This shell, although without a locality attached, iu all 

 j)robabilitj iiiiiabits the Ca[)c of Good Hope, having with 

 some species from there such a general resemblance as to 

 warrant the supposition ; the brown band occupies about half 

 the whorls, not quite reaching the upper ends of the ribs.

The two apical whorls are remarkably large. The faint 

 nodules at the top of the whorls and the more distinct ones 

 around the middle have faint dots of brown between them ; 

 and the spiral striae are interrupted by them.

[Plate XX.] 



It will, I tjiink, be conceded that a special degree of interest 

 attaches to the Foramiuifer about to be described, when I 

 state that it not only represents a vyell-marked new genus, but 

 is one of the very few forms as yet discovered whose pecu- 

 liarities of structure point to their being sessile inhabitants of 

 the bed of the ocean.
