In accordance with this representation I would place Monascus

Anatomy. — "On the genital cords of Phalangista vuljnna." By 

 Mr. A. J. P. VAN DEN Beoek. (Communicated by Prof. L. Bolk). 

 (Communicated in the meeting of May 28, 1904.) 



In the course of an investigation concerning the structure and 

 development of the female genital organs of marsupials, the result 

 of which will be more extensively published elsewhere, 1 had an 

 opportunity of studying a series of transverse sections through a young 

 female specimen taken from the marsupium of Phalangista vulpina, 

 measuring 16.7 mm. 



An examination of the genital cords and of the Wolffian and 

 Müllerian ducts enclosed in them, revealed a relation differing 

 from what is noticed in the genital cords and the above-mentioned 

 ducts both in Monotremes and in monodelphic mammals and which 

 appears to be connected with the peculiar anatomical details of the 

 genital system of the marsupials. 



In following up the genital cords, after they have issued from 



the tissue of the primitive kidney, in a 

 caudal direction, it is noticed that the 

 \ tt /// y- cords from both sides approach each 



-^ rEEi^'f /4^7 other, unite into a single cord along a 



\i\ 1 1 ' ^^^^^"^ distance, then separate again and 



U /|[_ /__ r//; are continued in a caudo-lateral direction 



l^f-f^l \ I as far as the wall of the uro-geni(aI 



\dh\Jl \l sinus. In this manner a short bridge is 



formed, connecting the two genital cords. 

 On reconstructing the successive cross- 

 sections, we obtain w^hat is schematically 

 represented in fig. 1, where the genital 

 apparatus is represented as seen from
