Lagena laevigata Reuss sp. var. Sidebottom, 1912, Journ. Q. M. 0. T 

 p. 400, pi. 17, fig. 7. 



+ P1. 17, fig. 7. Very rare. Locality : Nos. 15, 34. 



Lagena acuta Reuss sp. (PI. 16, fig. 7). 



Fissurina acuta Reuss, 1862, p. 340, pi. 7, fig. 90, and F. apiculata r 

 p. 339, pi. 6, fig. 85. 



Lagena acuta (including such as have only the slightest indica- 

 tion of the apiculate process) is found at almost all the localities.. 

 The size and inflation of the tests, as well as their outlines, vary 

 greatly. Two at No. 14. 



Lagena acuta Reuss sp. var. (PI. 16, fig. 8). 



The chief feature of this variety is the curious oval marking at- 

 the base, on both sides of the test. It is very rarely so clearly- 

 shown as in the drawing. The tests are opaque or nearly so, and 

 when the shell-substance becomes very dense the markings 

 disappear, but if damped some trace of them can be detected. 

 Locality : Nos. 3-7, 9-11, 13 15, 29, 33, 34, 39, 40, 42, 44. 



+ P1. 17, fig. 9. The mixing of this form w T ith that of fig. 10' 

 prevents me from giving the exact localities, but it is evidently 

 rather rare. They correspond with the Fissurina apiculata Reuss,.

+ P1. 17, tig. 10. This appears to occur at nearly all the 

 stations up to No. 22, after which it is extremely rare.
