PROCEEDINGS OF SOCIETIES. 
larger than any Irish specimens the President had seen, and he mentioned that he 
had obtained many specimens of this rare shell off the coast at Youghal, about 
thirty years since. In the collection was also a series of the Hypothyris (Tere- 
bratula) psittacea, a very rare shell on the British and Irish coasts. Dr. Ball 
directed attention to the fact, that several of the specimens produced, seemingly of 
species familiar to us, were yet of larger dimensions ; thus the Yelutina lsevigata 
and Farcimia are greatly larger than are to be met with in this country; the 
Farcimia surpassing the large variety, or species, familiar to collectors of zoophytes, 
as much as that does the small ordinary form. 
Dr. Ball also stated that some of the Crustacea were probably undescribed, 
as he had not yet been able to identify them. He finally exhibited the skull 
of an Esquimaux, the most northern human remains found by Commander 
M‘Clintock; cast of the horns of a musk ox, and referred to some birds in the 
University Museum, all the generous contributions of the gallant gentleman, who 
is now again on his arduous duties. 
Mr. Walpole considered that he had seen as large specimens of the Farcimia, 
near the Saltees ; and that the Buccinum Humphreysianum exhibited obscure undu¬ 
lations which he had not observed in Irish species. 
Mr. Carte, Curator of the Museum of the Royal College of Surgeons, exhibited 
a specimen of Lepidosiren annectens. He had received the specimen from Mr. 
Brian, who had brought it from the Gambia. When it reached him it was enveloped 
in dry mud; having been incautiously placed in cold water, it perished. It lay 
coiled up, covered with mucus, in a sort of chamber in the mud ; from its mouth 
there appeared to be a tube for respiration. 
Mr. Carte called attention to some of the anatomical peculiarities of his spe¬ 
cimen, which were strongly against its being classed with fishes. He exhibited 
some remarkably well-executed drawings of the specimen, and promised further 
to communicate to the Association on the subject. 
The President had laid on the table the principal authorities in reference to the 
much disputed position of this most interesting creature, and concurred in the view 
Mr. Carte had taken. 
The Rev. Joseph Greene exhibited some rare English Lepidoptera, among which 
the following species were included— 
Notodonta dictsea. 
„ dromedarius. 
„ dodonea. 
,, trepida. 
Spselotis ravida. 
Polymmatus argiolus. 
Lithosia aureola. 
„ miniata. 
Sesia fuciformis. 
Pcecilocampa populi.

Ceropacha or. 
„ ocularis. 
Ptilophora plumigera. 
Spselotis pyrophila. 
Spselotis prsecox. 
Cirrsedia xerampelina. 
Xanthia aurago. 
,, citrago. 
Hadena rectilinea. 
,, cucubali. 
Heliothis marginata. 
Plusia inscripta. 
„ interrogationis. 
Catocala sponsa.

Lophobora sexalisaria. 
Tephrosia consonaria. 
Anticlea rubidaria. 
Hemithea bajularia. 
„ vernaria. 
Pericallia syringaria. 
Geometra papilionaria. 
Some inquiries having been made as to the best method of killing Lepidoptera, 
the President and Dr. Allman suggested chloroform. 
Mr. Greene considered bruised laurel leaves quite as efficacious, and said that they 
have the advantage of being always at hand. 
Mr. Lamprey noticed that a specimen of the glossy Ibis (Ibis falcinellus) had 
been obtained by W. Doherty, Esq., at Bushmills, Cqleraine. This bird is of com¬ 
paratively rare occurrence in Ireland.
