Theoretical Astropetrology.-The few facts known under this head, (i. e. which relate to the origin and formation of meteormasses, the changes they have undergone from the various conditions in which they have been placed, and speculations regarding any traces of life they may contain,) have induced me to postpone any detail of them, to a fuller report on this branch of knowledge, which I hope to submit to the Association at a future period.

XXXVI-Catalogue of Shells Inhabiting Tampa Bay and other parts of the Florida Coast; by T. A. CONRAD. Bivalves. Amphidesma variegata, Lam.; rare. Mullet Key of Tampa Bay.-A. radiata, Say; found alive on Mullet Key.-A. orbiculata, Say; rare. Mullet Key.-A. equalis,* Say; common. Mullet Key. Arca zebra, dredged up alive in Tampa Bay. Artemis elegans,* Conrad; rare. Mullet Key.-A. concentrica, Lam.; common. This and the preceding species have probably been regarded as identical, but in every stage of growth there is a uniform and marked difference; the former species being more orbicular and convex, and having much more remote and distinct grooves, a character as obvious on the young shells as on the adults. It is much the rarest of the two species, and occurs fossil in the Miocene of North Carolina. Anomia ephippium,* Lin.; common. Keys of Tampa Bay. Arca scapha? common. Mullet Key.-A. incongrua, Say; Mullet Key.-A. ponderosa, Say; rare. Mullet Key. Avicula; rare. Egmont Key, Tampa Bay. rare. Astarte lunulata,* Con. ; common. Egmont Key, Tampa Bay. -A. flabella; rare. Egmont Key, Tampa Bay. Cardium citrinum, Wood; common. Mullet Key.-C. isocardia, Lam.; common. Mullet Key.-C. magnum, Born.; common. Mullet Key.-C. bullatum, Lam.; rare. Mullet Key. -C. Mortoni, Con. Very abundant on the shores of Tampa Bay, and I do not remember finding it on any of the Keys. The allied species, C. citrinum, on the contrary, occurs only on the Keys. The former is readily distinguished by its far less size, want of polish, and the almost invariable purple spots which mark the interior of C. Mortoni. The latter lives as far north as Massachusetts, but the citrinum is confined to the southern coast. Carditamera floridana, Con. Common in Tampa Bay frequenting oyster beds, (Cypricardia nodulosa, Mighels.) I did not find it on the Keys of Tampa. It also occurs on the shores of Key West and of Lignum Vitæ Key, East Florida. There are several Miocene species of this genus in Virginia, Maryland, SECOND SERIES, Vol. II, No. 6.-Nov., 1846. 51 and North Carolina. It is very distinct from either Cardita or Cypricardia. Cardita tridentata,* Say; rare. Egmont Key. Chama arcinella,* Lam.; abundant on north end of Mullet Key. Cytherea gigantea, Lam. Abundant. Mullet Key.-C. maculata, Lam.; rare. Mullet Key. Corbula limatula, Con. Deep water, between Tampa Bay and Pensacola. Cyrena carolinensis, Bosc. Head of Tampa Bay.-C. Floridana, Con. Common on the bay shores. It prefers salt water, whilst the former species invariably confines itself to the scarcely saline estuaries of rivers. Donax variabilis, Say. The most abundant of all the bivalves of Florida, burrowing in the sand. As the surf rolls over them they come to the surface, burying themselves instantly as the waves recede.—D. — A small ovate species. Coast of Florida near St. Joseph's Bay.-D.-. Longer than D. variabilis, with an arched base. Egmont Bay. Lucina nassula, Con. Egmont Key. Egmont Key. Nearly allied to the Miocene L. cribraria, Say.-L. pennsylvanica, Lam.; rare. Mullet Key.-L. squamosa,* Lam.; rare. Mullet Key.-L. tigrina, Lam.; rare. Mullet Key.-L. floridana, Con.; very abundant. Mullet Key and bay shores. This is the analogue of the Miocene L. anodonta, Say. It is never so thick and variable in form nor so large as many of the fossil species.-L. edentula, Lam.; rare. Mullet Key.-L. trisulcata, Con.; rare. Egmont Key. Mactra ovalis? Common. Egmont and Mullet Keys.—M. lateralis,* Say. Abundant. Egmont Key.-M. fragilis, Lam. Common. Bay Shores. Bay shores.-M. latera- Modiola demissa, Dill. Abundant. lis, Say. Bay shores.-M. papyria, Con. americana, (M. tulipa, Lam.) St. Joseph's Bay. Mytilus hamatus, Say. Common. Manatee river, Tampa. -M. cubitus, Say. Common. Manatee river, Tampa. Meleagrina. Rare. Egmont Key. A small species with profoundly elongated scales. Nucula acuta,* Con. Dredged up in deep water in the Gulf of Mexico.-N. eborea, Con. Rare. Egmont Key. |
