I cannot side with Sars in considering the W. mrxtum of Krøyer as a good species, but 
must agree with Wilson in uniting W. grossøpes and N. mrxtum; perhaps I may also be allowed to 
point out that Hansen in his list of Danish Pycnogonida seems inclined to approve of such a union. 
Occurrence. The Ingolf-stations 2, 31, 87, 95, 127 state it to be taken in the Davis Strait, 
the Denmark Strait, as well midway between Greenland and Iceland as nearer to the latter island, 
in the mouth of «Bredebugt»; further also in the Greenland Sea, and finally as far south as the 
boundary of the Norwegian Sea midway between the Fare Islands and Iceland. The depths were from 
50—752 fathoms (Danish). 
Further it is found at the Zoological Museum from many localities. When it has been called 
by other. names than that of MW. grossipes, the name in question has been added in a parenthesis.
