This species is very much like A scorhync hits abyssi of Sars Pycnogonidea, 1891, p. C33, pLXIV, 



and I was long doubtful whether I should set it up as a particular species. Among the 



chai I the diagnosis I may especially point to the shape of the oculiferous tubercle, having 



Found its dorsal side produced in the middle to an acute angle with sharp teeth on the sides. 



The neck is also much shorter, the point of the rings of the trunk is drawn back quite to the 



the caudal segment is horizontal, not directed downward, and the armament of the 



inner edge of the second tarsal joint is much more spread than in Ascorhynchus abyssi. I have also 



pointed out that the sensory in the palps is distinctly discernible, and that only the three hindmost 



• of ambulator) legs have the tubercle on the fourth joint, already represented by Sars; but it is 



lable that these two characters may be found also in Ascorhynchus abyssi. Finally 



the ratio of length between the joints of the palps is not a little different from that in the species 



The differing structure of the chela and its fingers is scarcely to be regarded as a specific
