a circular form and is inclined to be bluntly carinate. Three only 

 occur, Locality : Uncertain. 



PI. 17, fig. 13 is circular in section and is probably a variation 

 of the trifacial form, which generally has the sides more or less 

 flattened. Four occur, one of which is much more globular 

 than the one selected for illustration. Locality: Nos. 1, 3, 18, 29. 



PI. 17, fig. 14. This appears to be L. lucida in a spinous con- 

 dition, rather than L. staphyllearia in a lucida condition. Only 

 one found. Locality: No. 29. 



There is also another very similar to the above, in which the 

 lower half of the keel splits and becomes triple. The central 

 one is serrated. Locality : No. 23. 



Lagena multicosta Karrer sp. 



Fissu7'ina multicosta Karrer, 1877, p. 379, pi. 166, fig. 20. 

 Fisstirina boitei, Ibid. p. 378, pi. 166, fig. 19. 



There are a few very small examples of this species and they 

 are mixed up with Z. costata on the slide, so that the exact 

 localities cannot be given. 



Lagena fasciata Egger sp. (PL 17, fig. 15). 

 Oolina Jasciata Egger, 1857, p. 270, pi. 5, figs. 12-15. 



The type form is very rare. 



Pi. 17, fig. 15. This is the L. anyiectens Burrows and Holland,, 

 1895, p. 203, pi. 7, fig. 11. It is very small, beautifully trans- 

 parent, and the tube is short and straight. The examples vary 

 in form from globular to moderately compressed. Very numer- 

 ous. I^ocality : They were nearly all found at Nos. 8, 9, 11. 



Lagena fasciata Egger sp. var. nov. spinosa (PI. 17, 



figs. 16, 17). 



There are a good number of this interesting form. In the 

 larger examples the curved bands are generally distinctly raised. 

 Sometimes, especially in the smaller ones, the curved bands are 

 little more than fine, opaque lines. The basal spines are well 

 developed. The aperture is long, curved and almost closed, and 

 I think is composed of a series of fine pores. The entosolenian 

 tube varies in length, but is always straight. The edge of the 

 test is sometimes flattened. These specimens might, with equal
