genital passage, a very minute transverse slit lined by epithelium, 

 quite away from the aperture of the median vaginal prolongation. 

 In the first two sections in which it appears the transverse slit is 

 rather indistinct and all efforts with the high power to trace 

 it in preceding sections have failed. In the eighth section after 

 its first appearance it opens by a narrow duct into the urogenital 

 passage. 



In the other specimen the same condition as has been described 

 in 0. robicstics No. (c,) was met with. That is the cavity of the 

 mesial cul-de-sac gradually diminished in size and finally dis- 

 appeared, and in the forty-second section after this the urethra 

 entered the urogenital canal. 



How to account for the difference between these two specimens, 

 otherwise so much alike I do not know. In the first of the two 

 there is certainly no direct communication. If there had been 

 any signs of pregnancy the condition met with would have been 

 perhaps more intelligible. As it is I refrain at present from 

 making any further remarks in the hope of shortly having further 

 opportunities of investigating this point. 



In conclusion I have to thank my friends Messrs. Baker, 

 Morley, and Webb for assistance in getting specimens and in 

 other ways. I have also to thank Mr. Ramsay, F.L.S., of the 

 Museum for his kind help in determining the species to which 

 one of my specimens belonged. 



Description of two new species of Snakes. 



By the Hon. William Macleay, F.L.S. 



In the following paper I give the descriptions of two Snakes 

 recently sent to Mr. E. P. Eamsay by his brother Mr. James 

 Ramsay, both specimens taken on his station near Fort Bourke. 



The first is one of the very venomous Family of ElapidcB, and 

 is so distinct in many respects from all of the genus Diemenia
