variation in its proportion to the horizontal one and thus distended forms sometimes 

 present themselves somewhat diverging from the flat type. Intermediate forms between 

 P. Menardii and repanda and also P. Micheliniana D'Ons. are occasionally met with. 



This species is next to Gldbigerina bulloides and universa the most common rhi- 

 zopode in deep water and attains a diameter of 1,50 mm. and more. 



The most beautiful and exact delineation of this species ever given is to be found 

 in Prof. WYWILLE TOMSONS great work The Challengcrs Exped., the Atlantic, 1, p. 

 218, fig. 48.
