 Good specimens.

Stations 2, 6. 7. 36. 



Frequent and very typical at Station 6. Less typical at the other N.Z.

Cristellaria 'paucisc'pta, Reuss, 1852, SFL. p. 17, figs, a, b. 



Station 18. 



A single specimen which appears to represent Eeuss's figure. The species 

 named C. paucisepta by Seguenza (S. 1879-80, FTR. p. 141, pi. x [error for xiii], 

 fig. 13) is an entirely different form, allied to C. crassa. Reuss's paper is probably
