Cordylochele malleolata Sars, Pycnogonidea, 1891, p. 45. PI. IV. Fig. i, i a-k. 



Occurrence. The Ingolf-stations are: 4, 9, 32, 126, that is to say the southern part of the 

 Norwegian Sea, the Greenland Sea, the Denmark Strait, and far up in the Davis Strait. The depths 

 were between 200 and 300 fath. 



Distribution. According to Sars, Pycuogonidea , 1891, p. 48, it is a genuine arctic form, 

 from the Kara Sea, Spitzbergen, and Beeren Eiland. By the Ingolf it was taken somewhat farther
