Stations 2, 3, 6, 27. 



Fine specimens in tlie N.Z. area, especially at Station 6. Fistulose at 

 Station 2. Fossils at all the N.Z. Stations. At Station 6 a large abnormal 

 individual intermediate between P. compressa and P. ovata in the arrangement of the 

 chambers. Outside the N.Z. area the record depends on a single specimen at 

 Station 27. Pearcey's P. inflata appears to be merely a pauperate form of this 

 species. P. 1914, SNA. p. 1023, pi. ii, figs. 14-16.

Stations 1, 2, 3, 5, G. 



This handsome species is the most typical N.Z. representative of the genus. 

 Specimens are abundant and attain large size, especially at Stations 2 and 6. 

 Fossils at Stations 1, 2, 3 and 6. The species does not appear to be subject to 

 fistulose variation.

 and two fairly large specimens at Station 55, farthest S.

Stations 1-3, 5, 6, 48. 



Confined to the N.Z. area excopt for one very small specimen at Station 48, 

 Common at Station 6, where fistulose examples occurred. The largest, perhaps, 

 at Station 1. Fossils at Stations 2, 3 and. 6.
