[Plate VII.l 



In the first part of this essay * I noticed the sph^eridia and 

 pcdicellarige of a specimen of a recent Salenia which I consi- 

 dered to be probably referable to the species described by A. 

 Agassiz, and named by him Salenia varispina ; and now I 

 proceed to the com]:)arison of the other structures of the test in 

 the recent forms. But before d(3ing so it is necessary to con- 

 sider the zoological position of the specimens. 



The specimen just noticed, and which has its spines and 

 buccal membrane intact, was covered here and there with deep- 

 sea ooze, in which were many Glohigerince, This sticky sub- 

 stance enveloped the pedicellaria;, filled up the spaces between 

 the papilla; on the apical disk, and only permitted a general 

 view of the abactinal system. Long and careful manipulation 

 at intervals has g«jt rid of sufficient ooze, so that the correct 

 structural relation between this form and that described and 

 figured by A. Agassiz can now be decided. I now find that, 

 although there are some diflferences in the nature of the 

 buccal membrane and in the numbers of the primary tubercles 

 of the two foriiis which may be accounted for by iheir being
