don plebeius) is a brown or slate-coloured shell half an inch in 
length. The interior is reddish-purple, with six or eight narrow 
darker lines on the whorl.

pale brown or white shell, under half an inch in length, and found 
all over New Zealand. 
MARINULA FILHOLI (Plate VII.).—Fig. 25 is a pale 
chestnut-coloured shell, with two large and one small white plaits

delus costellaris) is a brown, horny-looking shell, over half an inch 
long. It has two plaits on the inner lip. It is found in Auckland
