The lateral canals pass at lirst directly outward from a point rather 

 anterior to the uterine orifices ; they then turrt sharply backward, and 

 after a long even course terminate as usual in the urogenital canal. 

 The chief peculiarity of the lateral canals is that there is no thicken- 

 ing of the muscular walls at any point, and no contraction and no cross 

 fold ; the canal pursues an uninterrupted course. 



In his paper (already cited) Brass describes a specimen of the genus 

 Hypsiprymnus (species not given) which had a large bladder-like 

 prolongation forward of the region, common to the median and lateral 

 canals. The median canal is moreover represented as terminating 

 some distance from the urogenital chamber. In both these points 

 our specimen differs from his. His figure shows the clear passage 

 down the lateral canal, with uo muscular thickening and no con- 

 striction, very distinctly. 



In the following Table the condition of the median canal in the 

 foregoing examples is stated, and also the fact, where it has been 

 ascertained, as to whether young have been born. 



' It is possible that these two are identical with tlie '• Kangaroos " quoted 

 above. 



- We are informed by Mr. Forbes that this animal is properly a Pcirogak.
