This species resembles very much the following species, iV. Hockii, but is easily distinguished 

 from it by the shape of the chelifori and palps, and the much longer caudal segment. Only one single 

 specimen is known, which moreover is not quite full-grown.

 and the Atlantic, midway between the Faroe Islands and Iceland, 63° 4' L-at. N. 9 22' Long. W.; the
