ACARI 555 



The claws are very slender and inconspicuous, hidden, as 

 they are, in the enormously developed caruncles. I hâve been 

 nnable to ascertain the exact shape of the hitter, as they were 

 folded up in the spécimens in my possession. 



Legs II (fig. 59) differ in the following respects from M. 's 

 spécimens : on calcar f emoralis the terminal tooth is not 

 bifid, but truncated, and between the large pilus axillaris 

 and its subterminal tooth there is another, low, rounded tooth. 



Processus genualis is comparatively longer, but of the 

 same shapè ; it is not sessile, but in the middle of it we notice 

 a distinct transverse fissure, nor is processus tibialis sessile, 

 but near its base there is an obliquely transverse fissure. 



Telotarsus has ventrally, beliind the middle, a very stout, 

 sharply pointed bristle, pointing straight forward, paraUel 

 to the ventral edge of the tarsus ; in M. 's spécimen it is inser- 

 ted in front of the middle. 



The ambulacres of legs II are difïerently shaped to those 

 of the nympha (fig. 60) ; the claws seem to be stronger and the 

 subunguinal caruncle is finely fringed, contrary to what 

 is the case in the nympha. O^ving to its not being unfolded I 

 hâve not been able to ascertain its exact shape.
