292 FORAMINIPERA OF THE CRAG. 



Gharaders. — Shell troclioidal, upper face conical, lower face nearly flat ; many 

 chambers visible in the spire, five to nine shown below. 



Occurrence. — This species, which is the type of the genus, is rather rare in the 

 recent condition. The ' Challenger' obtained specimens off Capede Verde Islands 

 (11 fathoms), off Ascension (420 fathoms), near Pernarabuco (350 fathoms), and 

 at Port Jackson (2 to 10 fathoms). Brady also records specimens from the coral 

 sands of Bermuda, and from Port Stephens, New South Wales. The ' Gazelle ' 

 obtained specimens from one station only, off Mauritius (223 fathoms). 



The fossil records are from the Chalk of Maestricht ; the Neocomian (Bargate 

 Beds of Surrey) ; the Eocene (Calcaire Grossier) ; the Miocene of Calabria and of 

 Muddy Creek (Victoria) ; and the Pliocene of St. Erth.^ In the Coralline Crag 

 we have specimens from Tattingstone and Broom Hill, zone d, from Satton, 

 zones c and f, and from Gedgrave, zone f.

1 The St. Erth specimens of D. turbo are similar to D. solarium of Seguenza. The specimen from 

 the Crag here figured seems nearer to D. rosacea. — P. W. M.
