The drawing of the generative system was kindly supplied by 

 Mr. R. Murdoch, of Wanganui, who describes it as follows : — 



"The generative system (Fig. 6) is very similar to that of other 

 members of the genus, and the characteristic features scarcely differ 

 from those in Flammulina and Endodonta. The penis (jt>.) is com- 

 paratively large, with the distal portion foh^ed upon itself ; the retractor 

 muscle (r.m.) is inserted at the apex. The vas deferens (v.c?.) also 

 separates from the apex ; it is a very slender tube and forms a loop 

 round the distal portion of the penis. The receptaculum seminis (r.s.) 

 is a narrow tube with a globose termination. The large pouch-like 

 sacculation (sc.) of the uterus appears to be a very constant feature 

 in all three genera; the prostate and female ducts {ovd.') branch from 

 its lower, anterior portion, and the former is partly concealed in 

 the lower, concave surface. Other organs scarcely call for notice; the 

 right ocular retractor passes between the branches of the genital system.

3, Endodonta (Chakopa) ochra, n.sp. Figs. 2, 2a. 



Shell discoidal, nearly flat, pale, shining gold when first matured, 

 becoming wan and creamy with age ; whorls 4, rounded, last slightly 

 descending ; protoconch If- whorls, smooth, silvery when first 

 matured, soon becoming white and opaque ; remaining whorls ribbed 

 15 per millim., silky at first, afterwards rough, 3-4 growth-lines 

 between ; ribs sloping backwards near the suture, then straight and 

 again backwards over the periphery, slightly sinuated below, micro- 

 scopically, finely reticulated ; suture well marked ; periphery narrowly 

 rounded ; umbilicus perspective, \ of the diameter ; aperture oblique, 

 rotundly lunate, much excavated by the penultimate whorl ; lip simple, 

 margins converging ; columella arched ; base rounded ; foot of animal 

 bright yellow. Alt. '75, diam. 3'5 mm.

4. Endodonta (Charopa) chrysaugeia, n.sp. Figs. 3, Za. 



Shell discoidal, flat, bright golden brown when first matured, silky, 

 whorls 4, rounded, last not descending, increasing rapidly ; proto- 

 conch 1^ whorls, smooth, silvery, remaining whorls radiately ribbed, 

 20 per millim. with 3-4 growth-lines between ; ribs straight from 

 suture, then backwards over periphery and straight below, in the 

 brephic stage the ribs slope backwards ; suture deep ; periphery 

 rounded ; umbilicus perspective, \ of the diameter ; aperture slightly 

 oblique, inclined to be quadrate ; lip simple, margins converging ; 

 columella nearly vertical ; base rounded ; animal with the foot bright 

 orange. Alt. '5, diam. 2 mm.
