Stat. 47. Bay of Bima, near South fort. 55 M. Mud with patches of fine coralsand. i Spec.

Stat. 260. Near North-point of Nuhu Jaan. Kei-islands. 90 M. Sand, coral and shells. i Spec. 



The specimens trom Stat. 47 and 260 have the body-whorl entirely striated, though that 

 from Stat. 260 less close than in the figures of Morlet and Pilsbry; one from Stat. 52 has 

 a smooth zone at upper part of that whorl, but otherwise I can find no important difterences; 

 the striation seems to be variable, no 2 specimens being quite equal in this respect.

Stat. 116. West of Kwandang-bay-entrance. 72 M. Fine sand with mud. i Spec. 



As this species has not been figured, as far as I am aware, I thought,it desirable to 

 give a figure of the specimen identified by Mr. Smith.

Shell large, ovate, with a rather high, conical, pointed spire, smooth, rather thin, with 

 spiral striae near the base-, whorls 6^^, rather conve.x, separated by a conspicuous, but not 

 deep suture. Nuclear whorl somewhat tumid. Sculpture consisting of very fine grovvth-striae, 

 with a few e.\ceptions only visible under a strong lens, and about 10 impressed, spiral striae 

 below the periphery of last whorl, which is ventricose and occupies at least "/s of the length 

 of shell. Aperture moderately large, with an acute angle above. Outer lip thick, strong, with 

 an e.xternal rib, regularly arcuate, nearly tooth-Iike in the middie, in quite developed specimens. 

 Inner lip thickly enamelled, forming a thickened rim at its upper part, from upper angle until the 

 conspicuous entering fold near the middie. Upper columellar fold not very strong at its exterior 

 extremitry, much more raised in the interior, separated by a deep sinus from the much .strono-er, 

 contorted lower fold, which forms at the base a deep sinus in joining the basal part of peristome.
