are more robust and the whorls more swollen than the typical varia. The most common 
variety is luteous, or straw-yellow, sometimes pale fulvous with the lip more or less 
stained with violaceous brown. ‘The variety with a white peristome is not uncommon, 
and a beautiful variety, with a very dark violaceous black spire and wide band of the 
same color on the middle of the body-whorl, is much more infrequent, as well as the 
one with a dark spire, without the band. The dark variety with yellowish band, so 
common in the type and the Faahiti shells, is rarely found elsewhere. The first men- 
tioned variety, which comprises nearly 75 per cent. of the specimens, is probably 
Pfeiffer’s P. glutinosa, which Pease quotes as a variety of P. varia. Dr. Hartman, in his 
Catalogue of Partula, records it as a distinct species, and in Observations on the Genus 
Partula cites the Navigator and Solomon Islands as its habitats; in the same paper 
he states, in his remarks on Pease’s duplicates, that ‘““P. glutinosa, Pfr., in one quart was 
J 
uniform in size and color,” which coincides with the Huaheine shells. Both Pease 
and Dr. Cox have assured me that they have never received Pfeiffer’s glutimosa from 
either the Navigator or Solomon Islands. The shells referred to were collected by me 
on Huaheine, and, as just mentioned, were by Pease regarded as P. varia, var. glutinosa. 
Pfeiffer, who erroneously cites the Solomon Islands as the habitat of the latter, remarks, 
in his fourth volume, that Reeve’s P. varia, fig. 176, is the same as glutinosa. 
I am unacquainted with Pease’s varieties simplex and perplexa—the latter quoted 
on the authority of Dr. Hartman, but not recorded by the former author in his list 
of Partula. 
I have followed Dr. Hartman in adding Pfeiffer’s mucida to the synonymy of varia, 
which he says is represented in the British Museum by a dark variety of the latter 
species. ‘The description and measurements harmonize well, but it appears strange 
that Pfeiffer should have compared his species to P. filosa, which belongs to an entirely 
different type, instead of to the well-known varia. 
I cannot agree with Dr. Hartman in his affiliation of Pease’s P. strigata, a Mar- 
quesas (“ Marquesas? Rve.,” Hartman) species, with P. varia, which is an entirely 
distinct species. Pease’s shells were collected by a native missionary residing on 
Woapo, one of the former group, which is 850 miles distant from Huaheine. 
The only species likely to be confounded with varia is Pease’s P. assimilis (= P. 
Cookiana, Mouss.), inhabiting Rarotonga, one of the Cook’s Islands, 600 miles from 
the habitat of the former species. Dr. Hartman records it (Cat. Partula) as a valid 
species, and very correctly makes P. Cookiana, Mouss., a synonym. He also records 
it (Obs. Gen. Partula, p. 179), and remarks: “ This shell may prove to be a local 
variety of P. varia.” On page 181, 1. ¢., he doubts Cookiana being identical with 
assimilis, and on page 189, 1. c., makes both assimilis and Cookiana pure synonyms 
of varia. Pease, in his description of assimilis, remarks: “Comparing large numbers, 
the above is more abbreviate, whorls more convex, and the aperture narrower.” The
