HANSEN AND SÖRENSEN, THE TARTARIDES. 71 



Explanation of the Plates. 



The figures of first leg together with the palp and of the 

 fourth leg not only of the same animal bnt of adult specimens 

 of both sexes of the same species, ha ve been drawn with the 

 same degree of enlargement. — At least one of the figures, 

 and sometimes both figures, of the flagellum in the male and 

 the figure of the female flagellum of the same species have 

 been drawn with the same degree of enlargement (but this 

 degree is, of course, higher than that of the legs). — In most 

 cases the two tactile hairs at the end of tibia of first leg have 

 been omitted; on the figures of fourth leg and of the foot of 

 first leg the setse are nearly always omitted.
