20 AUSTRALASIAN ANTARCTIC EXPEDITION. 
Type Locality.—Station II., Lat. South 66° 55’, Long. Hast 145° 21’, off the Mert 
Glacier Tongue, Adelie Land; 288-300 fathoms, ooze; bottom temp. —1-8° C.; Decem 
her 28th, 1913; one adult 2 specimen, two juvenals. 
Fig. 13.—WM. adelieana. 
Radula. 
Remarks.—The short wide body, enormous eyes, scanty umbrella, short robust 
arms, characteristic funnel organ, and distinct radula of this species are the features 
which more especially seem to forbid its union either with any of the previously described 
members of the genus or with any of the remaining forms captured by the Austral]- 
asian Expedition. In many respects WM. adelieana bears a certain resemblance to the 
M. turqueti of Joubin, but the description of the latter, though lacking in detail, fails in 
several points to tally with our specimens. Unfortunately Joubin does not describe 
the funnel organ or figure the radula of his type, else it might not be necessary to leave 
to the future the final disposition of these forms. 
Two very small specimens of the same genus [S.S.B. 439] were taken with the type, 
and J have small doubt that they are conspecific with it. Though neither has a total 
length of as much as two centimeters, they agree in most of the essential particulars. 
The larger of the two is probably a male.
