The zocecia are not much raised, and below the aperture there is a minute 
triangular avicularium. However, this in a few cases, both from the Red 
Sea and from Manaar, develops into a large spathulate aviculariam. The 
operculum has a dark thick border, and the poster is formed of a large are 
of a circle. The ovicell is closed by the operculum. 
The margins of the aperture are not much raised, but there are specimens 
in the Manaar collections with a decidedly raised peristome and_ similar 
avicularia, though with large pores round the border of the zocecia instead of 
the uniform perforations. This form, which may have to receive another 
generic name, also occurs from New Zealand (A. W. W. coll.). It is scarcely 
necessary to say that L. Montferrandi is only placed provisionally with 
Lepralia, and it would fall under Cribrella, Jullien & Calvet, if we are to 
accept that genus as based upon satisfactory characters. It belongs to the 
Lepralia galeata group, but is much smaller than the species described from 
Chili in my ‘ Belgica* Antarctic Report, p. 48. Probably one or two 
genera with nearly round apertures will have to be separated from Lepralia. 
This species I have from Japan ; it has the size and shape of the operculum 
identically the same as in the Red Sea specimens, also those from Manaar 
are within a trifle the same size. The Lepralia acuta, Ort., L. obtusata, Ort., 
and Schizoporella pellucida *, Ort., all seem most closely related and require 
further study. The Lepralia cribrosa, Maplestone (fossil, Victoria, Australia), 
differs from L. Montferrand: in having an avicularium.
