Prof. F. Jeffrey Bell, F.Z.S., called attention to the acquisition 

 by the Natural History Museum of some specimens of remarkable 

 Corals of great size from North-west Australia, of which he 

 showed some admirable photographs taken by Mr. Percy Highley. 

 Prof. Bell urged the necessity of the acquisition of large specimens 

 of Corals, before coming to any conclusion as to their specific 

 distinctions.

1. On some Points in the Anatomy of Ornithorhynchus 

 paradoxus. By T. Manners-Smith, B.A. (Cantab.),

 College, Birmingham. 



[Keceived October 30, 1894.] 



The following is a series of notes upon certain points in the 

 anatomy of Ornithorhynchus paradoxus. Though the muscular 

 system of this animal has been frequently described, e. y., by 

 Meckel *, Owen 2 , and more recently by Coues r) , it has occurred to 

 me that there is room for a description of the muscles of the 

 limbs, together with the nerve-supply in those cases where such 

 supply is peculiar, wholly or partially, to the animal under 

 examination. 



The work of Coues was undertaken without reference to Meckel's 

 memoir, and Coues differs, in some particulars, from the description 

 of the muscles as given by Owen. 



In view of these circumstances, and considering the development
