PARASTENHELIA. 119 



The mandibles resemble those of Stenhelia ; the basal joint 

 of the mandible-palp, which appears to be club-shaped, ex- 

 pands towards the distal end and bears two small uniarticulate 

 branches, tbe distal branch being more elongated than the 

 other (PI. X. fig. 11). 



The second maxillipeds are somewhat similar to those of 

 Stenhelia Mttpida, G. S. Brady, but there appears to be a 

 slight difference in the armature of the second joint and in 

 the length of the terminal claw (PI. XIII. fig. 9). 



The first pair of thoracic feet have the inner branches 

 three-jointed and very slender and elongated, being equal to 

 about twice the entire length of the three-jointed outer 

 branches ; the first joint about half as long as the second, but 

 the end joint is small; a plumose seta springs from the inner 

 distal angle of the first joint, while the end joint is provided 

 with two terminal claw-like spines of unequal length. The 

 outer branches, which reach to about the middle of the inner 

 ones, are moderately stout, the end joint is much smaller than 

 the first or second, which are subequal; the armature of the 

 outer branches is somewhat similar to that of the same 

 branches in Stenhelia iiua (PL XVI. fig. 4). 



The next three pairs are slender and moderately elongated. 

 The fourth pair, which are represented by the drawing (PL XIV. 

 fig. G), have the outer branches about a third longer than the 

 inner ones ; the first and second joints are each furnished with 

 a small spine near the distal end of the outer margin and 

 with a plumose seta on the inner margin, while two spines, 

 one small and one long and slender, and also a moderately 

 long seta, spring from the extremity of the third joint. The 

 first and second joints of the inner branches have each a seta 

 on the inner margin, but the end joint is provided with two 

 setre on the inner margin and with a small spine and two 

 setre at the apex, as shown in the drawing already referred to. 



The fifth pair have a small primary (or basal) joint which 

 is of a subtriangular form and bears five setre on the lower 

 half of the inner margin and apex. The secondary joint is 

 elongated and subcylindrical, but the distal half of the outer 

 edge slopes gradually to the narrow extremity; the inner 

 margin, on the other hand, is nearly straight from base to 

 apex ; a single seta springs from near the lower end of the 

 inner margin and five from the outer margin and apex, as 

 shown in the drawing (PL XVII. fig. 4).
