Hah. Wilhelm Land (?); Queen Mary Land, 610 metres. 



Known only from 2 specimens, both obtained by the 'Aurora' off Shackleton Ice- 

 shelf (65° 6' S, 96° 13' E). The type was 211 mm. in total length. 



The specimen of 69 mm., identified by Pappenheim as Pagetodes antarcticus, from 

 the Winter Station of the ' Gauss ', may belong here.
