ANOMALINA POLYMORPHA Costa. 

 (Plate 79, fig. 3.) 



Strongly resembles A. eoronata, but is characterized by the presence 

 of one or several short,, stout spinous outgrowths, usually from the 

 periphery of the shell. If but one spine is i^resent, that is generally a 

 prolongation of the final segment. 



Locality. — Collected at the same station as A. coronata. 



Genus RUPERTIA. 



Test columnar, growing attached by a slightly-spreading base; seg- 

 ments numerous, spirally arranged; aperture at the iuner margin of 

 the final segment. 



RUPERTIA STABILIS Wallich. 

 (Plate 79, fig. 4.) 



Irregularly flask-shaped, having a moderately -inflated body, a short, 

 thick neck, and an expanded lip. The lip is formed by the spreading 

 base by which the shell adheres to some other body. The neck is 

 formed by about two superimposed convolutions; the body by the 

 inflated segments of the succeeding convolutions; walls thick and 

 coarsely i)erforated ; aperture at the inner edge of the final segment. 

 Length, 1.5 mm. {-^ inch), more or less.

Adherent; contour discoidal, more or less distorted according to the 

 form of the surface to which it was adherent; composed of numerous 

 subglobular segments irregularly heaped together, except at the very
