592. Pulvinulma harsteni (Reuss). 



Eotalia harsteni, Reuss, 1855, KKM. p. 273, pi. i-\, fig. 6. 



Pulvinulina karsteni, Brady, 1864, RFS. p. 470, pi. xlviii, fig. 15 (after Reuss) ; 1884, FC. p. 698, 

 pi. cv, figs. 8, 9. 

 „ Herou-Allen and Earland, 1916, FWS. p. 276, pi. .xlii, fig.s. 34-37. 



Stations 1-6, 11, 16, 18, 19, 23, 36 ( + T. d. F.). 



Strong, thick-walled individuals of the Reuss-Brady type. Common. The 

 only noteworthy point is the occurrence of typical individuals at the shallow 

 water N.Z. Stations, though there are records in lesser depths. {See note to 

 P. exigua.) 



593. Pulvinulina elegans (d'Orbigny). 



Rotalia (Turbimdiua) decjans, d'Orbigny, 1826, TMC. p. 276, no. 51. 

 Pulvinulina elet/ans, Heron-Allen and Earland, 1914, etc., FKA. 1915, p. 717. 



Stations 1-3, 6-8, 10, 11, 23, 36 (+ T. d. F., R. d. J.). 



Frequent, and well developed at most of the N.Z. Stations, especially Stations 

 1, 2 and 6. Most of the specimens are of a hyaline texture, even when the walls 

 are thick. Pauperate, thin-walled, compressed specimens at Stations 2 and 3. 

 A thick-walled deep-water specimen at Station 7. At Station 10 a considerable 

 number of very small and very thin-Avalled individuals. A specimen sessile on a 

 Hydroid stem at Station 2. 



594. Pulvinulina partscJiiana (d"Orl)igny). 



Rotalina partschiana, d'Orbigny, 1846, FFV. p. 153, pi. vii, figs. 28-30, pi. viii, figs. 1-3. 

 Pulvinulina paiischinna, Heron-Allen and Earland, 1914, etc., FKA. 1915, p. 717; pi. liii, 



figs. 12-14. 



Stations 6, 7, 10, 11, 12, 14, 36. 



This species is l)iologically inseparable from P. elegans. The name has been 

 reserved for the very thick benthic forms of that species. Such individuals occur, 

 typical and well-developed, at Station 7, an interesting series of specimens 

 showing the decomposition of the shell-wall by the separation of the laminae 

 of which it is composed. Similar specimens at Station 11, but less advanced in 

 lamination. A monstrous or double individual at Station 36. 



595. Pulvinulina herthelotiana (d'Orbigny). 



Rotalina berthelotiana, d'Orbigny, 1839, FIC. p. 130, pi. i, figs. 31-33. 

 Pulvinulina „ Brady, 1884, FC. p. 701, pi. cvi, figs. 1 a-c. 



de Amicis, 1893, CFP. p. 455, pi. iii, figs. 12, a-c. 



Stations 1 and 2. 



Fine and large specimens. Some very limbate, others almost smooth.
