496 LILIAN SHELDON. 



In none of the legs of Peripatus novse zealandiae, of 

 which I examined sections, did I find any crural glands, either 

 in the male or female. I took legs from the various parts of 

 the body in both sexes, and in all cases the segmental organs 

 were present, and the legs contained a much larger supply 

 of muscles than those of P. capensis, but there were no 

 traces of crural glands in any case, even in the last leg of the 

 male. 



In P. Edwardsii Gaffron (2) states that the crural glands 

 are absent in the female, but are present in some of the 

 segments of the male; therie being in some of them two 

 pairs. 



Segmental Organs. 



In Peripatus novse zealandiae the external aperture 

 of the generative apparatus is placed on the ventral surface of 

 the body in front of the, last (fifteenth) pair of legs. In this 

 pair of legs there are no segmental organs, so that the genera- 

 tive ducts are apparently the modified segmental organs of the 

 last segment. 



In Peripatus capensis, in which the generative aperture 

 is situated at the posterior end 6f the body, immediately in 

 front of the anus and behind tihe last pair of legs, segmental 

 organs are present in the latter. 



In P. nova zealandise, as was described in P. capensis 

 by Professor Balfour (1), the segmental organs of the fourth 

 and fifth pair of legs are much larger than the rest. 



Accessory Glands of the Male. 



In P. capensis, in addition to the enlarged crural glands 

 of the last pair of legs, the ruale generative apparatus is 

 provided with a pair of glandular tubes, which lie on each 

 side, and dorsally to the ductus ejaculatorius, into which they 

 open at the point where it opens to the exterior. These 

 accessory glands were first mentioned by Professor Moseley (4),
