mens of the lanthina fragilis of Lamarck, the Helix 
Ianthina of Linnzus, collected from Oxwich Bay, to 
the west of Swansea, accompanied by a letter stating 
that the same shell, which is abundant in the Medi- 
terranean, had been found once before there in some 
abundance. Mr. Dillwyn considered the recording 
such facts of importance, as being likely to throw 
some light on the under-currents of the ocean. 
Mr. Bell exhibited three undescribed species of 
Land Tortoises, two of them very much resembling 
Testudo geometrica. 'To one of the present species, 
which Mr. Bell certainly thinks furnished La Cepéde 
with his erroneous description of T. geometrica, he has 
given the name of T. actinodes. It differs in the ab- 
sence of the small single plate at the anterior part of 
the margin. To another specimen, with conical scute, 
he has assigned the specific name of tentoria ; and to 
the third specimen (which he has had alive for some 
time,) he has given the name of pardalis: this, although 
resembling the Testudo indica, differs from it not only 
in colour, but also in the less revolute margin, and in 
the situation of the areole of the costal plates, which, 
instead of being exactly central as in T. indica, are in 
this species placed very near the superior margin. 
Mr. George Townshend Fox, F.L.S., exhibited from 
the Newcastle Museum the original specimen of the 
Green-headed Bunting, Emberiza Tunstalli of Latham, 
the E. chlorocephala of Gmelin, which now proves to 
be identical with E. hortulana, Linn. 
Mr. Yarrell, F.L.S., exhibited two specimens of 
Emberiza
