FOSSIL FOUxVU OS BAGSIIOT HEATH. 



Amongst the most common are Cladostephus spongiostis, G. vertidUatus, 



Sphacdaria cirrhom, and S. radicans, all of which are found in tolerable 



plenty on most parts of the coast. >S'. scoparia and the beautiful S. plumosa 



occur but rarely. JEdocarpvs siliculosus and E. littoralis are everywhere 



abundant. E. fasciculatas, tomeatosus, pusfillus, gramdatus, and spoerophorus 



are not uncommon at Cromer. E. IlincJcsice is found, sometimes plentiful, at 



Sheringham and other places on the north coast. E. Mertemil: I found a 



mutilated specimen of this rare Sea-weed on Yarmouth beach, in September, 



1848, but have not met with it since. E. aniphibim is not unfrequent in 



the salt-water ditches. E. hrachiatus: a specimen of this rare species was found 



at Caistor, in this county, by Mr. Dawson Turner, as far back as the year 



1801, and another was gathered in the clay ditches by Sir William Hooker, 



and which was figured in the "English Botany," (plate 2571;) neither of these 



specimens are, however, I believe, now in existence, and there seems to be 



much doubt whether the plant at present bearing the name of Ectocarpus 



hrachiatus is identical with the one found by Mr. Turner and Sir William, 



Mp'iotrichia filiformis is found parasitical on Asperococcus ecldnatus at Cromer, 



but by no means common.

FOSSIL FOUND ON BAG SHOT HEATH. 



I!Y O. S, HOUND, ESQ. 



The accompanying cuts show in two positions a Fossil which I found upon 

 the heathy ridge known as "Ribsdown," which lies to the left of the Great 

 Western Road, between the twenty-third and twenty-fifth mile- stones. It lay 

 amongst others which had been sifted away from the fine gravel by the side 

 of one of the numerous pits that have been opened upon the crown of this 

 range; and when it first attracted my attention, the slight turn which it had
