During the year the Zoological Park received from abroad 

 many important accessions of mammals, birds and reptiles. 

 Besides receipts from miscellaneous sources, three large collec- 

 tions arrived from England, South Africa and Australia. These 

 important accessions had the effect of filling nearly all the hith- 

 erto empty cages at the Zoological Park. Full statements re- 

 garding these accessions will appear in the Zoological Society 

 Bnlletin and in the report of the Director of the Zoological Park 

 in this volume.

Compared with January 1, 1920, this census shows an in- 

 crease of twelve species and 2,660 specimens. 



Plans for the alterations of the Aquarium, by transferring 

 the boilers to the front of the building, are approaching com- 

 pletion. 



The emergency repairs to the roof of the Aquarium and to 

 the boilers have been completed and will be paid for by the City. 



During the year, eleven of the glass-fronted exhibition 

 tanks on the main floor of the Aquarium were enlarged by the 

 Society at a cost of $2,440, thus completing this important im- 

 provement of the main floor tanks. 



The well-boat Seahorse, built and equipped by the Society 

 at a cost of $4,334.25, was in service about two days a week 

 from May 29 to November 8, 1920. The boat made twenty-six 

 trips, collecting over 3,000 fishes of sixty different species, be- 

 sides many invertebrates, useful both as exhibits and as fish food.
