Reeve's hg. 59 (margaritifera) seems to be scarcely the same as Dunker's species. 

 The fio-ure of Pilippi is more reddish-brown banded than any specimen I have seen (may it be 

 bleached?) but the description agrees in every respect, only I find the number of granules on 

 the columellar side more variable.

 Stat. 277. Kulewatti-bay, Dammer-island. 45 M. Sand, white and black mixed. 1 Spec. 



I at first thought the species might be new, but Mr. Melvill had the kindness to point 

 out the identity with his N. angriasensis, adding that his figure was rather faulty, the description 

 agrees rather well, but the Siboga-specimens have additional brown markings between the bands 

 of last vvhorl, not mentioned in the original description.

Stat. 204. Between islands of Wowoni and Buton. 75 — 94 M. Sand with dead shells. 1 Spec. 



The specimen is larger than Lamarck's type, measuring an inch in length instead of 

 10 lines.

Stat. 313. East of Dangar Besar, Saleh-bay. Up to 36 M. Sand, coral and mud. 4 Spec. 



Differing only from the typical gemmulata in size, though it is often more coloured, I 

 have seen specimens which agree in colour with the type, which is likewise not always constant 

 in this respect.
