Phillips, as President cf the Geological Society of London, and also 
one in Professor Haughtou's Appendix to the ' Voyage of the Fox 
in the Arctic Seas.' Professor Phillips, when discussing the influ- 
ence of ancient currents of the sea, remarks that " only a small pro- 
portion of the fossils of A^orth Devon occur in South Devon;"* and 
Professor Haughton says, " I do not believe in the lapse of a long 
interval of time between the Silurian and Carboniferous deposits, — 
in fact in a Devonian period. 
" The same blending of corals has been found in Ireland, the Bas 
Boulonnais, and in JJevonshire, where Silurian and Carboniferous 
forms are of common occurrence in the same localities, "f 
It should be remembered that the statement with which we have 
here to deal is, " that the blending of Silurian and Carboniferous 
corals" (the word is not fossils) " is of common occurrence in Devon- 
shire." 
I have consulted such registers as I have been able to command, 
and have thrown so much of their contents as bear on the questions 
before us in the following tabular form ; for which, of course, no 
higher value is claimed than attaches to the original documents. 
The materials have been mainly derived from Professor jNLorris's 
' Catalogue of British Fossils,' published in 1854, in which are 
embodied the results of the labours of Mr. Lonsdale, Professors 
Phillips and M'Coy, and Messrs. Edwards and Haime. The liberties 
taken with the ' Catalogue ' have been but few; such, for example, as 
the removal of the Devonian Sfrojiiatopores from the class Zoophyta 
to xVmorphozoa, SphcBronites tessellatus from Echinodermata also to 
Amorphozoa, and the addition of a few localities to those already 
registered. 
I have great pleasure iu acknowledging the prompt and kind assist- 
ance of Mr. Salter, of the Greological Museum, Jermyn Street, Lon- 
don, in certain matters on which I consulted him. 
Every geologist is, of course, aware of the numerous and elaborate 
tables and ratios introduced by Professor Phillips in his ' Palaeozoic 
Fossils of Devon and Cornwall,' when discussing questions akin to 
those under consideration. In the preparation of this paper the 
author has in no way made use of the valuable data these tables 
contain. 
It appears from the three left-hand columns of figures, headed 
"Totals," Table I., that, taken together, the five areas have yielded 
three hundred and torty-seven species, belonging to ninety-seven 
genera and forty-nine families, of nine classes of animals ; namely, 
three classes of the sub-kingdom Kadiata, one of Articulata, and five 
of Mollusca ; hence fifteen of the twenty-four classes into which the 
existing animal kingdom is commonly divided are totally unrepre- 
sented in the series, as is the entire vegetable kingdom also. It 
may be as well to stale here that, in conformity with Morris's 
* Quarterly Journal Geol. Soc. vol. xvi. p. xl. 
t ' Voyage of the Fox/ Appendix No. iv. p. 387.
