Among those collected were Pecten Valoniensis, Avicula Contorta, several 
species of Axinus and Anatina, Cardium Rhceticum, &c, the Pectens 
and Cardiums being especially good. It was remarked that the Natica 
Oppelii, which is so common in the rest of the district, was comparatively 
rare in the Aust beds. 
The Cotham marble, lying just above the Avicula limestone, was the 
next object of examination, and from it were collected scales and teeth of 
fishes (Dapedius and Pholidophorus.) With these occurred an abundance 
of the elegant Entomostracon, Estheria minuta, so long regarded as a 
bivalved mollusc. As very little of the well known " bone-bed " had 
fallen, only a few of the fish-remains fell to the lot of the collectors, but 
one good tooth of the curious Ceratodus gibbus, and a few portions of 
spines of Hybodus were taken, the source of supply being entirely 
dependent on falls from the upper part of the Cliff. 
Before leaving, Mr. Stoddart directed the attention of the members 
to the instructive examples of " Faults " which occur in the Cliff. The 
nearly horizontal beds of limestone are so well marked by difference of 
colour, that the fracture and subsidence of the beds are plainly apparent. 
From each of these Faults flows a small quantity of water, which per- 
colating through the strata, finds a vent and trickles down the face of the 
rocks. Here those interested in microscopy, made a rich harvest of a 
singular stalked diatom Cocconema Cymbiforme, which here grows in 
great profusion. 
The members walked back to the New Passage Hotel, and after a capital 
tea, returned to Bristol by an early train, having thoroughly enjoyed a 
very pleasant and instructive ramble. 
ENTOMOLOGICAL SECTION. 
Monday, June 4. — The second excursion of the Section took place to 
Goblin Coombe, near Brockley. 
The members proceeded by 1.45 p.m. train to Yatton, walking from 
thence to the Coombe, and as the attendance was good, and the day every 
thing that could be desired, a large number of species were observed and 
captured. Among the species of Lepidoptera taken, were 
Vanessa C-Album. The speoimen of this insect taken had evidently 
hybernated from last autumn. 
L. Argiolus, common round holly. 
Thecla Rubi. 
B. Neustra, larva abundant on white thorn. 
L. Quercifolia, larva. 
E. Lariciata, imago on boles of larch. 
E. Indigata, on boles of larch.
