Section MYODOCOPA, 
Family POLYCOPIDA. 
Genus Potycopr G. O. Sars. 
PoLycorr cincutata G. S. Brady. 
Polycope cingulata G. 8. Brady, 1880, Rep. Chall. Zool., vol. I, pt. III, p. 170, 
pl. XXXV, figs. 7a-d. 
Observations.—The locality whence the type specimen came is lost. It is, 
therefore, doubly interesting to record the present examples from East of Tasmania, 
and off Kaiser Wilhelm II Land, Antarctic. The specimen from the latter locality 
has the thickened flange very conspicuously sulcated on the inside. 
Occurrence——No. 60 (12th December, 1912), 1,300 fathoms. No. 139 (27th 
January, 1914), 328 fathoms.
