422 Baldivifi Spencer: Neiv Species of Per ijxUo ides. 



Crural Glands. — In one of the four specimens each of the 

 legs, 6-14, carries a definite, small white glandular patch placed 

 on the distal side of the nephridial opening, and always sepa- 

 rated from the latter by two rings of papillae. These, presum- 

 ably, indicate the openings of crural glands, but I can see no 

 trace of them on the two last pairs of legs, nor in the region of 

 the reproductive opening. Their presence indicates the fact that 

 this one specimen is a male and the three others females. In 

 the latter there is no trace of any ovipositor, and in both males 

 and females the generative opening lies between the base of the 

 last pair of legs. 



Jaws. — The first jaw is simple in all the specimens, there 

 being no trace of any accessory tooth. The second jaw has four 

 clearly-marked and one minute accessory tooth. 



The number of the legs, together with the structure of the 

 jaws, serves to distinguish this species from all other Austral- 

 asian species of either of the genera, Peripatoides or Ooperi- 

 patus. 



Locality. — Armadale, near Perth, West Australia. Collected 

 by Mr. H. M. Giles.
