The specimens from Lombok, are less smooth than those from Java and Celebes, but 

 agree in every other respect, with those at my disposal. I find no spines, but this may be due 

 in part, to the corrosion of 3 of the specimens. Those from Celebes, mentionecl by Gredler, 

 (Nachrichtsbl. 1902, p. 62) do not belong to this species, but to N. subpunctatd Recl., and one, 

 I think, to N brevispina Lam., as I have observed by ocular inspection, by the kindness of 

 Gredler. The largest specimen from Lombok, is slightly larger than the described types, being 

 about 15 Mill. in height and in diameter, instead of 13 and 14. Lombok is a new locality.

The specimens of var. glandiformis v. Mart. agree with those named by v. Martens 

 from Adonara, but they are smaller. From both localities the colour-markings are much less 

 conspicuous than in the type, not only by incrustation, but even in perfectly clean specimens, 

 seen by transparent light. A few of the specimens from Lombok (a new locality) have traces 

 of spines, like those from Adonara, recorded by v. Martens (1. c. p. 181).
