upper lobe (L'jaiid a more or less truncate lower one (L^). For comparison we figure 

 these organs of an Hungarian example and of an (tgi/rtes from Borkuni (the 

 original locality of agyrtes). It will be noticed that in true agi/rtes (text- 

 fig. 2) the lobe L-' is obsolescent, while it is well produced in all examples of 

 eiiroKS. There is some variability in the length of L' and L- in fnioux, bnt the 

 sinns between them is never so deep as in jnoeinciidix. 



?. The seventh abdominal sternite is deeply and broadly sinuate vent rally, 

 there being one large lateral lobe, which is broader than in ayi/rfe.t. There is no 

 narrow lobe beneath this broad one. The eighth tergite has vcntrally a row 

 of five bristles as in agi/rtes, the last one being short, and above this row one 

 long bristle accompanied by one, two, or rarely three small ones. 



C. agyrtes has not previously been recorded from Hungary.

 fig. 24, tab. 10. fig. 29 (1898), described from 2 cJcJand 1 ? found on Putorius 

 vulgaris at New Alexandria. The occurrence of uncinata on Putorius we believe to 

 be accidental, the true host probably being Microtus, as in the case of obtusus. As we 

 have no example of uiwi/iuta in the collection, we rely on Wagner's figures, wiiich 

 represent the claspers of the <J and the head, and tlierefore restrict our descrijition 

 to the modified abdominal segments, whose structure affords the best and perhaps 

 the only distinguishing characters. Tiie cliaetotaxy of the body and legs in 

 uncinata according to Wagner is the same as in C assimilis Tasch. (188U), but 

 diflers appreciably in obtusus, especially in the ? . 



c?. The clasper (CI) agrees perfectly with the figure given by Wagmr of that 

 sclerite of C. uncinata, the nose-like process varying a little individually, being 

 sometimes more rounded, sometimes more jwinted. The movable process (F) is 

 more than twice as long as it is broad in obtusus, whereas it is only half as long 

 again as it is broad in Wagner's figure of uncinata ; its proximal margin is incurved, 

 not straight, the upper margin also being distinctly excised. The upper distal 

 corner, which is produced into a hook in uncinata, i)ri)jects very little in the new 

 species. But there is on the inner surface of F just below the corner a groove
