At the request of the author, we omit the description of the Families, 
Genera, and Species, as these can be found by referring to the Monograph, 
and only give his special remarks on some of the species and specimens. The 
author proceeded as follows : — 
Family I. MILLEPOEID^E. 1, Genus Fistulipora. F. minor, Mc.C. ; 
F. major, Mc.C. 2, Genus, Propora. P. cyclostoma, Phill. Family II. 
FAVOSITIDvE. 1, Genus Favosites. F. parasitica, Phill. 2, Genus 
Michelln ia. M. favosa, Goldf. Of this species the collection possesses 
eight specimens, from Masbury, Mendips, the Black Rock, Bristol, and from 
Knowle Quarry, near Brentry— it also occurs at Combe Hill, near Henbury. 
The specimen No. 1 has been in the hands of the authors of the Monograph, 
and I believe it to be the specimen figured in the Monograph, PI. 44, fig. 2. 
Of the second species of this Genus, viz., M. tenuisepta, Phill., the 
Museum possesses but one specimen, which is the one figured in the Mono- 
graph PI. 44. fig. 1, and is from Masbury, Mendips. M. megastoma Phill. 
is represented by three specimens, of which one —unfortunately without 
locality mentioned— is figured in the Monograph, PI. 44, fig. 3. The other 
two specimens are from Masbury, Mendips, and Black Rock, Bristol. M. 
antiqua, Mc.C. 3, Genus Alveolites. A septosa Flem. is represented 
by seven very fine specimens, six of which are from our own Rocks. No. 19, 
a Bristol specimen, exhibiting the external surface, is the original of 
Monograph, PI. 45, fig. 5. No. 22 also has been in the hands of the authors 
of the Monograph. A depr essa, Flem. Three of the six specimens of this 
species (Nos. 26, 27, 28,) have been thus named by the authors of the 
Monograph themselves, who have had them for examination, when preparing 
that publication; on comparing, however, all our Museum specimens of 
Alveolites, (which, without exception, are from our own district) and availing 
myself of the frequent opportunities of examining specimens of this genus, I. 
cannot help thinking that "A depressa, Flem. — A capillaris, Phill." is only 
an extremely small form of "A septosa, Flem." — a view which apparently 
McCoy is also inclined to adopt— See McCoy Brit. Pal. Fos3. p. 82." This, 
I think, is certain, that large specimens will sometimes exhibit a great 
diversity in the diameter of the calices, and that we possess almost all possible 
forms between the typical "septosa," and the equally typical "depressa." 
There is, however, one form of Alveolites occurring in our Rocks, of which 
we have two specimens in the collection, (Nos. 32, 33,) probably from Knowle 
Quarry, near Brentry, which I must certainly regard as a new and most 
distinct species, presenting a peculiar gyrate or labyrinthine outline in a 
cross section; I therefore have not given them a specific name in the 
catalogue.
