RECORDS OF THE AUSTRALIAN MU8EUM. 
Papuina hindei, Cox. 
(PI. xxviii., figs. 7, 8, 9.) 
Cochlostyla Hindei , Cox, Proc. Linn. Soc. N. S.W. (2), ii., 1888, 
p. 1063, pi. xxi., figs. 1, 2. 
Ilelicostyla hindei , Pilsbry, Man. Conch., ix., 1894, p. 229. 
The most eastern point to which on assured, that is anatomical, 
grounds, the tribe of Belogona has been traced, is Waighiou, 
Dutch New Guinea, in the form of Helicostyla con for mis, 
Ferussac. On other and doubtful grounds this tribe is assumed 
to occur as far east as the Solomon Islands, in Cryst alloy sis, Ancey. 
With a view to deciding on more exact limits, I wrote to Madame 
Kolbe, of Ralurn, New Britain, enclosing a coloured drawing of 
Cochlostyla hindei, and requested her to procure the animal for 
study. Madame Kolbe, always a generous friend to this Institution, 
kindly responded by forwarding some well preserved material. 
The result of an examination of this is as follows : — 
Jaw (fig. 7) thin, ends rounded, smooth, centre crossed by 
weak ribs. 
Badula (fig. 9) of the type which Pilsbry has described for P. 
vexillaris, with rows meeting in the centre at an acute angle, and 
with enlarged and broadened cusps. 
Genitalia (fig. 8) without accessory organs on vagina. Tentacle 
retracted between the branches. Penis-sac long, flattened, with- 
out internal papilla. Retractor muscle attached to floor of lung 
cavity. Epiphallus long, slender and twisted. Spermatophore 
on long slender duct. 
This dissection must certainly effect the transference of Coch- 
lostyla hindei, from Helicostyla to Papuina as those genera are 
arranged in Pilsbry’s classic “Guide to the Study of Helices.” On 
this point the absence of a dart sac is conclusive and is supported 
generally by the structure of the male organ and of the dentition. 
Credit must be given to Brancsik, who in describing H. heimburgi , 
synonymous as Pilsbry suggests with the species before us, correctly 
indicated its systematic position by referring it to Geotrochus. 
I regard P. hindei as related to P. xanthochila, Pfr.
