in the vasa eflferentia, the kidney or ureter. I have, however, 

 no doubt as to the connection of the branches of the Vasa 

 efferentia with the Malpighian capsules as alcove described. 

 [Cf. PI. XX., fig. 1.] 



Noiadi'N hoinetli. 



In the male specimens of this species available, the testes 

 were spherical bodies having about the same diameter as the 

 kidney itself, but quite unsymmetricall}' placed — the one at 

 about the middle of the length of its kidney, the other at ihe 

 posterior end of its kidney — each lying laterally to the kidney 

 of its own side, the mark * [in PI. XX., (ig. 2] indicating the 

 inner edge of the testis lying in the mesorchium. As stated in 

 Part I. A., the ureter lies often in the peritoneum lateral to 

 the kidney, and often, near the hinder end of the kidney and 

 posterior to this, it swells out to form a large glandular Vesi- 

 cula seminalis. The Vasa efferent ia. pass in along the mesor- 

 chium, and entering the kidney run straight out to open into 

 the Bowman's capsules of the Malpighian bodies in the inner 

 one-third (if the kidney. I have lieen unable to find any 

 longitudinal Bidder's canal. 



Chiroleptes alboguttatus. 



In this form the testes are long and thin, and in the speci- 

 mens examined very feebly developed, i)robably owing to the 

 season of the ^^ear. Tbey were approximately one-half the 

 length of the kidney and one-third its average width. The 

 Vasa efferentia pass into the kidney at its inner edge from the 

 inner side of the testis as usual, and spread out at unce into 

 the kidney substance without forming any longitudinal canal. 

 Apparently they enter the ventral part of Bowman's ca[)sule, as 

 in previous forms. Owing to the extreme vascularity of the 

 kidiiey and the great number of corpuscles present in all the 

 blood--spaces, it is difficult to make out the relationship of these 

 ducts further than as indicated al)Ove. 



Heleioporns pictus. 



The testes of H. pictus are very irregular in shape, and 

 unequally develoijed on each side — that on the one side being
