40 DR. J. C. COX ON A NEW HELIX. (Jan. 26, 
This light olive-brown compressed species, which is characterized 
by the posterior side-angle being somewhat winged, is named after 
Henry Evans, Esq., an old colonist and a relative of one of the au- 
thors, who has derived considerable assistance in collecting speci- 
mens of natural history from his willing co-operation.

HELIx FORBESII. 
H. testa obtecte wmbilicata, globulosa, solida, sub epidermide 
lutescente alba, lineis fuscis cincta ; spira obtusa ; anfractibus 
septem ; apertura lunato-rotundata, intus alba ; peristomate 
undique expanso, margine columellari superne dilatato. 
Shell with a covered umbilicus, globular, solid ; white beneath a 
yellowish epidermis, encircled with brown lines ; spire obtuse ; whorls 
seven ; aperture lunar rounded, white within ; lip expanded through- 
out, columellar margin dilated at the top. 
Hab. Port Denison, Queensland. 
This shell, which I have named after the late Prof. Edward Forbes, 
and of which I have a large number of specimens, was found on the 
trunks of the native fig-trees at Port Denison. I believed it at first 
to be only a local variety of H. lessoni; but on more careful investi- 
gation I have found it to be a very well-marked vew species, and I 
am unable to find any record of its having been before described.
