Lagena alveolata, var. caudigera , nov. (PL LX. fig. 25). 
General conformation of the test similar to that of Lagena alveolata , but somewhat 
broader in outline ; armed at the base with two long spines springing from the median 
line ; surface near the base ornamented with faint beaded lines. 
The caudate variety of the species has only been observed in the South Pacific, south- 
west of Juan Fernandez, 1825 fathoms. 
Lagena alveolata, var. substriata, H. B. Brady (PI. LX. fig. 34). 
Lagena auriculata , var. substriata, Brady, 1881, Quart. Journ. Micr. Sci., vol. xxi., N. S., p. 61. 
General characters the same as those of Lagena alveolata ; the surface of the test 
more or less costate or striate, especially near the base and apex. 
Found at Station 146, Southern Ocean, 1375 fathoms.
