Note on the occurrence of the Opah, or King -fish, on the coast of Norfolk. On the 

 Gth of July a fine specimen of the opah {Lampris guttalus) was brought to Norwich, 

 having been left by the tide on the beach at Eccles, on the western coast of Norfolk. 

 It was a male fish, and weighed between four and five stone. The stomach was emp- 

 ty, and some parts of the flesh were bruised by the action of the waves upon the beach. 

 Where this was not the case, the flesh was found quite eatable, and had a very sweet 

 and rich taste. The flesh of the opah has been sometimes described as being red, like 

 that of the salmon, but in the present case, it was white, with a tinge of yellow. The 

 iris of the eye, which has also been described as being red, in this specimen was of a 

 silvery white colour. Three other specimens are on record as having occurred on the 

 coast of Norfolk : two of these, which are mentioned in Paget's ' Natural History of 

 Yarmouth,' occurred near that town, the one in December, 1823, and the other in No- 

 vember, 1828: and the third was obtained at Hunstanton, in July, 1839, and is now 

 in the Wisbeach Museum. — J. H. Gurney ; Norivich.

Note on DuvaVs Fossil Terebratula. I am indebted to the kindness of Professor 

 Duval Jouve, of Grasse, in the South of France, for the above sketches of two fossil 

 shells in his collection, each of which he supposes unique, but at the same time ex- 

 presses a very decided opinion that both are referrible to one species. The drawings
