Bullia digitalis^ one of the Nassidae, is found abundantly on the 

 shores of Muizenberg in False Bay. Like certain species of the Nati- 

 cidae and some Lamellibranchs, it is possessed of an aquiferous system. 

 This Gastropod has a large flat foot, and when it is picked up or tou- 

 ched the foot is retracted into the shell, and at the same time jets of 

 water are shot out from the foot. Some forms however will not eject 

 the water even when considerably irritated. The water issues with 

 considerable force and may be ejected to a distance of three or four 

 feet. There are four such jets of water, and the pores are situated close 

 to the pedal tentacles. Two of these tentacles are placed anteriorly, 

 one on each side, at the lateral margin of the broad foot. They are 

 about V4" in length, and project outwards and backwards. The other
