passing down over the anterior end of the female, came to lie 

 beneath her, the animals being now headed in opposite direc- 

 tions and with their ventral surfaces opposed. The basal 

 joints of the legs of the female were approximated below, with 

 the mass of eggs between them. As the male came around 

 below the female, the ovigerous legs, which are curved at the 

 ends, forming a sort of hook (Fig. 5), fastened into the egg-

masses, and as the 

 animals separated 

 pulled the eggs away 

 with them. The 

 masses did not pull 

 away clean, but 

 strung out more or 

 less, leaving a very 

 few eggs still on the 

 female. For some 

 time after they sep- 

 arated the male was observed to work the ovigerous legs slowly, 

 the effect seeming to be to get the eggs more firmly upon them 

 and into a more compact shape. The time from when the 

 animals were first observed until they had separated was only 

 about five minutes. 



Some of the males have but one egg-mass on the ovigerous legs, 

 but more often there are two, as shown in Fig. 4. I am unable 

 to say with certainty whether this means that the male takes 

 the eggs from two females or that he gets them in two masses 

 from one; but from the fact that in those cases in which they 

 were examined the eggs in the two masses appeared to be in 

 the same stages of development, I am inclined to the latter 

 view. The genital openings are situated on the ventral side of 

 the second joint of all four pairs of legs, and it is easy to see 

 how the eggs of one female might gather into more than one 

 mass.
