471. RaniuUna {(), Text-figure. 

 Station 2. 



A single example of a very large abnormal organism, the precise nature of 

 which can only be a matter of speculation. It can best be compared with the 

 fistulose outgrowths of the racemosa type figured by Jones 

 and Chapman (J. & C. 1896-8, FPR. p. 504, figs. 17-19), 

 but it dift'ers from anything of this nature that can be 

 imagined in its enormous size. It is difficult to imagine 

 any single individual Polynwrphina extruding sufficient 

 protoplasm to form such a mass of labyrinthic tubes. 

 Many of the extensions are broken, Ymt here and there 

 nipple-like apertures may be traced on the projecting 

 tubes. Perhaps the nearest organism hitherto figured 

 with which it may lie compared is the R. yrimaldii, 

 Schlumberger (Note sur le /?. (/rimahlu, Mem. Soc. 

 ZooL, France, vol. iv, 1891, pp. 509-.51] (151-1.53 in 

 reprint), pi. v), but this abnormal form dift'ers considerably and is of a less 

 complicated structure. Our organism measures 5 by 3 mm. and has a depth 

 of 2 mm.

Universally distributed, and in the N.Z. area splendidly developed and 

 characteristic, especially at Stations 2, 3 and 6, where a large number of specimens 

 were of pelagic origin. At Stations 10, 11, 12 large benthic individuals. There is 

 a considerable range of variation in the direction of G. dubia at Station 6, and 

 of G. duterlrei at Stations 5, 6 and 7, also at Station 16, and from Station 27. 

 To the south the typical 6-'. bulloides gradually dies out and the specimens found 

 might equally be referred to G. duterlrei.
