the acquisition of this specimen, a short paper, which he proposed 

 to entitle " Additional remarks on the Genus Lagotis, with some 

 account of a second Species referrible to it." 



Mr. Reeve exhibited specimens of two Shells, which he regarded 

 as previously undescribed, and compared them with the species most 

 nearly related to them, which he also exhibited. 



The first of thera is characterized by Mr. Lake as follows : 



CyprjEA subviridis. Cyp. testd ovatd, pyriformi, subventricosd ; 

 dorso convexissimo, subviridi, Jasciis duabus tribusve latis, fulvo 

 brunneoąue varie picto ; basi convexd, pallidd ; margine subin- 

 crassato, rufescenti-brunneo, extremitates versūs subproducto ; ore 

 lineari, sublato, postice recurvo, dcntibus submagnis subdistan- 

 tibus, columelld convexd : long. ll, lat. 4, ak. -į^ poli. 



Hab. 



This shell seems to partake of the characters of Cyp, Errones and 

 Cyp. pallida ; having for the most part the colouring and marking 

 of the former, and the form of the latter: it is, hovvever, specifically 

 distinct from either. It is of a ventricose pyriform shape ; the back 

 is of a light green colour, variously painted with yellovvish brown ; 

 and the margin is of a reddish brovvn colour, darker towards l^e 

 extremities. — L. 



The second species is thus characterized by Mr. Reeve : 



LuciNA RUGiFERA. Luc. testd rotundūtd, lenticulari, convexiusculd, 

 albicante spadiceo-rufescente concentrice subfasciatd ; striis ra- 

 diatis elevatis aliisque concentricis rugosd ; intūs albd ; ano tri- 

 gono, impresso, minimo : long. 2^, lot. 2, alt. 1 poli. 



Hab. ad oras Novae Hollandiae. 



This shell is closely allied to Luc. tigerina, (Cytherea tigerina, 

 Lam,,) and appears at first sight to be the var. 3 of that species 

 (Lam., Anim. sans Vert., nouv. ed., p. 219): but upon examination 

 it is foimd to difFer, principally in the longitudinal strice being more 

 elevated, and crossing the transverse strice, and in the interior being 

 perfectly white : it is also from a very difFerent locality. There is 

 in the collection of Mr. Cuming a specimen of the variety of Luc. 

 tigerina above mentioned which answers exactly to Lamarck's de- 

 scription. — L. A. R. 



Specimens were exhibited, partly from the collection of the Rev. 

 F. W. Hope, and partly from that of Mr. Westwood, of various 

 Hymenapterous Insects, vvhich Mr. Westwood regarded as new to 

 Science. They were accompanied by the following characters by 

 Mr. Westwood :
