PRESIDENT’S ADDRESS. Paley s 
those of a plant of the same genus, the common nightshade or 
bittersweet of the hedges (Solanum dulcamara), and found 
that the moth fed as freely on it as on the potato. Mr. Selby 
described a caterpillar as large as that of the Death’s Head 
Moth, but differing from it in colour and in the shape of its 
markings, which he had also found on the potato. This cater- 
pillar, he thought, might be a variety of that of the Death’s 
Head Moth, but he had not been able to meet with any account 
of that species in which such a variety was described, nor was he 
aware of any other species to which it could be assigned. Mr. 
Alder, of Newcastle, read an account of the peculiar character of 
the animal, of Kellia suborbicularis, a bivalve mollusk not uncom- 
mon on our shores, shewing it to be a new type of form among 
the bivalves, differing from the others in having a large anterior 
tube. He also exhibited a drawing, and read a description, of 
the animal of Lepton squamosum, an allied genus, likewise very 
peculiar in its characters. He took the opportunity of Dr. 
Johnston being present to draw his attention to a curious new 
British Zoophyte, of very anomalous characters, found by Mr. 
Cocks, at Falmouth, and examined by Mr. Alder, in conjunction 
with that gentleman, during a recent visit to Cornwall. A 
drawing of the animal was exhibited to the meeting, and a ver- 
bal description given. Some account of its mode of development 
was also communicated. Dr. Johnston considered it quite dis- 
tinct from anything with which he was acquainted. Mr. Tate, 
of Alnwick, exhibited several specimens of mountain Limestone 
Fossils, remarkable for their perfection and beauty. This gen- 
tleman possesses one of the best collections of the fossils of this 
formation in the kingdom. After the business matters were 
concluded, and the rain had ceased, which fell heavily during the 
middle of the day, some of the party returned to the castle where 
they had spent a portion of the morning, and where, by the 
courtesy of the noble owner every facility was given for the ex- 
amination, both of its feudal remains and of its modern decora- 
tions. There is a small museum, containing objects of anti- 
quity, as well as specimens of most departments of Natural His- 
tory: amongst the latter are some very interesting fossil remains.
