THE VOYAGE OE H.M.S. CHALLENGER. 
It was found by Terquem amongst the microzoa of the Pliocene deposits of the Island 
of Rhodes.

This species also belongs to the “ auricula ” group of Pulvinulince. It is distinguished 
from the rest of the series by its less elongate contour and thick rounded peripheral 
edge. 
The Challenger collections furnish examples of Pulvinulina hauerii from seven points 
in South Pacific, the recorded depths of which vary from 17 to 620 fathoms. A single 
specimen was also taken off Palma, Canaries, 1125 fathoms. 
As a fossil it occurs in the Miocene of the Vienna Basin (d’Orbigny, Reuss), in the 
Salt-clay of Wieliczka (Reuss), and in the Upper Pliocene of the Island of Rhodes 
(Terquem). Hantken’s drawing {loc. cit .) represents a somewhat thinner shell, but 
otherwise closely resembles PI. CVI. fig. 6 ; if I am 'correct in attributing it to the present 
species, the geological range extends back to the Oligocene period.

In Parker and Jones’s arrangement of the genus, Pidvinulina menardii serves as the 
type of a considerable group of species, which includes, amongst others, all those hitherto 
found living at the surface of the ocean. 
The external characters of the typical form are well embodied in d’Orbigny’s Modele,
