PlOTOBIAL GbOUPS. 



Among the Picfcoral Groups of Birds mounted during the past year, 

 the most notable are the Penguins. These birds represent in the 

 Southern Ocean the Auks and Divers of the Northern Seas of which 

 groups have been previously prepared. Being adapted in the highest 

 degree to a life in the water the Penguins represent among birds the 

 Seals among Mammals with many corresponding adaptations. These 

 are shown as far as circumstances permit in the arrangement of the 

 specimens and groups, which illustrate all the principal forms and most 

 of the known species.
