over the important part which the bladder and the urethra play in 

 bringing about this relation, must not be left out of consideration. 

 The meatus urinarius is situated on the ventral wall of the uro- 

 genital chamber at about i in. from the anterior end of the 

 latter, consequently the tissue of the urethral wall must be con- 

 tinuous with that of the urogenital canal. Similarly the tissue 

 of the cervix of the bladder fuses w ith that of the wall of the cul- 

 de-sac at about l in. from its end, and the urethra has the 

 appearance of being buried in the wall of the cul-de-sac. Hence 

 throughout its course, the urethra is fused with the wall of the 

 cul-de-sac on the one hand, and with the wall of the urogenital 

 passage on the other, and so helps to bring these parts into very 

 close relation. This is the arrangement which Brass figures in 

 Hypsiprymnus, and JEL. hennetti, while in his figure of M. major the 

 arrangement is quite different. Possibly Prof. Owen's specimen 

 was like this too : in which case these two specimens, as it seems 

 to me, can be regarded only as interesting and remarkable varia- 

 tions from the more typical arrangement which I have met wdth 

 in a larger number of examples, and w^hich obtains in other 

 species. 



Ojs- a species of Beachtphtllum: feom Mesozoic Coal 

 Beds, Ipswich, Queexsla^-d. 



By the Eey. J. E. Tenisox-Woods, F.L.S., &c. 

 A very interesting discovery has been lately made at the 

 Tivoli Mine, Ipswich, Queensland. The coal beds there have 

 yielded a specimen of BracliypliyUim, closely allied to the well- 

 known and common Oolitic B. mammillare, Brongt. It is associated 

 with Tceniopteris, Alethopteris australis, Equisetum rotiferum 

 (nobis), Tliinnfeldia adonfopteroides Splienopteris eJongata, etc. 

 It was brought to me by Mr. Meston, who was then the proprietor 

 of the mines, and was found amongst the shale in the workings 

 immediately above the coal seam in somewhat impure coal.
