1862.] MR. G. KREFFT ON FURINA TEXTILIS, 149 
Length of carapace, nearly 4 lines; breadth at umbo, rather more 
than 2 lines. 
» Hab, Lake Winnipeg, N. America (IW. Caldwell, Esq.). (Mus. 
Brit.) 
7. LiMNETIS GouLDII, Baird. (Plate XV. figs. 7, 7 a, 7 6, 7 ¢.) 
Carapace nearly quite globular, ventricose, and of a light horn- 
colour. Surface of valves smooth, not ribbed, ard covered entirely 
with numerous very small hollow punctations exactly resembling 
those on the top of a thimble. The point to which the adductor 
muscles are attached is yery marked, being slightly prominent, and 
very smooth and shining; and the branchial canals on the surface 
of the valves are strongly exhibited. 
This species resembles very much L. wahlbergii of Lovén, from 
Port Natal. In addition, however, to the total difference of habitat, 
this species differs from the one described by Lovén in size, being 
double the dimensions of it. The animal, too, differs in some par- 
ticulars; but as all the specimens I have examined are males, and 
the one figured by Loven is a female, I do not know how far these 
differences may be merely sexual. 
Diameter of carapace, about 14 line. 
Hab. Fresh water at St. Ann’s, twenty miles from Montreal, 
Canada. Collected by Charles Gould, Esq., June, 1857. (Mus, 
Brit.) 
6. Nore on Furina textinis. By Gerarp Krerrr, ACTING 
Curator Austr. Mus. 
During my rambles in the neighbourhood of Sydney I have found 
a number of small Snakes, varying in length from 8 to 12", and an- 
swering to the description given by Duméril and Bibron of Furina 
textilis. None of the specimens obtained have exceeded 16! in length ; 
and I have been naturally anxious to procure the young of this spe- 
cies. During two years I was unsuccessful, and I began to think 
at last that this Snake was only the immature form of some other 
species, which supposition became a belief when some months ago 
I found an egg containing as large a specimen of Furina tevtilis 
as I had ever met with before. On further investigation I found 
that the distinct bands and black spots of this Snake faded with the 
growth of the individual, and apparently vanished altogether in old 
specimens. As the egg and young in my possession are of a size 
generally produced by Snakes from 3 to 4 feet in length, and as I 
have a series of specimens in which the disappearance of the bands 
and markings may be clearly traced, I do not hesitate to assert that 
Pseudonaia textilis is only a young Snake. Inviting the serutiny of 
more able naturalists than myself to this fact, I beg to refer at the 
same time to my collection forwarded to the International Exhi- 
bition, specimens Nos. 66 and 40, which I believe to be identical. 
I have since forwarded a full-grown adult Snake of this species to
