it becomes a tall shrub, and forms submaritime thickets, which har- 

 monize with the natural vegetation ; and although the only known 

 example of the family in the New Zealand flora, it appears to be 

 really indigenous. 



b. Animals and Plants of European Introduction. 



Within the past century, and for the most part within the memory 

 of persons now living, a variety of animals and plants, have been in- 

 troduced into the islands of the Pacific in European and American 

 vessels : 



The bullock, was carried from Taheiti to the Samoan and Feejee 

 Groups, a short time prior to our visit. At the Hawaiian Islands, 

 the animal has run wild for many years on the upper portion of 

 Mauna Kea. 



The horse, has been introduced into Taheiti, Samoa, and the Hawa-

 Feejee Group. 



The goat, has run wild at Taheiti, at the Hawaiian Islands, and at 

 Ovolau in the Feejee Group; and it has recently been carried to 

 Samoa. 



The sheep, seems to have become permanently established at the Ha-

The cat, was seen at Taheiti, and at Tongataboo. It has run wild

 markable bird, allied to the ground-dove." 



The mouse, occurs on those islands which have been most frequented

The turkey, is now abundant at the Hawaiian Islands.

The common duck, has been introduced into Samoa; and likewise,

The domestic ^^^eo^^, has been introduced into Taheiti, and into the
