602 MR. E. A. SMITH ON SHELLS [JunC 2, 



Aperture elongate-pyriform, acute above, effuse at the base. Outer 

 lip thin, sharp, arcuate, and prominent at the middle. Columellar 

 margin rather thickly covered with callus, united above to the outer 

 lip. Length of two specimens, consisting of five whorls, 30 and 25 

 millim.; diameter 11 and 10|; aperture 14 and 12 long, 6 and 5 

 wide. 



Hah. " Imbedded in a dark calcareous loam exposed in the banks 

 of a large stream at Sulagina, north coast of San Christoval" 

 {Guppy). 



This species has a good deal the form of M. queenslandica. Smith, 

 but has a more turreted spire, colour-markings, and more distinct 

 spiral sculpture. 



45. Melania uGiENSis. (Plate XXXVII. fig. 4.) 



Shell subulate, acuminate, beneath the epidermis (which is wanting 

 in the specimens at hand), of a dirty pale livid or purplish tint. 

 Whorls probably about 14 in number ; the eleven remaining are a 

 little convex, rather slowly enlarging, and sculptured with close-set 

 obliquish fine riblets which are crossed by crowded spiral strise. 

 Last whorl large, with the riblets rather obsolete below the middle, 

 and very close together, much more numerous than those upon the 

 upper whorls. Aperture obliquely pear-shaped. Length 25 millim., 

 diameter 8 ; aperture 8g long, 4i wide. 



Hab. From a stream in Ugi. 



Of this species only three dead specimens were obtained. They 

 were all completely covered with a hard thickish coating of lime, so 

 that no part of the sculpture was visible. This earthy covering was 

 easily chipped off, and the ornamentation was revealed in most perfect 

 condition. It is remarkable that the fine close riblets exist not only 

 on the upper whorls but continue to the last, and are cut across by 

 the spiral striae, producing an almost granular aspect. 



46. Melania sanct^ ann^. (Plate XXXVII. figs. 5, 5 a.) 



Shell small, acuminately pyramidal, somewhat eroded towards the 

 apex, covered with a yellowish-olive epidermis, and sometimes marked 

 with a few indistinct reddish irregular spots and lines near the middle 

 of the body-whorl. Whorls 5-6 remaining, flattish at the sides, 

 divided by a slightly oblique distinct suture, all with the exception 

 of the last one or two more or less distinctly longitudinally finely 

 plicate ; the plicae are more conspicuous in some specimens than in 

 others, being at times entirely eroded. The other sculpture consists 

 of fine lines of growth and a few rather distant spiral striae, which 

 cut across the incremental lines and produce a puckered appearance. 

 Aperture elongate, pyriform, pale bluish within. Length of 

 specimen consisting of six whorls 13 millim., diameter 5 ; aperture 

 5 long and 2| wide. 



Hab. " From a stream in the interior of Santa Anna" (Guppy). 



This is a small species, somewhat like M. boninensis of Lea in 

 form, but differently sculptured.
