-brown, glossy and usually without strong sculpture; 

 apex obtuse. Aperture irregularly oval; outer lip unexpanded, 

 acute or blunt; columella short, more or less deeply concave, 

 abruptly truncate at the base. 



Sole without distinct median area; no pedal margin; an outer 

 mantle lobe on the left side. Kidney very long, band-like.
