Limicolaria Donaldsoni n. sp. 



Shell narrowly perforate, oblong-ovate, rather thin. Spire ter- 

 minating in a very obtuse rounded apex. Whorls slightly over 6, 

 quite convex, separated by deep sutures. Surface shining, finely 

 striated longitudinally, the stria? cut into oblong granules by decus- 

 sating spiral impressed lines, which become subobsolete on the last 

 whorl except below the suture where they persist, although weaker. 

 Aperture ovate, a little less than half the length of the shell, bluish- 

 white within ; outer lip thin and sharp ; columella straight in the 

 middle and above, slightly concave below, the columellar lip re- 

 flexed over the umbilicus. Color white under a very thin yellow 

 cuticle, with faint narrow, sinuous and interrupted brown streaks. 

 Alt. 39, diam. 20£ mm. ; alt. of aperture 17, width of cavity in the 

 middle 10 mm. 



The Haud (Dr. A. Donaldson Smith, July 25, 1894). 



Type is No. 68,114, coll. Acad. Nat. Sci. Phila. Of described 

 species, L. Beccarii Morel, seems to be nearest to this one ; but that 

 has the spire longer and less obtuse at apex, a stronger color-pattern, 

 etc. L. Donaldsoni is remarkable for the unusual convexity of the 

 whorls. None of the very numerous species described during the 

 last few years seem near to this form. 



Limicolaria Vanattai n. sj>. 



Shell very narrowly perforate, oblong-conic, compact, thin, white 

 under a thin yellow cuticle, variegated with many longitudinal, 

 almost straight, streaks of rich chestnut, rather close and narrow, 

 but with a few broad ones among them, the latter often wedge- 

 shaped, wider below ; the streaks neither branching nor zig-zag. 

 On the last whorl the longitudinal markings are to a great extent 

 coalescent or smeared together below the periphery, the darker 

 color predominating on the base. Sculpture : close and fine 

 costuhe cut into oblong granules by spiral impressed lines ; the 

 decussation fine and regular on the spire; but below, the spirals be- 

 come less regular and disappear on the latter part of the body 

 whorl and are wanting on the base, and the costulse on the last 

 whorl are coarser. Spire rather thick, conic, the apex very obtuse, 

 rounded ; suture moderately impressed, margined below by a light 

 line. Whorls 7 2, slightly convex, the last slightly attenuated be- 

 low. Aperture narrowly ovate, livid within, its height contained 

 2k times in alt. of shell; acuminate above. Columella cylindric, of 

 a purple-flesh color, distinctly convex in the middle, bending toward
