and very fine spiral striae, lower part of whorls with strong rounded ribs, lo on last whorl, 

 crossed by from 3 to 4 spiral lirae on lower whorls, 19 on last one, of which the upper 6 are 

 more remote, the lower ones on base and canal crowded, on the ribs the upper lirae are 

 beadlike, then the ribs disappear. Aperture narrowly elongated, peristome broken, upper sinus 

 probably wide, columellar margin slightly concave above, with a tubercle at sinus, straight 

 below, canal wide, slightly upturned, interior of aperture white. 



Alt. 15, lat. about 4-^/3; apert. alt. 5^0, lat. about 2 Mill. 



Though this specimen is not quite complete, its shape is too peculiar to neglect it. 

 Mr. Smith who compared it for me, says it is allied to but different from angusta Smith 

 (Ann. Mag. Nat. Hist. Ser. 4, Vol. XIX, 1877, p. 495); that species is still narrower, has a 

 considerably larger number of ribs on last whorl (15) and has 5 or 6 spiral grooves on upper 

 whorls, with 5 or 6 nodules on ribs, (only 2 or 3 in the new species).

Stat. 162. Between Loslos and Buton-islands, West of Salawatti. 18 M. Coarse and fine sand 

 with clay and shells, i Spec. 



The specimen is smaller (16 Mill.) but otherwise agrees rather well with figure E i of 

 Smith and with his description of the variety.

Stat. 51. Madura-bay. 69 — 91 M. Fine grey sand, coarse sand with shells and stones, i Spec. 



This specimen, also identified by Mr. Smith, is smaller (19 Mill, instead of 25) probably 

 not full-grown, with the lirations less numerous, as it is moreover bleached, (though light yellowish- 

 brown) and not quite typical, it is unfortunately not fit for figuring this still unfigured species. 



10. Drillia rubidofusca n. sp. PL XXVI, fig. 4. 



Stat. 240. Banda. 9 — 45 M. Black sand, coral, Lithothamnion. i Spec. 



Shell fusiform, rather solid, uniformly red-brown, lighther behind peristome and at the sutural 

 sinus, and with orange base. Whorls 6, (apex broken-, the number of whorls may have been 

 at least 10) rather convex, slightly excavated below the conspicuous suture, which is accom- 

 panied by an inconspicuous infrasutural thread. Sculpture consisting of somewhat oblique ribs, 

 nearly crossing the entire whorl in the upper ones, but becoming obsolete in the infrasutural 

 depression of lower whorls, about 15 ribs on last whorl, of which the ventral ones are obsolete, 

 that behind the peristome very strong, varix-like, moreover the shell is covered with fine 

 growth-striae and very fine spiral striae, only visible under a lens, 6 spiral lirae cross the ribs, 

 in most cases with intermediate, much finer lirae and 3 to 4 very faint ones in the excavation ;
