502 Miscellaneous. 



Annelida. 



Planaria arethisa, Dalyell, Observations on Planarise, p. 8"), 

 f. 11-14. — Apr. 27, 1851. A Planaria, which I found attached to 

 the under-side of a stone at Shanes Castle Park, Lough Neagh, and 

 brought away for critical examination in a linng state, appears to be 

 of this species, to a history of which nearly thirty pages are devoted 

 in the work quoted. My specimen when in repose is A\ lines long 

 by an average of 2 lines broad ; its eyes are visible without the aid of 

 a lens. Planaria nigra, Miill., P. torva, Miill., and P. lactea, Miill., 

 were attached to the same stone. 



Entozoa. 



Tetrarhynchus megacephalus was found in the abdomen of a large 

 specimen of the Blue Shark in Dublin, by Dr. Carte, Curator to the 

 Museum, College of Surgeons, Ireland. (Communicated by Dr. Bel- 

 lingham, July 1848.) 



Echinorhynchus gigas, Rudd. — Specimens supposed to have been 

 obtained in Ireland, but respecting which there is no positive note, 

 have been for many years in the Museum just named. (Communi- 

 cated by Dr. Bellingham, July 1848.) 



BOTANICAL INFORMATION. 



Sale of the Extensive lierharinm and of the Books of the late George 

 Gardner, Esq., F.R.S., Director of the Royal Botanic Gardens, 

 Peradenia, Ceylon. 



In consequence of the lamented death of Mr. Gardner, instructions 

 have been given to the executors to sell without resers'e the entire of 

 the above-mentioned Collections of this gentleman, which have re- 

 cently been received in London for that purpose. 



The whole Gardnerian Herbarium, that is, the Collection arranged 

 by himself for his own use, it is wished should be disposed of sepa- 

 rately and by private contract ; it is admirably arranged, and as fully 

 and correctly named as probably any of the like extent, all the speci- 

 mens upon the best stout white demy folio paper, measuring 16 inches 

 long by 10^ broad. 



Every genus is included in one or more envelopes of the same 

 paper, in folded sheets, and marked on the outside with the name of 

 the genus, that of the natural family, and numbered according to the 

 numbers and arrangement in Endlicher's Genera Plantarum. The 

 specimens are invariably in excellent condition, no trace of insects 

 having been seen in any of them, and we have reason to believe that 

 they are all poisoned : from as accurate a calculation as has yet been 

 made, there are about 14,000 papers containing specimens, and we 

 think we are within bounds when we say that there are 12,000 spe- 

 cies of Phsenogamous Plants and Ferns. The Collection is, as may 

 be anticipated, extremely rich in Brazihan and Ceylon plants, gathered 

 mostly by himself, during 5|- years' travels in the former country 

 (and they are the authority for his many published species), and 

 during his four years' sojourn in Ceylon. It further includes numerous 

 plants prepared by himself in Mauritius, and a still more extended 

 assortment from the Neilgherries ; a rich collection of Malacca plants
