 Stat. ? 4 Spec. 



This fine species is somewhat variable in its markings. The ziczac lines are more or less 

 strong and the dots indicating two bands are often wanting, with several intergrading patterns. 



4. Alarginclla abyssicola n. sp. PI. XVIII, fig. 8. 



Stat. 2ii. 5°4o'.7 S., I20°45'.5 E. Banda Sea. 1158 M. Coarse grey mud. 1 Spec. 



Shell small, volutiform, white, thin, pellucid, smooth and very shining. Spire short, conical, 

 with very obtuse apex; whorls about 4, slightly convex, with an indistinct suture, filled by 

 enamel, shortly ascending near the aperture; last whorl convex, especially at the shoulder. 

 roundedly triangular in the dorsal view. Aperture elongate, rather wide, its margin slightly 

 expanded and thickened by a porcellaneous rim, angular above in the front view, arched in 

 the lateral view; interior smooth. Columellar margin with 4 thin plicae, which are oblique, 

 especially that bordering the conspicuous but not large basal sinus. 



Alt. 5 1 /,, lat. 3; apert. alt. 4, lat. 7 / 8 Mm - 



Allied to AI. lacvigata Braz. (Proc. Lin. Soc. N. S. W. 1877. p. 225) figured by Hedley 

 (Australian Mus. Vol. IV, 1901, PI. 16, fig. 5) which should be, according to the lastnamed 

 author, the same as M. valida Wats. (Chall. Report. Zool. XV, 1886, p. 267, PI. 16, fig. 3). 

 If the new species does not differ only on account of youth, it may be at once distinguished 

 by its smooth peristome-, the columellar teeth, as figured by Hedley are more developed, his 

 figure is broader, etc.

Stat. 2. Madura-strait. 56 M. Grey mud with some radiolariae. 1 Spec. 

 Stat. 7. Near reef of Batjulmati (Java). 15 M. Coral and stones. 2 Spec. 



The specimens are very small, though two of them are fullgrown with strongly developed 

 margin of the aperture, the largest from Stat. 2 being only 1 3 1 / 4 Mill. in length, that from 

 Stat. 7 scarcely 13 Mill.; in this latter specimen, the top is umbilicated, whereas in the young 

 specimen accompanying it, a thin layer of enamel closes the spire.
