 iii, p. 325, t. 78, f. 11-13. Ampidoxa corneofulva SUTER, Trans. N. 

 Z. Inst. 1891, p. 287, t. 20, f. 5 a, b (shell), 6, 7 (jaw and dentition). 



This species was referred by Hutton to Hyalina cellaria, but 

 Suter has identified it with specimens of a Calymna from Nerger 

 Range, South Island, N. Z.

Hutton is doubtless correct in including as synonyms H. phlogo- 

 phora Pfr., 1849 ; H. flammigera Pfr., 1852 ; H. multilimbata H. 

 & J., 1854.
