collection, proceeded to add that they were valuable from comprising- so 
large a number of type specimens. 
These were described and figured by Sowerby, in an appendix to the 
classical monograph of Dr. Fitton, on the " Strata below the Chalk." 
(Dr. Fitton' s paper bears the date of 1835, though it had been read to 
the Geological Society in 1827.) 
This collection of Blackdown fossils was formed by the late Mr. Miller, 
but on his decease, it was acquired by the Bristol Philosophical Institution, 
and then lent by the Managers to Dr. Fitton, for the sake of being named 
by Sowerby. 
In arranging the fossils of the Museum, the author of the present paper 
said that he regretted to find that they had been so indifferently catalogued, 
that many of them bore erroneous names, while others had not been named 
at all, and on compiling a list it was found that some had been lost. 
The results of his catalogueing are the following: — 
Out of a total of 144 species (being 137 named and 7 un-named) mentioned 
by Dr. Fitton, there were described and figured, 57 as. new species : a few 
of these have however since been degraded from the rank of species. 
Of these 57 types, there are at present in the Museum 49, so that 8 have 
been mislaid, viz. 
Astarte multistriata. Phasianella pusilla. 
Nassa lineata. Pollicipes loevis. 
Natica granotfa Psammobia gracilis. 
Petricola nuciformis. Terebratula dilatata. 
Besides the 57 types of new specieSj there were figured 6 others, but not 
for the first time: none of these are mis" » 
There remain then out of a total of 144, still 81 : these were not figured, 
but simply cited as "existing in the Miller Collection: again of these 6 are 
missing, viz. 
Corbula sp. 
• sp. 
Cytherea parva. 
Solarium conoicleum. 
Terebratula pisum. 
Ammonites dentatus. 
The Paleontological evidence of the Blackdown deposit was next discussed. 
First was remarked, that of the Ammonites all except 3 occurred in the 
Gault, but none is the Neocomian: so that the important group of 
Ammonites go to prove that the;3e beds have much nearer relation to the 
Gault than to any other deposit.
