 third being smaller. 



Spirillina decorata Brady. 



SpirilUna decorata Brady, 1884, Chall. Eept., p. 633, pi. Ixxxv, figs. 22-25. 



One large specimen, deeply furrowed ; the other two much 

 smaller tests might almost be taken for aS'. limhata, var. denticulata^ 

 except for the subcarination of the peripheral edge. Judged by 

 the " Challenger " figures and Brady's description none of the three 

 tests are typical, but seem to be intermediate forms between 

 S. decorata and S. limhata, var. dcnticulata.

Two occur : one is concave on both surfaces of the test, but 

 more so on the superior surface ; the other is slightly concave on 

 the inferior and convex on the superior surface.

Article xv. Report Forams., p. 354, pi. xvii, fig. 3. 



Five examples occur which are allied to Chapman's species. 

 The chief difference between my specimen and Chapman's is the 

 absence of any limbation. Chapman's figure in the 1909 paper 

 shows very little, if any, limbation of the test. The character of 

 the tubercles, or " small grulations " on the inferior surface varies 

 in different specimens. In the largest test they completely cover 

 the surface, so that the coil is hidden ; in the one chosen for illustra- 

 tion the granulation is confined to the centre of the test, the outer
