886 ANATOMY AND DKVELOPMENT OF MARSUPIALIA, 



the presence of distinct era separating the uterine and vaginal 

 segments of the Miillerian ducts, and an elongated urogenitali 

 sinus are points in which the genital organs of Sarcophilus are 

 relatively more advanced than those of Pe^-ameles. At present, 

 I will content myself, for tlie purposes of this paper, with merelj'- 

 briefly pointing out above these points, reserving discussion, at 

 a greater length, for the future, when a larger number of speci- 

 mens have been examined.
