The three last have a large central chamber ; one has straight, 

 another oblique, and another curved alar divisions. 



In the ' Catal. Eoss. Forain. B. Mus.' 1882, this species is entered 

 as occurring (p. 22) at Alum Bay, in the bed " no. 29 " (on the autho- 

 rity of Mr. E. Edwards). At page 23-25 are the following : — 



Bracklesham, Barton, and Stubbington, including large, ordinary, 

 and small forms ; Emsworth (E. Edwards), probably a wrong 

 locality ; Bramshaw, ordinar}' and large (E. Edwards) ; HighclifT, 

 ordinary and large (E. Edwards). At p. 26, " a delicate variety 

 like A 7 , venosa," from Headon Hill (E. Edwards), is mentioned. 

 Also Hunting Bridge and Shepherd's Gutter (Bramshaw), "New 

 Eorest, 0. Eisner, Quart. Journ. Geol. Soc. vol. xviii. pp. 79 and 81. 



In the Quart. Journ. Geol. Soc. vol. xviii. 1862, the Rev. 

 0. Fisher specially notes the occurrence of A 7 , variolarius in the 

 Bracklesham series at AVhitecliff Bay, in his division xvii. (p. 70), 

 part of Prestwich's "no. 16," Quart. Journ. Geol. Soc. vol. ii. 

 p. 254 : in xiv. (p. 71), part of Prestwich's " no. 14 ; " in ix. (p. 72), 

 Prestwich's "no. 13." At Bracklesham Bay (p. 74) in the beds 

 numbered 22 and 21 and 20. Also (pp. 77-83) at Stubbington, 

 Hunting Bridge, Shepherd's Gutter, and King's-Garden Gutter. 



According to Dr. De la Harpe the A 7 , variolarius of the Barton 

 beds of Stubbington and White-Cliff Bay is the same as that of 



* Quart. Journ. Geol. Soc. vol. xviii. p. 78. 



t Mr. Keeping also has contributed some from this zone of N. variolarius* 

 which he finds to be 19 feet thick. 



\ This is the "Brook " locality of F. Edwards.
