Red Challc Foraminifera. By Burrows, Sherborn, and Bailey . 551 
supplied by Mr. J. T. Day, F.G.S., who also suggested the method 
of disintegrating the hard material which is described in the 
footnote.* 
Many of the specimens obtained are gigantic in comparison with 
those from the same and other localities. 
(3) A still larger collection of balsam-mounted slides of material 
from Speeton, disintegrated and prepared by the Rev. G. Bailey. The 
greater part of this material was obtained from a deep-red band 
about two miles east of Speeton Gap, and near the boundary line of 
Buckton and Bempton parishes. It was collected at extreme low 
water during spring tides, at which time the bed is most conveniently 
exposed. 
(4) A large collection of sliced Red Gaults and Red Chalks from 
various localities in Norfolk, Yorkshire, and Lincolnshire, kindly 
placed at our disposal by Mr. W. Hill, jun., F.G.S. 
(5) Three slides of balsam-mounted dust from the Red Chalk of 
Flamborough Headf lent to us by Dr. H. B. Brady, F.R.S. 
(6) A slide of dust, also balsam-mounted, by the favour of 
Dr. Clifton Sorby, F.R.S. 
We have also availed ourselves of the published records of the 
Rev. T. Wiltshire, Messrs. Parker, Jones, Blake, and Whitaker, details 
of which will be found in our previous note. 
Spiroloculina d’Orbigny, 1826. 
Spiroloculina papyracea sp. n., plate VIII. fig. 1. — The lower half 
of a thin and much compressed form from the red chalk of Flamborough 
Head. The nearest figures to this which have come under our notice 
are Spirolocidina sp. (Hantken, Mitth. Jahrb. k. ung. Geol. Anst., iv. 
1875, plate xiii. fig. 1) and 8. Freyeri (Reuss, Denkschr. k. Ak. 
Wiss. Wien, xxiii. 1864, plate i. fig. 3), of which the former shows 
rounded chambers, and the latter is referable to 8. planulata d’Orb. 
We have therefore ventured to record it under a new specific name. 
Dr. Brady’s Coll. 
S. tenuis (Czjz.) plate VIII. fig. 2. Quinquelocidina tenuis Czjzek, 
Haidinger’s Nat. Abh., ii. 1848, p. 149, plate xiii. fig. 31-34; 
8. tenuis , Brady, Rep. Challenger, ix. 1884, p. 152, plate x. fig. 9. 
One specimen (Canada balsam, Bailey Coll.) is referable to this form : 
the outer chamber has been crushed and displaced. 
* Owing to its great hardness, the separation of the Foraminifera from the Bed 
Chalk is always difficult. The following method, however, greatly simplifies the 
process : — Break up the chalk into small pea-sized fragments, and boil in strong 
solution of sulphate of soda till reduced to powder; wash till all muddiness is 
removed. 
f Speeton or Buckton. This applies also to the “ Flamborough Head ” of 
Emmett, these being the nearest places to Flamborough Head at which the red 
chalk crops out. (See Parker and Jones, ‘ Geologist/ 18G0, p. 419.)
