Thiele der beiden Vaginae, in der Mittellinie eng vereinigt, bis 

 hinab zum Sinus urogenitalis ohne denselben einzumunden." 

 From the median vaginae there pass off anteriorly and ventrally 

 the vaginal canals. The morphologically anterior portions of 

 these have essentially the same relations as the corresponding 

 parts in Perameles — i.e., they run directly forwards parallel with 

 each other, in the connective tissue just ventral to the uterine 

 necks (fig. 2, a.vag.c ). About the middle of the extent of the 

 latter, the two canals leave the connective tissue mass and bend 

 outwards at right angles to their former longitudinal course to 

 form free tubes which, as Leche notes, are of considei'able length 

 and characteristically coiled (fig. 1, l.vag.c). After forming one 

 or two turns on each side the vaginal canals again pass inwards 

 towards the median line and just behind the median vaginae come 

 to lie parallel with each other and with the urethra. The three 

 canals are imbedded in a longitudinal strand of connective tissue 

 (fig. 3, l.vag.c, ureth.), representing the urogenital strand of 

 Perameles, and as in that form the part of the tissue between the 

 vaginal canals lies in the direct continuation of the median vaginae. 

 After a short course (about 3 mm.) in the same, the two vaginal 

 canals and the urethra all open by separate apertures at the same 

 level into the urogenital sinus. 



The urogenital sinus is, unlike that of Perameles, a long narrow 

 canal, having in this small female an approximate length of about 

 15 mm. 



As Leche has pointed out, a distinct cloaca is present, into 

 which the rectum opens dorsally and the urogenital sinus ven- 

 trally. A pair of large "anal glands" are situated dorso-laterally 

 in the circular cloacal musculature (fig. 1, a.g.), and open by fine 

 ducts just within the margin of the cloacal opening. There are 

 also present in the wall of the cloaca, as in Perameles, numbers 

 of tubular glands which open partly into the ducts of the anal 

 glands and partly directly into the cloaca. 



The clitoris in my specimen is attached throughout its length, 

 and, as Leche notes, is simple. Apically it is divided into two 

 united halves by a septum.
