altogether unexplored; and who can say what it may bring to light, 

 when systematically worked, that will prove of value and interest 

 to the biologist ■? 



Now that these South Pacific Islands have been brought under 

 the British flag, it may not be out of place here to suggest that a 

 more appropriate or distinctive name be chosen. This would 

 have many advantages; in the first place it would remove the 

 confusion that at pi'esent exists when the name of Santa Cruz is 

 mentioned. On referring to an atlas it will be seen that there 

 are three large islands bearing this name : one off the coast of Cali- 

 fornia, a second in the West Indies (Caribbean Sea), and a third 

 the island and archipelago in the South Pacific. The name Santa 

 Cruz, has been indiscriminately bestowed upon numerous occasions, 

 having been used for towns, mountains, rivers, islands and an 

 archipelago. In respect of the island under consideration, 

 Nitendi was the old native name.
