United States Exploring Expedition. 



403 



insessorial species were found to be confined to a single island. 

 About fifty new species were obtained. 



The field for mammalia afforded by the voyage has been very 

 limited. None of the Pacific islands, including New Zealand, 

 contain any native mammalia, except bats. Much interesting 

 information was however obtained relative to species met with on 

 the continents visited, and a few new species were collected. 



The following is a list of the number of species in the other 

 departments of zoology, as nearly as can now be determined :
