366 SUBANTARCTIC ISLANDS OF NEW ZEALAND. [Foraminifera. 



SUMMARY OF RESULTS. 



The dredgings on which the foregoing report is based have proved rich beyond 

 expectations, for they have yielded as many as 168 species and varieties of the 

 Foraminifera. No doubt additional species could be found by prolonged search- 

 ing amongst the finer material. 



Four new species and two new varieties are herein described, viz., — 

 Miliolina chrtjsostoma. 

 Planispirina antarctica. 



Lagena lagenoides, Williamson sp., var. nuda. 

 „ quadrafa, Will, sp., var. carinata. 

 „ enderhiensis. 

 SpiriUina novae-zealandiae. 

 Of forms new to the " Index Faunae Novae-Zealandiae " there are 103. As in 

 the Barrier Island dredgings, the present contain a few species until recently only 

 met in high northern latitudes, such as Bilocvlina vespertilio, B. pisum, and Miliolina 

 angulala. 



The most prolific genus is Lagena, with nineteen species and varieties. Of the 

 genus SpiriUina there was no record in the " Index Faunae Novae-Zealandiac " ; but 

 the present material contains as many as eight species and a variety. 



Textularia gramen is noteworthy as being amongst the commonest forms, and, 

 further, that it shows a remarkable amount of variation. 



Another most interesting species is Discorbina parisiensis, which here appears to 

 be normally in the condition of plastogamic union, the two shells being frequently 

 so well matched in size and neatly apposed as to almost pass for a biconvex test of 

 Amphistegina lessoni.
