Page 94 - Landscape-Stone," and in another band of Limestone, only a few feet higher, some of which are said to be beautifully preserved, and could not have been long subject to the action of the waves, it is supposed by Mr. Brodie, that this part of the Lias may have been formed in an estuary, which received the waters of some neighbouring coasts, and which brought down the remains of insects and plants.
Page 94 - Landscape-Stone ' have afforded a quantity of remains. In some slabs the insects were found imbedded together in masses. In one slab, Mr. Higgins is stated to have detected as many as 30 small Beetles. "From the frequency of such delicate creatures as insects in the 'Landscape-Stone,' and in another band of Limestone, only a few feet higher, some of which are said to be beautifully preserved, and could not have been long subject to the action of the waves, it is supposed by Mr. Brodie, that this...
Page 10 - ... though they are removed from them by several points ; the two anterior feet are not annexed to the head, and, like the succeeding ones, depend upon their particular segment. The feet are always fourteen in number, unguiculate.d, and without any vesicular appendage at their base. The under part of the tail is furnished with appendages which are very apparent, and in the form of leaflets, or vesicular purses. Of these, the two...
Page xvii - Hope,1 now preserved iu the Oxford Museum. Among others is a specimen " from Coalbrook Dale, which has very much the appearance of some large Caterpillar, furnished with rows of tubercles, to which setae or bristles were attached, as in the case of the caterpillar of our common English Emperor Moth (Saturnia Pavonia minor) : unfortunately the specimen is imperfect at each end, and therefore it is impossible to judge of the appendages of the head or tail. It will be seen that there appear to be distensions...
Page xiii - Professor JW Westwood believed that most of these insects were aquatic in habit, and that they affected the neighbourhood of fresh-water streams, over which they hovered during life and became submerged after death. The last author remarks...
Page 61 - At Apperley, near Wainlode Cliff, remains of insects have been found in plenty, many small slabs, three or four inches square, exhibiting several elytra and wings, and a few small Beetles. "From the Insect-Limestone, near the village of Hasfield, Gloucester, many elytra of Coleóptera have been obtained.
Page 59 - Coleoptera, which are by no means uncommon, and a few wings bearing a close resemblance to some I have previously detected in the Wealden. There are others also which are stated by Mr Westwood to be allied to Chauliodes, one of the Neuroptera, and referable to the same group as the Wealden wing. Shells are not common, but Ostrea, Unio, and a small species of Modiola are the most abundant ; there are also, though rarely, a few specimens belonging to the genus Monotis. Small fragments of carbonized...
Page 78 - ... Marquis of Northampton and Mr. Pratt. 5. " On certain Calcareo-corneous Bodies found in the Outer Chambers of Ammonites." By Mr. HE Strickland. These bodies are semicircular, very thin, slightly concave plates, usually corneous, sometimes more or less calcareous. Mr. Strickland regards them as having formed laminar appendages to the animals of the Ammonites, adapted to discharge some unascertained function. They resemble the two expanded valves of Aptychus, soldered together ; and the author...
Page xviii - ... connecting distendable membrane. The lateral series of long, slender and evidently articulated appendages seem also to throw a doubt on the Insect being a Lepidopterous larva. These appendages' have some remote analogy to those of a portion of the segments of Squilla, but this is only in appearance, and not a real relationship. The dark line which runs down the back seems quite analogous to the great dorsal vessel or heart of the Caterpillars.
Page 80 - The Plants (Naiadita lanceolata) and Cypris, are here much more abundant, the surface of the slaty portions being covered with remains of the latter Crustacean, which are collected together in masses of some thickness, just as we find them in many fresh-water deposits. The occurrence of numerous bivalve shells of a Crustaceous animal, so closely resembling the common Wealden
