inuloides and rigidum, Foly;jonum viviparum, Glaucium luteum. Reseda 

 lutea and in Broomhall Woods Luzula nivea and Lilium Martagon ; 

 the latter probably introduced. 



Dr. Balfour also exhibited specimens of Rosa Brounonii in fine 

 flower, and stated that the plant had been allowed to spread its 

 branches on the slates of Mr. M'Nab's house, in the Botanic Gar- 

 den, and that it was then covered with a profusion of showy white 

 blossoms. 



Specimens of a secretion resembling mannite, procured from JEu- 

 calyptus dumosa, were exhibited. The specimens were sent by Sheriff 

 Cay, who had received them from near Melbourne, in Australia. 



MISCELLANEOUS. 



Kellia rubra. 



I HAVE stated, in the Catalogue of the Mollusca of Northumberland 

 and Durham, that the animal of this species has an anterior siphonal 

 tube, as in Kellia suborbicularis. While lately stopping in the Isle 

 of Man, I had an opportunity of examining the animal of this minute 

 s])ecies more carefully, and have ascertained that the anterior siphon 

 differs from that of K. suborbicularis in being open at the base, and 

 is in fact a prolongation of the mantle, folded over on the lower 

 side, like the siphon of the zoophagous Gasteropods ; while that of 

 K. suborbicularis is a perfect tube, though in both cases it performs 

 the same function, forming a channel for the ingress current of 

 water to the branchiae, as may be readily seen under the microscope. 

 1'his new modification of a remarkalile form in the bivalve mollusca 

 I wish to take the first opportunity of mentioning, as in the above- 

 named Catalogue I have instanced the similarity of the animals as 

 one argument for retaining this species in the genus Kellia in oppo- 

 sition to the opinion of M. Recluz, who forms of it, with other small 

 species, his genus Poronia. M. Recluz's description of the animal 

 of Poronia is, as applied to this species, entirely erroneous.

Notice of a fractured and repa/rec? Argonauta argo. 

 By C. B. Adams, Prof. 



The familiar examples of the repair of the shells of Mollusca are 

 interesting, since they illustrate the mode of growth of the shell. 



We have before us examples in which the wdiole of the last whorl 

 has been destroyed and reproduced. On account of the extraordinary 

 relations subsisting bet^veen the animal and the shell in the genus 

 Argonauta, a fractured and repaired shell possesses more than usual 

 value. 



In the collection of shells in the cabinet of Amherst College is an 

 individual of the Argonauta argo, which appears to furnish an addi- 

 tional argument in support of the opinions which are based on the 

 researches of Madame Power. In this shell a portion has been
