Pease) appears to he the same as compacta Pse. (see Hartnian, Proc. 

 Acad. Nat. Sei. Phila., 18S5, p. 209). Three specimens, one much 

 shorter llian llic other and probably abnormab In form the normal 

 e.xamples resemble large e.xamples of the typical aiiriculata, No. 4138, 

 and still more some of P. coinpacfa Pse., No. 4144; like the latter 

 they have a jjromincnl denticle. In color they are almost exactly like 

 some of the specimens included under No. 4124, referred by Dr. Hart- 

 man to appro.xiiiiata Pse. MS.,-= vittata Pse. Probably this resemblance 

 leil r)r. Hartnian at one time to refer the shells to approximata Pse. 

 (see Cat. Partula, 1881, p. 7), but the form, the strong denticle and 

 the umbilicus partly open are characteristics of the aiiriculata group. 

 In Proc. Acad. Nat. Sci. Phila., 1885, p. 209, and in the later cata- 

 logues, they are referred to P. aiiriculata. The mixture of characters 

 suggests a hybrid. 



Note. — Partula gonocheila I'Ir., which Dr. Hartman jjUu es next to 

 r. aiiriculata, is not represented by .specimens in the collection. There 

 is, however, a drawing of the type sj^ecimen in the British Museum by 

 E. A. Smith (No. 4345). This was sent to Mr, darrett and returned. 

 Garrett wrote (No\-. 25, 1885) : "■gonocheila is undoubtedly a Mar- 

 quesas species; it has no resemblance to Reeve's figure and differs 

 entirely from an\- form of ganyinedes.'^ 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 aj)- 

 pears to be an albino. 



4144. " Partula compacta Pse. (typical), Raiatea, Coll. Pse." Ten 

 specimens, all whitish, except one which is light brown. Cf. No. 4142. 



4145. " Partula thalia Garr. MS. = ahbrcviata Pse., Raiatea, Coll. 

 Pse. and Garr." Fourteen specimens. The species was published by 

 Garrett in his " Terrestrial Mollusca of the Society Islands," Journ. 

 Acad. Nat. Sc. Phila., IX, p. 69, Plate III, Fig. 46. 



4146. "Partula thuliaQiZ.xx. MS. (depauperated), Raiatea." P^our 

 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.
