ZOOLOGICAL AND BOTANICAL ASSOCIATION. 281 



After admiring this nameless beauty in many aspects, I retired with 

 it to a dark room, and tried by various devices to induce a brilliant 

 display of irritation ; but my efforts were vain. It had been taken in 

 Strangford Lough, county of Down, and forwarded to me by Mrs. Ward, 

 of Tubber-na-Carrig. On being informed that it was rare and highly 

 acceptable, that lady, with the most considerate attention, forwarded to 

 me, on the ensuing day, two additional specimens, which, being sent by 

 a special messenger, reached me in about three hours after leaving 

 Strangford, and exhibited in full perfection the outline of the animal, 

 with the chamber surrounding the peduncle. The name of Turris con- 

 strict a seems applicable to this Medusa. Its specific application has re- 

 ference to the form of the swimming bell, which, among the several spe- 

 cimens examined, varied exceedingly. The species was not observed in 

 Strangford Lough, except once, though carefully looked for. 



The Rev. Professor Haughton, F. R. S., read a paper — 



ON SOME FOSSIL PYRAMIDELLID^ FROM THE CARBONIFEROUS LIMESTONE OF 

 CORK AND CLONMEL. 



The following fossils were placed at my disposal by Mr. Joseph Wright, 

 of Cork ; and as some of them are new forms, and others excellent speci- 

 mens of rare fossils, they appeared worthy of being exhibited before this 

 Society. 



The genus Loxonema was formed by Professor Phillips as a provi- 

 sional genus for the reception of many of the Palaeozoic shells, previously 

 named Melania, Turritella, &c. ; and the genus Macrocheilus was sug- 

 gested by the same geologist as a convenient substitute for the Buccinum 

 of the older writers. Both these genera are properly placed by Wood- 

 ward among the PyramidellidflB. There is considerable difficulty in 

 ascertaining the precise conchological affinities of the fossil shells of the 

 older rocks, owing to the circumstance that the mouths of the shells are 

 generally broken off or concealed by stone. It is, therefore, in many 

 cases impossible to pronounce absolutely on the identity of a fossil with 

 a recent genus ; and the most that can be done under these circumstances 

 is to give it the name of the genus to which it appears most closely 

 allied, attaching at the same time a specific name, suggestive either of 

 the locality in which it was found, or of some other genus to which it is 

 also allied.
