tibia longer than its patella, about twice as long as broad, 

 but shorter than the tarsus, armed at its distal end externally 

 with a stout process ; palpal organ as in figure (PI. XIX. 

 fig. 7). 



Legs long and slender, 1 and 4, 2, 3, strongly spined ; tibia 

 of first and second with spines above. 



Measurements in millimetres. — Total length 11'5; length 

 of carapace 5, width 4*2 ; length of palp 6, of first leg 22, of 

 second 21, of third 18, of fourth 22.

Apparently resembling I), flaminius and D. facetus of 

 L. Koch in many structural features, but certainly differing 

 from both in the form of its palpus. The greater width of 

 the carapace as compared with its length forbids the view 

 that the species is the male of the one I have identified as 

 D. icadiuSy unless such a sexual difference is found to obtain 

 in other species of the genus. In the female referred to 

 icadius the length of the carapace is 7 and the width 5'5.
