The specimen from Stat. 47 is adult and very well agrees with the original description 

 and fio-ure, the other one is young and though the suture is not canaliculate, I am not quite 

 certain that it should not belong to the preceding or another allied species. I have not quoted 

 Reeve's fio-. 17, as in my opinion it differs too much from Kiener's figure.

This is one of the most difficult species, 'its great variability in size, colour and sculpture 



seems to have caused much controversy as to its affinities. Most authors agree in this point, 



but not respecting its synonymy. I have foliowed the views of Boog Watson (Challenger 



report) and some subsequent authors. If one compares the large forms with few ribs, with the 



smaller many-ribbed specimens, one should incline to admit more than one species, but inter- 



mediate specimens make it impossible to tracé the limit. The allies are a. o. N. taenia, canahatlata 



and siqitijorcnsis.

The specimens are not typical, they are considerably smaller, not exceeding 14 Mill. in 



length; the sculpture is slightly different from more typical specimens in my private collection,
