bright orange spots. The part covered by the shell was of a darker 

 and somewhat bluish-green, bearing dull orange spots and also bands 

 and blotches of dull red bordered with white. One of the specimens 

 had a few dark violet spots here and there ; in the other specimen 

 they were absent. 



As preserved the animals are much hardened and contracted, but 

 not withdrawn entirely into the shell, the margins of which are still 

 covered with the various flaps of the body. Most of the flesh is quite 

 hard and deep dark brown in colour ; only the liver is soft and 

 greenish. The shell is white, fragile, inconspicuously striated, and 

 covered with a yellowish periostracum. It is shaped much as in 

 Pease's figure (as reproduced in Pilsbry's "Manual") but is slightly 

 narrower in proportion to its length. The rhinophores, gill, etc., 

 appear to have dried up and could not be found.

Two median teeth of Haininma siviiUima. 

 A lateral tooth of Ha-minoea sintzllijita. 



The labial armature is much as in ff. natalensis, and consists of 

 slightly bent rods ; they are hooked at the tip, and slightly thickened. 

 The radula consists of 35 and 32 rows in the two specimens. In one 

 there are from eight to ten teeth on each side of the rhachidian tooth; 

 in the other the number of laterals was not found to exceed eight. The 

 rhachidian tooth is broad with three cusps, which vary somewhat in 

 shape, and have a sort of hood at the top, but have not rounded out- 

 lines and are thin or pointed. The laterals are hamate. The shaft is 

 at first very erect, and then bends rather suddenly backwards. 

 (Text Fig. 5). The first lateral is broader than the rest, and its hook 

 is straight or slightly inclined away from the rhachis, whereas the 

 hooks of the others are inclined towards the rhachis. This difference 

 of direction gives the middle of the radula a confused appearance.
