LIMICOLARIA, EAST AFRICA. 295 



L. acuminata MARTS., Nbl., 1895, p. 183 ; Beschalte Weich- 

 thiere, p. 113, pi. 5, f. 4. 



The markings resemble L. martensiana multifida, but the 

 upper whorls are almost flat in profile, making the upper 

 part of the shell more slender, more regularly conic than in 

 any related species. The type is probably young. 



67. L. VENTRICOSA Smith. PI. 32, fig. 20. 



Shell pyramidal, obtuse at the apex, imperf orate; pale 

 flesh-colored, with black or deep brown stripes, more or less 

 wavy; sculptured with delicate growth-lines and a few spiral 

 striae. Spire very obtuse at the apex. Whorls 7, very con- 

 vex, slightly impressed and concave below the oblique sutures 

 in the last two whorls; last whorl short, subglobose. Aper- 

 ture reversed ear-shaped, wide, dark inside, about three- 

 sevenths the total length ; peristome thin, the right margin 

 arcuate, columellar margin a little straightened, reflexed, 

 purple. Length 44, diam. 22, apert. 18x11.5 mm. (8m.}.

' ' Remarkable for the convexity of the whorls, the obtuse 

 apex, and color. The stripes on the upper whorls are rich 

 brown, but upon the body whorl they become almost black. 

 They are wavy and narrow on the upper half of the whorls, 

 but widen out into broad blotches on the lower part " (Smith) . 



68. L. TURRIFORMIS Martens. PL 33, fig. 30. 



Turrite, rather thin, closely and somewhat granulose- 

 striate, with sparse, indistinct impressed spiral lines; pale 

 straw-yellow, with pale reddish vertical or weakly zigzag 

 streaks. Apex rather obtuse. Whorls 10, slightly convex, 

 somewhat plicate at the suture, the last whorl gradually 

 tapering below. Aperture obliquely trapezoidal, long, two- 

 fifths the length of the shell. Outer lip thin; columellar 

 margin short, vertical or slightly oblique, very thin below, 

 running out in an angle, pale violet; interior pale bluish. 



Length 93, diam. 41; length of apert. 39, width 22 mm.
