92 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 Velutina laevigata 

 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 Sal tees ; 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 following species were included —

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, Coleraine. This bird is of com- 

 paratively rare occurrence in Ireland.
