median cavity. Near its base, the penis of most of the specimens 
examined bears a large saccate protuberance (fig. 1, a, b, and f); 
the vas deferens enters at the distal end of this protuberance and is 
imbedded within the wall of the penis (at x, fig. 1, d), and empties 
into the penial cavity just at or below the head of the penis 
(exactly where could not be determined from the specimens at 
hand). In specimens of Godwinia haupuensis (fig. 3, d) the penis 
is pyriform, widest near the base, and the vas deferens enters the 
wall just below the middle of its length. 
The right tentacle does not pass between the male and female 
genital organs but between these organs and the buccal mass and 
under the main nerves leading to the genitalia. 
The central and lateral teeth, as pointed out by Godwin- 
Austen, are unicuspid, but the cusp bears cutting points on both 
sides. In the centrals these cutting points are nearly opposite to 
each other, while in the laterals the inner and less distinct point is 
considerably higher than the outer. There are 4 perfect laterals, 
2 to 4 transitionals, and from about 18 to 32 aculeate unicuspid 
marginals, the number depending on the age and species of the 
snail. 
The members of this subfamily are known only from the 
island of Kauai. They are rarely found in abundance and are 
usually taken in thick, damp ferny jungle above the thousand-foot 
level, crawling on damp dead leaves. A very few specimens have 
been found on the under surface of fronds of low-growing ferns.

This species has been collected on the highlands north and 
northwest of the Waimea Canyon. It is more abundant on the 
northern rim near the Waiakoali and Kawaikoi drainage basins 
than farther west. The specimen figured (Pl. XXIV, 4) is not 
quite typical as the periphery is slightly more rounded than that of 
Gould’s figure. This specimen came from near Waiakoali Valley. 
Specimens from Kawaikoi Valley (Bishop Mus. No. 16743) agree 
very closely with Gould’s description and figure.
