GEOLOGY AND PALAEONTOLOGY. 
Flint- Implement# near Folkestone, Kent . — The Rev. J. M. Mello gives the 
following brief description of a splendid locality for flint-implements, which 
may be worthy of the attention of a few of our readers. He says that during 
the course of the last month, he found at Folkestone several flint-implements. 
Along the sides of the footpath on the top of the cliff between Folkestone 
and Sandown, there is a low embankment, made probably of material col- 
lected off the adjoining fields : in this embankment the implements occur. 
They are mostly of the rude flake or “ scraper ” pattern. The first discovered, 
which was also the finest, was lying partly exposed on the top of the bank, 
and subsequently his brother and himself found several more not far from 
the same spot. He has little doubt that further search in the same bank 
would bring many others, and possibly finer ones, to light. 
The Coal at Korha . — In the May number of the Records of the Geolo- 
gical Survey of Lidia , it is stated that the coal is exposed in two places in 
the bed of the Hasdo river, just below Korba. The thickness was estimated, 
though roughly, from its dip and length of outcrop, to be at least 90 feet, 
including bands of shale and inferior coal. In order to obtain a more correct 
idea of the quality of the coal, small pits were dug ; these proved a minimum 
thickness of 50 feet of fair coal. Mr. W. T. Blandford, F.G.S., points out 
the best places for borings in order to ascertain the extent of the seam, as 
sufficient data are not known to justify the opening of a coal mine. Both 
the quality and mode of occurrence of the coal are considered favourable, 
and indeed, to surpass that near Chanda. 
The Mammalian Fossils of Ireland . — A very able paper, but one of too 
great length for an abstract, has appeared on this subject in the Geological 
Magazine for September. It is by Robert II. Scott, M.A., F.R.S., and deals 
with the different historical statements of any value that have been made 
in reference to the distribution of mammalia in Ireland. In regard to the 
presence of the elephant and other fossils, a great deal of valuable informa- 
tion exists in the paper referred to. 
A New Cephalaspis in America. — Mr. E. Ray Lankester describes an in- 
teresting specimen which was sent to him by Principal Dawson, of Montreal, 
Canada. The specimen presents in slight relief a small Cephalaspis, with 
head-shield and greater part of the body, and is much flattened. The shield 
appears to be larger in proportion to the body than in any British species. 
The orbits are not shown, and the matrix has not preserved the scales of the 
body with much distinctness, though it is possible to make out the lateral 
and marginal series. No trace of pectoral, dorsal, nor caudal fins is to be 
made out. This species clearly belongs to the section Eu-ccplialaspis as 
defined in his monograph of Cephcdaspidcc. Its best character as a species is 
to be found in the very fine, almost granular, tubercles which are preserved 
on some parts of the surface, and represent the apparently universally present 
tubercular ornament of the Osteostraci. These fine tubercles are more minute 
than on any British Cephalaspid, and, though seemingly not very well shown 
in this specimen, furnish a specific mark. 
Dorypterus Hofmanni. — Mr. Albany Hancock communicated a paper.
