Lipura greenlandica, Tullb. (7). 
Several specimens of this species were found at Cape Flora 
(19th August, 1896; 9th, 14th, and 19th July, 1897). Its presence 
in Franz-Josef Land might have been expected since it occurs 
both in Greenland (7) and in Spitzbergen (2, 7). Its structural 
features are clearly figured by Tullberg, and the presence of only 
a single prominence in each post-antennal organ makes its 
identification easy. 
Achorutes dubius, Tullb., var. concolor, nov. 
Numerous examples of this springtail were found at Cape 
Flora (19th August, 1896), at Cape Gertrude (27th June, 1896),
