 Z. Inst. 1891, p. 287, t. 20, f. 5 o, 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 

 Kange, South Island, N. Z. 



G. ZEBRA Le Guillon, 1842. (See P. phlogophora, vol. I, p. 128.) 

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

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

 & J., 1854.
