Mr. Bunbury believes Lasiandra Jlssinervia, DeC, to be merely a variety 

 of L. Fontanesiana ; and Clidemia urceolata and C. biserrata to be one spe- 

 cies. He describes variations in character occurring in Lasiandra protece- 

 formis. DeC, Clidemia urceolata, DeC, C. longibarbis, DeC, Tetrapteris 

 acutifolia, Cav., Bignonia venusta and Neurocarpum angustifolium, Kuntli. 

 He thinks it possible, however, that his plant may differ from the latter, as 

 the flowers are resupinate, a character which could hardly have escaped M. 

 Kunth ; he therefore proposes for it the following character, should it prove 

 to be distinct : — 



Neurocarpum resupinatum, frutescens erectum, foliis trifoliolatis : foliolis 

 ellipticis oblongisque retusis mucronulatis supra glabris subtus pallidis 

 pilosiusculis, pedunculis subbifloris folio brevioribus, floribus resupinatis. 

 Hab. ad Botafogo, prope Rio de Janeiro. 



Specimens of the plants noticed in this memoir were included in a col- 

 lection presented to the Society by Mr. Bunbury some years ago.

 with descriptions of a new Genus and some new Species." By J. 

 O. Westvvood, Esq., F.L.S. 



This paper contains a brief enumeration of the species of the re- 

 markable family of Paussida, with some additions and corrections to 

 Mr. Westwood's Monograph of it, published in the 16th volume of 

 the Society's Transactions. 



He proposes to exclude from the family the genus Trochoideus, an 

 examination of the cibarian organs having proved that genus to be- 

 long to the Endomychidce ; and states that he is now acquainted with 

 four, if not five, species belonging to it, viz. 1. Troch. cruciatus, 

 Dalm. ; 2. T. Dalmanni, Westw. ; 3. T. Desjardinsii, Guer. ; 4. T. 

 Americanus, Bucqu. ; and 5. ? 7". Hopei, Westw. The last-named spe- 

 cies he has seen in Mr. Hope's collection : it is from New Grenada, 

 and is possibly identical with T. Americanus.
