Trvon has pointed out the differences in sculpture and colour between this and the 

 preceding species, the brown spots below the suture are often very faint and nearly wanting 

 on the specimens from Stat. 258. At Stat. 260, near Nuhu Jaan, has been found a small, dead 

 shell, at a depth of 90 M., which may be a somewhat scalariform specimen of this species, 

 with the aperture not developed; as I am however very uncertain, I have not mentioned it 

 amongst the list of localities.

Only a few specimens perfectly agree with the figure of Reeve (1. c.) the majority is 

 considerably larger and differs more or less in sculpture and colour. Mr. Smith whom I asked 

 his opinion, declared these doubtful specimens to be colourless and partly dead specimens of 

 N. densigranata. Mr. Melvill wrote about other very aberrant specimens, that they resembled 

 in some degree his N. sturtiana (Proc. Zool. Soc. Lond. 1901, p. 413, PI. 23, fig. 14) 

 but that this species has the ribs quite smooth. Under these circumstances I have foliowed 

 Mr. Smith's advice.
