than any which I recollect. The colours are arranged somewhat like 
those on Bulimus vexillum. 
Figure 65, shell with the animal; 65 a, the shell above, and 65 b, 
the base of the shell, enlarged ; 65 ¢, natural size. ; 
Hevrx mraminata (Gould). 
Testa depresso-globosa, imperforata, tenuis, translucida, alba, epider- 
mide tenuissimo stramineo induta ; spira depressa, anfractibus qua- 
tuor convexiusculis, ultimo subangulato : apertura rotundata, ampla ; 
columella planulata, acuta ; labro everso. 
Anima greatly developed, and elongated so as to equal three dia- 
meters of the shell in length. Its colour is white, with sky-blue 
reflections. There is a dorsal line of blue on the neck, and one passes 
back from each tentacle. he shell is placed far back upon the 
animal. 
Suet depressed, globose, imperforate, thin and translucent, of a 
pure white, covered with a very delicate straw-coloured epidermis. 
There are about four whorls, forming a low, nearly flat spire, the last 
faintly angular at the periphery. Aperture large, rounded ; the co- 
lumella flattened, acute edged; lip everted ; beneath tumid, imper- 
forate. 
Diameter one inch; axis two-thirds of an inch. 
Obtained from a tree at the island of Mangsi, Straits of Balabac. 
I am somewhat in doubt as to the validity of this species. In shape 
it is like H. intorta, excepting that the last whorl above the columella 
has less altitude, and there are no revolving dusky bands. From #H. 
Valenciennesii it differs in being less globose, in having a thinner 
columella, differently directed, and no sutural line.
