The present specimen must he considered the type of a new species; it is very closely allied to .1. com- mcnsalis Bonnier (1896, p. 614, PI. 35 rig. 4), but it differs in the total want of eyes, the different shape of p. 2, the great process on the hind edges of the coxal plates of p. 5—p. 6, and other characters. The specific n falcatus (it is: scythe-shaped) is an allusion to the process on the coxal plate of p. 6 (similar processes, hut not epiite so highly developed, are also found by investigation of material of .1. tumidus ami .1. ncglcctus in the Copenhagen Museum, hut they are not to he seen in Sars's figures [Sars 1895]).
