The Secretary, on the part of Dr. Falconer, exhibited the lover 

 end of the left tibia of a gigantic fossil Struthious Bird from the Se-

 representation of the existing African Struthio in the extinct fauna 

 of Asia. Although not altogether unexpected, this is a valuable addi- 

 tion to the facts previously demonstrated in relation to the genera 

 Camelopar dalis, Camelus, Elephas, and Hippopotamus . 



The Secretary also announced to the Meeting that a living speci- 

 men of Otocyon Lalandii, a drawing of ^vhich was exhibited, had
