the sponge rock, without affecting the level top of the Red Rock. 
These spaces are filled with soft red matter, or with sand." 
By far the most important of Professor Seeley's papers from a 
palaeontological standpoint is the one published in the Annals in 
1864, on the Fossils of the Hunstanton Red Rock." As in a previous 
paper Prof Seeley remarks that the rock at Hunstanton may be 
divided into three parts, or three well-marked layers of nearly equal 
thickness, and these may be numbered in descending order, 1, 2 and 
3. Then follows a list of about eighty-seven named species, and 
nearly twenty more fossils indicated by generic names only, or 
varieties. The whole of these fossils were collected by the author, 
and are now deposited in the Woodwardian Museum at Cambridge. 
In this list Prof Seeley introduces a new feature of great interest to 
the palseontologist, by locating the fossils, as far as he was able to 
do so, in the several layers. Certain species are peculiar to the 
lowest (No. 3). Belemnites attenuatus and minimus; Plicatula 
sigillina : Terebratula capillata, hi^olicata, and Dutempliana, range 
through the whole of the layers ; a still less number of species range 
through layers 2 and 3, and by far the gTeater number are found in 
the top bed only. It was unfortunate for me that when writing my 
" Monograph of the Polyzoa of the Red Chalk of Hunstanton,"t this 
paper was overlooked, especially so, as an acquaintance with it would 
have prevented the error on p. 456, of the Monagraph, and have 
saved me from after annoyance. In Prof Seeley's list I find the 
following Polyzoa mentioned : the new species being described in the 
last of the series of Hunstanton papers in 1866.}:
