Ocean (Nicobars, Ceylon, Malay Archipelago) (Moll. Mauritius, p. 301), says: "Es ist mir nicht 

 moglich, west- and ostindische Exemplare bestimmt zu unterscheiden". The Siboga-specimens, 

 in accordance with this view, are more like dolabrata, the name mainly taken for the West 

 Indian specimens, than like terebelhcm.

The specimens are very young. Many authors quote Guerin as the author of this species. 

 As I was not able to settle the question, I followed the recent opinion of Dall and Bartsch 

 (Synopsis of the Genera etc. of the Fam. Pj^ramidellidae, in Proc. Biol. Soc. Washington Vol. 

 XVII, p. 4), who quote however only the name of Ouoy.

The quoted localities I find, are: Albrochos Island, North Australia (Adams, Reeve, 

 Clessin, 1. c). New Caledonia (Tryon, 1. c), Lifu (Melvill and Standen, Cat. Hadf Coll. of 

 shells from Lifu and Uvea, Journ. Conch. 1895, p. 122), Funafuti (Hedley, Mem. Austr. Mus. 

 Vol. Ill, 1899, p. 412), Queensland (Hedley, Proc. Lin. Soc. New South Wales, 1907, Vol. 

 32, p. 482); though these localities are all Australian, it is not strange to find the species also 

 near Sumbawa, in the Southern part of the Malay Archipelago.
