Endodonta varicosa, Pfeiff'er, sp. 1852. 

 (PI. XXII. fig. 7). 



The correct reference of this species is now the following : — 



Syn. — timandra, Suter (non Hutton, 1883).

Dentitio n. — Suter, Trans. N. Zeal. Inst. Vol. xxiv. p. 293,

H a b. — South Island : Akaroa (Suter)^ Dyer's Pass, Riccarton 

 Bush, near Christchurch. 



Not e. — This species replaces E. timandra in the South Island. 

 I have not seen it from the North Island. 



As mentioned above the radula described and figured in Trans. 

 N. Zeal. Inst. xxiv. shows quite exceptional abnormal forms of 

 the racliidian and lateral teeth, but it is from E. varicosa and 

 not timandra, Hutt. I fortunately received a living specimen 

 fiom Bank's Peninsula, which proved to possess a normal radula, 

 and I wish to give here a short description of it, accompanied by 

 a figure. 



Radula (fig. 7) tongue-shaped, with transverse straight rows of 

 teeth 13 — 1 — 13, of which three may be considered as laterals, 

 and three as transition teeth. The central and laterals are veiy 

 much alike, the base quadrangular^ slightly longer than broad, 

 sinuated in front. Reflection tricuspid, the median cusp with its 

 short cutting point reaching to the posterior end of the base ; the 

 side-cu.sps are short, rounded, each with a very small cutting 

 point. In the lateral teeth the median cutting point extends
