noticed also that collections of fossils 

 gathered by a farmer at Hindover, and by 

 a resident at Denton, contained nearly 

 as many examples of the large form of 

 Conulus as of EcJiinocorys and Micraster. 

 The small rounded shape-variation, which 

 Dr. Rowe calls conica, I found, although 

 sparingly, in the zone of Marsupites, as he 

 states. 



The shape - variations of EcJiinocorys 

 scutatus proved exceedingly useful, except 

 where crushing had destroyed the value of 

 this index. I found two specimens of the 

 large ovate form of this fossil in a band 

 of Cardiaster pillula, near the base of the 

 zone of Actinocamax quadratics, on Seaford 

 Head. I also procured a specimen of the 

 dwarf pyramidal form of EcJiinocorys in 

 the zone of Actinocamax quadratus at 

 Rookery Hill, Bishopstone, where it oc- 

 curred some 20 feet or so above the base, 

 of which Dr. Rowe says it is very charac- 

 teristic. Micraster cor-anguinum occurs 

 well above the base of the zone of Actino- 

 camax quadratus at Hindover, where I 

 found several specimens, at the same level 

 as Cardiaster pillula. These were of the 

 usual thin-tested type, and I was only 

 able to extract them in a fragmentary 

 state. Epiaster gibbus, not at all a common 

 fossil in Sussex, I found in two localities : 

 one near the top of the zone of Micraster 

 cor-anguinum at Denton, and the other 

 well up in the Marsupites-Zone at Seaford 

 Head. 



I must also record a single imperfect 

 specimen of a belemnite resembling Acti- 

 nocamax verus, in the zone of Actinocamax 

 quadratus, in the base of the chalk-pit near 

 Seaford Cemetery. Dr. Rowe, who has 

 seen this specimen, thinks that it is more 

 like Actinocamax verus than anything else, 

 especially the inflated form from the zone 

 of Micraster cor-anguinum. 



From the scarcity of Cardiaster pillula 

 in this quarry and the decidedly gibbous 

 form of EcJiinocorys scutatus, which occurs 

 in a band about 10 feet from the base, it 

 is judged that the pit is considerably 

 above the base of the zone of Actinocamax 

 quadratus. It is noteworthy, however, 

 that Actinocamax verus has not before 

 been found in the A.-quadratus Chalk of 

 the South of England.
