A few specimens from Station 6, differing from the Kerimba specimens, upon 

 which the species was, in part, originally diagnosed, in the greater proportion of 

 sponge-spicules employed in the construction of the test.

Stations 2, 3, 6, 29, 31, 32, 40, 54, 55. 



Extends over the whole area, the best at Station 6 (N.Z.), and in the 

 Antarctic at Stations 29 and 32. At both these Stations the specimens are 

 sessile upon sponge-spicules, roimd which the chambers have coiled themselves. 

 At Station 55 specimens are free and wild-growing.

Placopsilina Jcingsleyi, Siddall, 1886, LMBC. p. 54, pi. i, tig. 1. 



Station 48. 



At this Station a specimen, attached to a Polyzoon, and constructed of fine 

 mud, spicules, and diatoms, resembles very closely SiddaU's figure. Beyond this 

 we are not prepared to go, as the type specimen is not to be found among the 

 Siddall collection, which is in our possession, the specimen being absent from his 

 type-slide.
