paratively liaimless from this point of view, that it did not

The motion was carried unanimously, 



Mr. Lucas then read a paper entitled " Fishes new to 

 Victoria not hitherto described." 



The President said it was satisfactory to see the Biologi- 

 cal Exploration of Port Phillip progressing, new specimens 

 being obtained and new species named. 



Mr. McAlpine, vefemng to the peculiar marks by which 

 the sexes could be distinguished in the species described by 

 Mr. Lucas, said that this was an exception to the general 

 rule. It would have been of great service to him had he 

 been al)le to distinguish between the sexes of the cod when

 He thought it very desirable that, in the case of the food 

 fish, some means of distinguishing the sexes should be 

 discovered.

 the case of a few other species with coloured fins, a distinction 

 could sometimes be made. 



Professor Spkncer read a paper entitled " The Nomen- 

 clature of Chicken Embryos." At its conclusion, some 

 lithographed illustrations were passed round. 



The President said he thought Professor Spencer's 

 suggestions very reasonable. 



Mr. McAlpine said he thought the proposal an excellent 

 one, and would be a very desirable innovation from a 

 student's point of view. Under the old hours system, great 

 difficulty was experienced in determining the stage at which 

 the embryo had arrived. 



Mr Dendy then read a paper "On the Victorian Land 

 Planarians." 



The President remarked that Mr. Dendy had followed 

 up this subject with great vigour and perseverance. 



Mr. Hogg said that Mr. Dendy 's paper was so exhaustive 

 that little could be added. He had lived in a place where 

 planarians were very numerous and had been able to see
