fated from the "Annales des Sciences Naturelles." The Secretary also 

 communicated to the Society some notes on Lythram Salicaria, re- 

 marking that he had observed this plant in several stations in the 

 neighbourhood of London, with the leaves variably situated on the 

 stem; and exhibited specimens in which the plant had alternate op- 

 posite, and leaves three in a whorl. These observations, together 

 with other peculiarities noticed by Mr. Dennes, led to an inter- 

 esting discussion. Mr. Daniel Cooper exhibited and offered for dis- 

 tribution to the Members several of the rarer plants found about 

 Reigate, Surrey, which he had that day expressly collected for the 

 purpose ; and stated that It was the intention of several of the Mem- 

 bers to collect in a similar way the rarer plants of the vicinity of 

 London, and exhibit them at the monthly nights of meeting through- 

 out the summer. Mr. Cooper called the attention of the Members 

 to specimens of Paris Quadrifolia, of which there were plants having 

 from three to seven leaves upon the table, but in no instance had he 

 observed more than five portions of the calyx, and not, as recorded 

 by some authors, a division of the calyx for each leaf found upon the 

 stem. Mr. Gray noticed a peculiarity in the flower of the Adoxa 

 Moschatellina ; and expressed his approbation of the plan of pro- 

 curing living specimens of the rarer plants for distribution at the 

 summer monthly meetings, as it would enable many of the Members 

 to examine and make such observations upon the plants as they 

 might think necessary, and who might be prevented from collecting 

 them at the proper period. Among Mr. Cooper's collection were 

 specimens of the early Orchideous plants, comprising Ophrys apifera, 

 O. muscifera, Orchis ustulata, Platanthera bifolia, Lister a ovata, 

 Acer as Anthropophora, &c. Specimens of Leucogum JEstivum were 

 also exhibited by the Secretary, which were obtained from the old 

 station in Greenwich marshes, opposite Blackwall.

TWO RECENT SPECIES OF TRIGONIA. 



The Trigonia of Van Diemen's Land, first described by Lamarck 

 (of which we have an original specimen in the British Museum, 

 presented by that justly celebrated naturalist), and the one disco- 

 vered by Mr. Stutchbury, in Port Jackson, New Holland, have been 

 considered the same species. The series of specimens from the first
