 conditions in which it seemed certain that it was a hybrid 

 between a male Thrush [Turdus musicus) and a female Black- 

 bird {Merula merula). 



Mr. L. A. Borradaile, M.A., F.Z.S., presented his memoir 

 " On the Structure and Function of the Mouth-parts of the 

 Pala^monid Prawns," and explained his conclusions by means of 

 blackboard drawings, and also demonstrated the method of taking 

 food, by means of living examples of prawns. 



The Author regards the primitive crustacean limb as consisting 

 of a flattened axis with a fiabellum (exopodite), two or more 

 epipodites, a series of eight endites, and an apical lobe, the 

 fiabellum standing opposite the third and fourth endites. He 

 discussed the relation of the several jaws to this prototype.
