terminating with the Vertebrata. Although conversant with modern 
works, the author in some instances retains a certain nomenclature 
not quite in accordance with the present opinions ; it may, however, 
express his view of the subject. ‘Thus he retains Unio for the Palxo- 
zoic genus now called Anthracosia, and places Bellerophon under the 
Pectinibranchiate family Fissurellide ; retains Ammonites for species 
of Goniatite, and classes Hippurites, Radiolites and allied genera, 
under the Rudistes, or irregular Brachiopods, notwithstanding the 
valuable memoir by the late Dr. S. P. Woodward * on these forms, 
in which he clearly indicated their affinity to Chama, and classed 
some with that genus, as Diceras and Requienia, whilst on other 
forms he constituted the family of Hippuritide as Radiolites, Hip- 
purites, Caprinella, Caprina, and Caprotina. 
In the Trilobites Dr. Winkler has retained genera of Hawle and 
Corda as Crithias, Staurogonus, Acanthogramma, Tetracnemis, &c., 
which M. Barrande has since shown to be only different stages of 
growth of the curious genus Sao—a form which has been favoured 
with about ten generic and more than twenty specific names. How- 
ever, the catalogue is a useful synopsis of the contents of the fossil 
collection of the Haarlem Museum,

Bay. By R. A. C. Godwin-Austen, Esq., F.R.S., For. Sec. G. S. 
The submerged forest of Porlock Bay has been briefly noticed by 
Sir. H. De la Beche, but has not been sufficiently described, inasmuch 
as it illustrates more clearly than the larger forests of Bridgwater 
Level or Swansea Bay the nature and order of the oscillations of 
small amount which have taken place at times shortly antecedent to 
the present, and which were classified by the author in this paper as 
follows :—(1) The formation of an angular detritus and its accumu- 
lation at lower levels; at this period the land was at its highest 
relative elevation. (2) Forest-growths established on the detrital 
beds just mentioned ; the stumps of those forest-trees, some of which 
are of large size and great age, at present constitute the Submerged 
Forest. (8) Accumulation of freshwater mud (resulting probably 
from a depression of the land), by which the trees were killed. 
(4) Surface of water-plant growths on the mud-deposit, or nearly 
dry surface, on which the trees fell. (5) Area depressed below the 
sea-level, and sea-mud with Scrobicularie deposited. (6) Conver- 
sions of the surface into meadow-land at the level of the highest 
springs of the present day caused by re-elevation. (7) Shingle, 
heaped up on the meadow-land, and showing that the anos recent 
change has been one of slight depression. 
This succession of changes corresponds with that of numerous
