 parous Fish in Louisiana. This is an extract from Silliman's American Journal 

 for January, 1855. The fish is determined by Professor Agassiz to be the 

 Ptecilia multilineata, and is found abundantly in the lagoons in the immediate 

 vicinity of Mobile and New Orleans ; it is of very minute size its whole length 

 being only two inches. The specimen examined by Dr. Dowler contained twenty- 

 two foetuses, each about half an inch long. This family of fishes contains the 

 smallest representatives of the great type of Vertebrata. The Heterandria formosa 

 of Agassiz is, when full grown, not quite an inch long, and does not weigh more 

 than five grains. (Dr. J. E. Gray) On the Anomalous Oyster-shell described in 

 the " Annals" for February. This shell, which was described in the last number of 

 the " Annals" by Mr. Busk, appears to be that of an oyster growing on the inside of 

 a valve of Pholas Candida ; also, it appears that the shell of the Pholas must have 

 been that of a dead specimen, since it had growing upon it a Membranipora or 

 Flustra, which was impressed on the outer surface of the oyster ; and, hence, a 

 further proof is afforded, that the Pholas was external, and served as a mould to 

 the oyster-shell. We have found oysters which have grown upon the large oper- 

 culum of Fusus antiquus, which was completely enveloped in the shelly matter, and 

 projected like a wing from the side of the shell. (E. Claparede) On Actinophrys
