Pease) appears to be the same as compacta Pse. (see Hartman, Proc. 
Acad. Nat. Sci. Phila., 1885, p. 209). Three specimens, one much 
shorter than the other and probably abnormal. In form the normal 
examples resemble large examples of the typical awrzculata, No. 4138, 
and still more some of P. compacta Pse., No. 4144; like the latter 
they have a prominent denticle. In color they are almost exactly like 
some of the specimens included under‘No. 4124, referred by Dr. Hart- 
man to approximata Pse. MS.,= vittata Pse. Probably this resemblance 
led Dr. Hartman at one time to refer the shells to afproximata Pse. 
(see Cat. Partula, 1881, p. 7), but the form, the strong denticle and 
the umbilicus partly open are characteristics of the aurzculata group. 
In Proc. Acad. Nat. Sci. Phila., 1885, p. 209, and in the later cata- 
logues, they are referred to P. auricu/ata. The mixture of characters 
suggests a hybrid. 
Nore.—Partula gonocheila Pfr., which Dr. Hartman places next to 
P. auriculata, is not represented by specimens in the collection. There 
is, however, a drawing of the type specimen in the British Museum by 
E. A. Smith (No. 4345). This was sent to Mr. Garrett and returned. 
Garrett wrote (Nov. 25, 1885): ‘‘ gonochei/a is undoubtedly a Mar- 
quesas species; it has no resemblance to Reeve’s figure and differs 
entirely from any form of ganymedes.’’ Reeve gives the habitat 
‘¢ Navigator Islands, ’’ and Dr. Hartman, in his MS. catalogue, says it 
is from Samoa. 
4143. ‘‘Partula bilineata Pse. (typical), Tahaa, Coll. Pse.’’ 
Nine specimens, variously banded, except one which is white and ap- 
pears to be an albino. 
4144. ‘‘ Partula compacta Pse. (typical), Raiatea, Coll. Pse.’’ Ten 
specimens, all whitish, except one which is ight brown. Cf. No. 4142. 
4145. ‘‘ Partula thalia Garr. MS. = addbreviata Pse., Raiatea, Coll. 
Pse. and Garr.’’ Fourteen specimens. ‘The species was published by 
Garrett in his ‘‘ Terrestrial Mollusca of the Society Islands,’’ Journ. 
mead. Nat. Se. Phila’, IX, p/ 60, Plate II], Fig. 46. 
4146. ‘* Partula thulia Garr. MS. (depauperated), Raiatea.’’ Four 
specimens. 
4147. ‘*Partula umbilicata Pse. (typical), Tahaa, Coll. Garr.’’ 
Sixteen specimens, varying in color from dark castaneous to white, 
sometimes with an obsolete darker or paler band at the periphery, or 
paler at the suture; one, larger and rather more obese than the 
others, is purplish-brown with a conspicuous pale peripheral band.
