median cavity. Near its base, the penis of most of the specimens 

 examined bears a larg-e saccate protuberance (hg. i, a. b, and f) ; 

 the vas deferens enters at the distal end of this protuberance and is 

 imliedded within the wall of the penis (at x, fi_G^. i. d). and empties 

 into the penial cavity just at or below the head of the penis 

 (exactly where could r.ot be determined from the specimens at 

 hand). In spcimens of Godzciuia haupncnsis (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 (PI. XXI\\ 4) is not 

 quite typical as the periphery is slightly more rounded than that of 

 Gould's figure. This specimen came from near Waiakoali X'alley. 

 Specimens from Kawaikoi \'alley ( liishop Mus. No. 16743) agree 

 very closely with Gould's descri])ti(in and figure.
