about so many, and it must be understood that absolute uniformity is not 
usually intended. I have the figures of a large number of species besides 
those published, and hope to discuss the results. 
Jullien and Calvet’s terms ‘ anter’ and ‘ poster’ are now adopted. Jullien & 
Calvet, ‘Bry. prov. de l’Hirondelle,’ p. 17, 1903, divide the aperture into 
‘anter’ and ‘ poster,’ and the operculum into ‘ porta’ and ‘ vanna.’ The anter 
is the distal part of the aperture and is closed by the porta; and the poster 
is the proximal part and is closed by the vanna. The division is made by an 
imaginary line between the two points at which the operculum is hinged. 
According to Jullien the vanna closes the opening of the compensation sac, 
but for his explanation and the function of the two parts the reader is referred 
to the work mentioned.

Aiétea recta, Hincks, Ann. Mag. Nat. Hist. ser. 3, vol. ix. p. 25, pl. 7*. fig. 3; Waters,

Miss Jelly’s Catalogue. 
This is probably the most widely distributed species of tea and has often 
been mentioned under other names. The specimens in this collection are 
small and do not permit of further study. This is the species in which the 
ovicells are known *.
