PLATE 10. cavity of the shell, twisted at the lower extremity in a hook-curve. 

 A rare instance. 



FIG. 2. Entosolenia (Quadrata). This form, with tube projecting down- 



wards internally half way, so much resembles the Actinia Crassicornis 

 of the Filliferous Capsule of the Polypii, that I refrain from entering 

 into a description of it until better known. It was not subjected to 

 a high power. A parallelogram with rounded extremities. 



FIG. 3. Lagena Vulgaris. Semistrata and punctata ; costa at the tapering 



neck only ; strise represented at base by circles of minute tubercules. 



This well-known form, with its long tubular neck and inverted 

 lip, except that the contracted portion of this was striated, while 

 the body was covered with rough tubercules, similar to some forms of 

 ForaminiferaB, of which it seems one. It curiously happened, while 



FIG. 4. examining this, a second appeared (the Nodosaria) plainly showing 



(although fractured) the course of additional chambers. In this the 

 tube was quite visible, but not the inverted lip ; the pseudopodial 

 canals and tubercules were also indistinct. 



FIG. 4. Lagena Vulgaris ( Var Perlucida). Costa not distinct ; form ovate ; 



mucro at posterior extremity. 



FIG. i. Miliolina. 



Two separate forms of Spiroloculi'iia.
