CHAPTER VIII. 
PARTULA PRODUCTA Pease. 
Sharply contrasted with the preceding species, Partula producta occurs in a 
closely restricted habitat, in smaller relative numbers, and it is terrestrial; hence it 
is the complete antithesis of Partula otaheitana, which is abundant, widespread, and 
arboreal. In my own experience, producta was found in a single valley only, 
namely, Faarahi in the district of Mataiea, near the center of the southern sector 
of Tahiti nui. Garrett says (p. 66): 
“This species only occurred to my notice in one valley, on the southwest coast of 
Tahiti, where it is abundant, lurking beneath decaying leaves and under heaps of loose 
tones.” 
The map made by Garrett and published in Hartman’s paper (cf. text-fig. 2) 
seems to indicate a locality in Mataiea; yet when Garrett describes the various 
subspecies of ofaheitana (p. 49) he interjects a paragraph relating to this species, 
as follows: 
“Tt is worthy of remark that in that part of the district of Papieri [s7c] occupied by 
sinistrorsa, is also the headquarters of the terrestrial P. producta, a dextral species which 
is always edentate, and exhibits the fasciation of the former.” 
There is no political division named Papieri. Papeari is the district just to 
the east of Mataiea, while Papara adjoins it on the west, and is nearer the valley in 
which I found P. producta. Obviously Garrett meant either Papeari or Papara; 
that it was the former, we may be sure from the fact that sinistrorsa occurs in 
Papeari, while the relatives properly distinguished by Garrett as sinisiralis inhabit 
Papara. There still remains the possibility that Garrett did find producta in a 
‘valley to the east of Faarahi, actually located in Papeari, in which I failed to redis- 
cover the species; the probability of this supposition is not great, because every 
effort was made in my own collecting along the southern coast to find producta, 
which is somewhat elusive, even in Faarahi, on account of its terrestrial habit. 
Dextral banded snails were found, as we have seen, but they proved to be more 
or less abundant relations of the reversed sinistrorsa, etc. The true producta can 
not be confused with anything else, when it is examined carefully. In brief, the 
evidence tefds to prove that the single valley inhabited by producta in Garrett’s 
time was Faarahi, the same that in my experience is the present area of occurrence. 
Pease described P. producta in 1864, almost undoubtedly on the basis of speci- 
mens collected and forwarded by Garrett. The formal description 1s as follows: 
“P. t. elongato-ovata, dextrorsa, solida, compresse umbilicata, tenuiter et irregulariter 
longitudinaliter striata; anfr. v., plano-convexis, sutura impressa; apertura oblongo-ovyata, 
labro anguste rotundato; fusca vel flavicanter fusca, nigro-fusco trifasciata. 
“Long. 22, diam. 12 mill. 
“The above species is wholly terrestrial in its habits; the lip on mature or old speci- 
mens is united over the body-whorl by a callosity.”
