drawing. The largest specimens have the body much clogged by 

 exogenous shell-growth, or debris, through which small spines 

 often project. Locality : Nos. 17, 19. 24. 25, 35. 36. Always rare. 

 + P1. 15, fig. 5. This variation, which is much more delicate in 

 every way. is found at many stations. Locality: Xos. 1-11. 24, 

 25. 33, 35, 36. 39. 



Lagena striata d'Orbigny sp. (PL 15. fig. 17). 

 Oolina striata d'Orbigny, 1839, p. 21, pi. 5, fig. 12.

PI. 15. fig. 17. In this, the fine costae project at the base. The 

 neck is bent to one side, the body of the test is also slightly 

 curved. On a square by themselves are fifteen tests which have 

 the contour of L. clavata, with the point at which the test begins 

 to narrow towards the base sharply angular. Only two are 

 marked on the chart. Locality : Nos. 1, 3-5. 7. 8. 12. 17. 21, 24, 

 34. 39. 40. 



Lagena (Amphorina) Lyellii Seguenza sp. is found frequently. 

 This form may be treated either as L. striata, or L. sulcata in an 

 apiculate condition. 



* PI. 15. fig. 6. Twenty-three specimens are on the slide. 

 Locality : Nos. 2. 3. 4. 



* PI. 15, fig. 8. Fourteen fine examples occur, and a number 

 of smaller ones. Taking the whole series into account they pass 

 gradually into L. Lyellii Seguenza. Locality; Nos : 2-12. 15, 17. 

 21, 24, 29, 31, 33, 34. 39. 40, 42, 43. 



+ EL 15, fig. 9. Five typical tests are on the slide, but they 

 are mixed with others that are not typical, and so the exact 

 locality cannot be given with certainty. They were found, how- 

 ever, at one or two of the following stations. Locality : ZSTos. 

 1, 5, 11, 13. 



On another slide two examples are placed. Locality : 2Sos. 

 23. 24.
