This is largely represented, especially in its variations ; inter- 

 mediate forms occur which it would be interesting to figure. 



PI. 17, fig. 21. In this solitary specimen the wing has divided 

 at a point a little above the body of the shell. Locality ; No. 2& 

 or No. 39. 



PI. 17, fig. 22. A neat form which appears to be strongly

 crowned with a boss, and the loops at the base are feebly 

 represented. Nine specimens occur. Locality ; Nos. 2, 10. 



PI. 18, fig. 1. A stoutly-built form. The test is subcarinate,. 

 and the orifice situated in a depression. The two loops at the 

 base are feebly developed. Very rare. Locality ; Uncertain, but- 

 after station No. 23.

 keel being continuous round the edge of the test. Locality : Nos.

 found at Nos. 1-11. 



"*"P1. 20, fig. 13. Nine examples occur, and one is in the 

 trifacial condition. Locality ; Nos. 1, 38, 42 44 : the trifacial 

 specimen at No. 43. 



*P1. 20, fig. 14. Eight specimens found. Locality; Nos. 1-4.
