Mr. W. H. Benson on new Species of Helix. 491 
papillose viscous covering that enwraps the putamen is evidently 
analogous to the short tomentum imbedded in a pulpy meso- 
carp, as seen in Jateorhiza, Odontocarya, and Hematocarpus, and 
the fleshy envelope in Anomospermum. The description given of 
the form of its embryo is precisely that found only in the Hetero- 
cliniee. From the evidence collected from all sources, which 
appears to me undeniable, the following generic character has 
been formed. , 
Burasata, Thouars.—Fiores dioici. Masc. Sepala 6, ovalia, 
concava, 2-serialia, 3 exteriora minora. Petala 6, oblongo- 
ovata, breviter unguiculata, carnosa, 2-serialia, exteriora paulo 
- majora, apice eroso-denticulata. Stamina 6, petalis opposita: 
filamenta carnosa, subbrevia, gradatim incrassata, apice geni- 
culato-clavata: anthere oblonge, introrse, 2-lobz, lobis ad- 
natis, imo paulo divaricatis et subimmersis, horizontalibus, 
rima laterali utrinque dehiscentibus. Ovaria rudimentaria 
nulla.— Fem. (char. ex cl. Decne.) sepala et petala ut in mase. 
Stamina abortiva 6. Ovaria 3, gibbosa, 1-locularia, ovulo 
unico angulo ventrali appenso. Stigma sessile, truncatum. 
_ Drupe 3, carnose, supra gynecium auctum insite, ovate : 
putamen papillis tectum, mesocarpio viscoso indutum, ovatum, 
plano-convexum, 1-loculare, condylo coneavo in loculo pro- 
tenso: embryo intra albumen copiosum fere rectus, cotyledont 
bus planis, foliaceis, in locellis distinctis divaricatis, radicula 
supera, stigma spectante. 
Frutices Madagascarienses, glabri, cortice rimoso ; folia longe pe- 
tiolata, palmatim 3-foliolata, foliolis ovatis, lanceolatisve, inte- 
gerrimis, coriaceis ; racemi pauct, axillares, fasciculati, floribus 
parvis, breviter pedicellatis. 
1. Burasaia Madagascariensis, P. Th. ;—Madagascar. 
2. —— gracilis, Dene. ;—Madagascar. 
3. congesta, Decne. ;—Madagascar.

to Botany,’ vol. i.

XLVII.—Descriptions of new Species of Helix and Pupa from the 
Colony of the Cape of Good Hope, By W. H. Benson, Esq. 
Tue following species were chiefly received from Mr. Edgar 
Layard, who has been assisted in collecting shells by several 
correspondents in distant parts of the colony, 
1. Helix Arnotti, B., n. sp. 
H. testa obtecte perforata, subconoideo-depressa, irregulariter oblique
