LIMICOLARIA. 297 



Tinexpanded, acute; columella reflexed; outer margin slightly 

 arched forward; no parietal callous. Length 32, diam. 11%, 

 aperture 1114x6 mm. (Bgt.). 



Ubuari (Oubouari or Ubwari) peninsula, on the west side 

 of Lake Tanganyika. 



L. lamellosa BGT., Moll, de TAfric. equat., pp. 104, 108, 

 pi. 6, f. 2 (1885). 



This little Limicolaria is very remarkable by its coloration 

 of a very pale yellow and by the shell elegantly grooved by 

 regular lamellae, equidistant, and very strongly pronounced. 

 Possibly it may belong to the Buliminoid series. 



70. L. SCULPTURATA Ancey. 



Shell ovate-fusiform, thin, perforate, greenish-corneous, 

 obliquely sculptured with fine and close strise. Spire oval- 

 attenuate, rather obtuse, the apex smooth. Whorls 7, a little 

 convex, parted by an impressed suture, regularly increasing, 

 the last oval, tapering at the base, the striae gradually dis- 

 appearing below the middle. Aperture oblong, a little lunate, 

 angular above, attenuate posteriorly, slightly oblique; peri- 

 stome acute, thin, the outer margin elliptical, basal margin 

 short, forming an obtuse angle with the straight columellar 

 margin, which is widely expanded, covering the umbilicus 

 above, tapering below. Length 18, diam. 7.5; aperture 7.5 

 mm. long. 



Mozambique (Ancey). 



L. sculpturata ANC., Bull. Soc. Malac. Fr., vii, p. 346 

 (1890). 



According to Ancey, this pretty unicolored species may 

 be compared to L. lamellosa, but its general appearance is

 of grain from the northern part of Mozambique. 



71. L. HIDALGOI Crosse. PI. 30, fig. 16. 



Shell nearly-covered umbilicate, globose-turrite, ventricose, 

 thin, striatulate, very obsoletely decussate, somewhat shining, 

 diaphanous, pale olivaceous-buff, uniform. Spire moderately 

 long, the apex obtuse; suture simple, irregular, slightly sub-
