Troschel (Das Gebiss der Schnecken, II, p. 221, PL 21, fig. 7) has described and figured 

 with some doubt, the radula of this species, of which he had received the soft parts without 

 the shell, from G. Nevill, and though he has recognized, that its place is not in the group 

 Umboniinae^ he still left it in that company. He says that the radula more resembles that of 

 Gibbula. Pilsbry (I.e.) says: "the radula has teeth considerably like Monodonta and Diloma, 

 but still locates the genus in the Umboniinae. The radula of a specimen from Banda, examined 

 by me, agrees with Troschel's figure and description, and thus no doubt about the correctness 

 being left, I think the genus may be removed from that group. As Pilsbry (1. c. p. 6) places 

 the species without a jaw in the subfamily Trochininae, those with a jaw in the Gibbitlinae^ 

 and neither Troschel nor I have observed a jaw, it should be provisionally located in the 

 subfamily Trochininae.

Though the specimens from the mentioned localities, differ in some respects from the 

 description, I think this may depend upon their juvenile state, the largest specimen having only 

 an altitude of 9 Mill, instead of 13, and 9 whorls instead of 12, with 11 lirae against 15 — 16 in 

 the original description, 15 — 18 in Journ. Conch. 1879. As however the specimens vary in this 

 respect, and the other characters agree, I think it unnecessary to give them even a new varietal 

 name. The colour is slightly variable, being more or less painted with white. The top-whorls 

 are in a few specimens painted with coral-red.
