4- Drillia zotiata (Gra\) Reeve, var. 



Reeve. Conch. Ic. Vol. I, ricmotoiiia, fig. 74 (type). 



Stat. 303. Haingsisi, Saniau-islancl. Up to 36 M. Lilliothainiiion. i Spec. 



The only specimen is a )()uno-, empty shell, and without Mr. Smuh's assertion, I should 

 not have recognized it as belonging to that species. It is reddish brown, with white uj^per 

 whorls, light coloured near the base and on the ribs, but I can trace no dark zone, as figured 

 by Reeve. It is too incomplete (young) to give it a varietal name, length only 21 Mill., moreover it 

 is possible that it might have been more typical if adult. It have not quoted the figures of 

 Weinkauff or Tryon, that of Tryon being a copy of Rkf.ve's figure, Weinkauff's figure 

 agreeing no niore with the Siboga-shell ; both authors consider this species to be a synonym 

 oi D. Jlavidula. 



5. Drillia tJicoreta Melvill. 



Melvill. Ann. and Mag. Nat. Hist. Ser. 7, Vol. IV, 1899, p. 85, PI. i, fig. 2. 



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



Stat. 133. Lirung, Salibabu-island. Up to 36 M. Mud and hard sand, i Spec. 



Stat. 260. Near North point of Nuhu Jaan. Kei-islands. 90 M. Sand, coral and shells. 2 Spec. 



The specimen from Stat. 133 has the normal length of 22 Mill., one specimen from 

 Stat. 260 is very small (about 11 Mill.) the other is young, all the specimens are dead and 

 more or less bleached, but they have the maculations on the ribs. 



6. Drillia robitsta Hinds.

Reeve. Conch. Ic. Vol. I, Pleurotoma, fig. 204. 



Weinkauff. Martini-Chemn. Conch. Cab. Ed. II, Vol. IV, Pleurotoma, p. 184, 215, PI. 36,

Stat. 71. Makassar and surroundings. Up to 32 M. Mud, sand with mud, coral. 2 Spec.

Weinkauff. 



7. Drillia subangzista n. sp. PI. XXVI, fig. 3. 



Stat. 159. o°59'.iS., I29°48'.8 E. Halmahera-sea. 411 M. Coarse sand. 



Shell narrowly elongate, fusiform, very light yellowish white. Whorls 9, of which about 

 1^/2 form a slightly swollen, smooth nucleus, subsequent whorls convex, separated by an undulated 

 suture, which is accompanied by a spiral rib, conspicuous on upper whorls, becoming fainter 

 lower on, nearly disappearing towards last whorl, upper part of whorls with a rather narrow excava- 

 tion, wider but shallower on lower whorls, excavation sculptured with waved concentric striae
