examined by me the elevation from which the mesial anterior 

 sarcotheca springs is decidedly more pronounced than in Kirchen- 

 pauer's and Allman's figures.

 Having had the opportunity of examining fertile specimens of 

 Jj. urens from Moreton Bay I have now no doubt as to their 

 specific identity with Z-.. j^hillipinus. Ihe slight difference in the 

 form of the hydrothecae indicated by Kirchenpauer is inconstant, 

 Tx)th forms having lateral lobes which often tend to become obso- 

 lete. The gonangia are described as large in L. phtUipi7iu.^ and 

 unusually small in L. urens, a difference which appears to be 

 merely sexual, L. phiUipliias l)eing the female form and />. urens 

 tlie male.
