332 RECORDS OF THE AUSTRALIAN MUSEUM. 
This group was early segregated, though not named, by G. and H. 
Nevill% as for a section of Olathurella. By Boettger% it was confused 
with Paraclathwrella, but Smith, who better appreciated the real relation- 
ship of Hemidaphne, remarked on the difference of the apex. 
Besides the Australian species here discussed, the following extra- 
limital species may be included in this genus:—Pleurotoma lirata Reeve, 
1845; Pleurotoma reeveana Deshayes, 1863—Pleurotoma concinna Dunker, 
1856 (not Scacchi, 1836)—Clathurella tumida Pease, 1867; Pleuwrotoma 
subula Reeve, 1845; and Daphnella supracancellata Schepmann, 1913.

HiBMIDAPHNE CYCLOPHORA Deshayes. 
(Plate liv., fig. 168.)

p- 228. 
The Australian shell is 10 mm. long, and therefore considerably larger 
than the type, which is only 7 mm. long; but judging from literature, 
this form may be counted as a variety of the species of Deshayes. To 
facilitate recognition it is here figured.
