There are also many iiisiguificaut longitudinal folds, but without 

 any very definite arrangement. 



On comparing the urogenital organs of this species with those 

 of O. rohushis they agree in the following particulars: (1) in 

 having a post partum direct communication between the median 

 vaginal and the urogenital chambers, and in not having it before 

 parturition so far as we know at present ; (2) in having the lateral 

 canals developed to about the same extent ; (3) in having the 

 urogenital canal, fully 2 in. or more long in average specimens ; 

 (4) and in having correspondingly long and conspicuous ridges 

 on the veutral surface of that canal. In addition they agree 

 essentially in other particulars not now under consideration, and 

 as far as I can see they do not differ materially from one another 

 in any single important particular. 



On p. 02 of the article Marsupialia, Professor Owen says " It 

 is not unusual to find the vaginsB of the Kangaroo distended with 

 a gelatino-mucous adhesive secretion containing hard irregularly 

 shaped fibrous masses. One of these bodies which was found in 

 the mesial cul-de-sac of a Kangaroo was described and figured 

 by Home as the vertebral column and occipital bone of a foetus 

 * # * # Professor Leuckhart who found similar bodies in 

 the vaginal tube of a Kangaroo, compares them to a mola or false 

 conception, but observes that there was nothing in their structure 

 that would permit him to form a conclusion that they were parts 

 of a foetus." Again on p. 63, the same distinguished author 

 speaks of the " inspissated secretion commonly present both in 

 the cul-de-sac and the lateral canals." Other observers have 

 described similar finds. In one of my specimens of O. rufus the 

 anterior portion of the median vagina was much distended, and 

 this was found to be due to the presence of two yellowish resinous- 

 looking masses of irregular shape, which extended someway into, 

 and completely blocked the lateral canals. There was a third 

 similar but smaller fragment between the other two. In a
