the same species, placing it with two others which were really 

 new to science, in a new genus, Ophiocamptus, thus showing that 

 he also recognised the necessity of separating Sars's C. brevipes 

 -and closely allied forms from the old genus C anthocamptus (4). 



The characteristics of the genus Moraria are chiefly as 

 follows : Body very elongated, almost vermiform. Rostrum 

 broad. First antennae seven-jointed. First four pairs of feet 

 with three-jointed outer and two-jointed inner branches. Inner 

 branches of first pair of feet only a little shorter than the outer 

 branches, with the basal rather longer than the terminal joint. 

 Inner branches of the second, third, and fourth pairs of feet 

 only a little longer than the first joint, or at most only as long 

 as the first two joints of the outer branches. Furca well de- 

 veloped, each branch tapering considerably from base to tip, and 

 usually (? always) furnished with a strong longitudinal chitinous 

 ridge on the dorsal surface. 



So far as I can ascertain, eight species of Moraria have hitherto 

 been described and two others referred to, but not described. 

 They are as follows : 



M. brevipes (G. 0. Sars), 1863 = C anthocamptus brevipes G. 0. 

 Sars, 1863 (11); M. anderson-smithi T. and A. Scott, 

 1893 (14) ; Ophiocamptus sarsi Mrazek, 1893 (4). 



M. mrdzeki T. Scott, 1903 (13), new name only = Ophio- 

 camptus brevipes Mrazek, 1893 (4). 



M. poppei (Mrazek), 1893 (4) = 0. poppei Mrazek, 1893 (4). 



M. muscicola (Richters), 1900 (9) = 0. muscicola Richters, 

 1900 (9). 



M. schmeili van Douwe, 1903 (3). 



M. mongolica (Daday), 1906 (1 and 2) = 0. mongolicus Daday, 

 1906 (1 and 2). 



M. wolfi Richters, 1907 (10). 



M. quadrispinosa Richters, 1907 (10). 



M. sp. 1 Richters, 1907 (10). 



M. sp. 2 Richters, 1907 (10). 



Most, if not all, of the above have been found living in wet 

 -or damp mosses ; some, in fact, have hitherto been found in no 

 other situations. Only the first three have been found in the 

 British Isles.
