of mammals. Mr. Wheeler reports 159 species of birds, and eight spe- 
cies of reptiles are noted by the Eev. T. A. Marshall. The same gen- 
tleman has contributed lists of 567 species of Coleoptera and 172 species 
of Hymenoptera. Mr. Beach has detected 71 species of MoUusca, and 
Drs. Abercrombie and Wilson, 87 species of Diatomaceae. Collections of 
several of the tribes investigated have been commenced to serve as a 
permanent record. It was also urged that it -would be exceedingly de- 
sirable that the same work should be done for the whole county which is 
being done for this district. 
NOTES AND QUEEIES. 
Highest Beds of the English Chalk. — For a long time the fossils 
from the Norwich chalk have been known to present slight, but peculiar 
distinctions from those of other districts ; and the Norwich chalk has j 
been often regarded as a higher stratum than any other in England. The 
recent description by M. Binkhorst (see "Eeviews," vol. vi. p. 240) of the ! 
fossils from strata at Maestricht, containing casts of univalve-shells, such i 
as occur in similar beds between Dover and St. Margaret's, showing their 
proximity to the highest cretaceous beds, has directed my attention 
afresh to a portion of one of the most interesting chalk sections in Eng- 
land, — that in the vicinity of Dover. Since William Phillips's admirable 
paper, read before the Geological Society in 1818, nothing has been pub- 
lished on the geology of that part of the Kentish coast; but, during a late 
visit, having obtained from the low cliffs at Kingsdown (left-side of view, 
Plate VIII.) specimens of Micraster cor-anguinum, unlike those usually 
found in the Dover and Maidstone Upper Chalk (see ordinary form, Fig. 6, 
Plate III ), but agreeing closely witht he gibbous variety so abundant in the 
Norwich chalk, I beg to solicit information from geologists of the cha- 
racteristic features and fossils of the highest beds of chalk in any locality 
with which they may be acquainted. As the beds in the Kingsdown clifis 
rise at a sharper angle than the general surface of the land, it is possible 
that the uppermost beds have more or less been sliced off by some denuding 
action towards Walmer Castle (to the right of the view, Plate VIII.). 1 
Mr. S. P. Woodward informs me the chief characteristic shells of the i 
highest beds of the Norwich chalk are — Pecten concentricus, Ostrea larva^ \ 
Terebratulina gracilis, Terehratella elegans, RhyncJionella ocioplicata, > 
Magas pumila, and Chama incequirostrata. The occurrence of these shells 
in any locality will be therefore indicative of the presence of strata repre- 
sentative of the Norwich beds. S. J. Mackie. 
DiDTMODON Vauclusianum. — Since my memoir on this subject was 
published, the specimen has been thoroughly cleaned out by Mr. Davies, 
of the British Museum, and he has distinctly shown that the interpretation, 
that the last tooth in the jaw w as the third molar, was erroneous. This 
tooth is therefore the second molar ; the one immediately preceding it be- 
ing the first ; and the fractured tooth, instead of being the first molar, turns 
out to have been the last premolar. The specific and generic distinction of 
the Didymodon is, however, not invalidated by the detection of this error 
on my part, which, as in all similar cases, I hope to be the first to point out.
