Stat. 59. Western entrance of Samau-strait. 390 M. Coarse coralsand with small stones. 2 Spec. 



Stat. 98. 6°9'N., i20°2l'E. Sulu-archipelago. 350 M. Sand. 1 Spec. 



Stat. 256. 5°2Ó'.6S., I32°32'.5E. Near Kei-islands. 397 M. Greyish green mud. 3 Spec. 



The specimens seem to be more or less faded, though one from Stat. 59 contains the 

 soft parts. I suppose Tryon is right when he writes (1. c. p. 71) dealing with O. pulchella Duclos : 

 Weinkauff considers it {pulchella) identical with O. leucosonias Gray, with which it appears to 

 me to have but little in coramon. 



2. Olivella sp. 



Stat. 95. 5°43'.S N., ii9°4o'E. Sulu-archipelago. 522 M. Stony bottom. 1 Spec. 



A bleached and broken shell, which is much thicker than the preceding species, could 

 not be identified, being in too bad condition.

 Dead coral, Halimeda, Lithothamnion. 1 Spec. 



If one has only young specimens at hand, as is the case with the 3 Siboga-specimens, 

 one can conceive that Sowerby made at new species A. cylindrica of them, but after comparison 

 I can agree with the authors who consider them as young ones of A. ampla. The Siboga- 

 specimens have no: "red-stained spire", as the type, according to Reeve's statement (1. c. fig. 46), 

 should possess, but this is in my opinion a very insignificant difference.

Stat. 51. Madura-bay. 69 — 91 M. Fine grey sand, coarse sand with shells and stones. 1 Spec. 



I think this species will be more nearly allied to the preceding one than to A. mauritiana, 

 of which species it should be, according to Tryon, a miniature shell. In this latter species the
