 (Plate XXIT.) 



The specimens which form the subject of the present supple- 

 mentary note upon tbe fauna of the Mergui Archipelago, were 

 unfortunately overlooked when Dr. Anderson's collection was 

 originally distributed to the various specialists who have reported 

 upon it. 



These specimens were contained in two bottles — one being 

 ticketed Mergui, the other Owen's Island. Something of intei'est 

 was found in each bottle — two of the Myriopoda from Owen's 

 Island proving to be new species, while several examples of 

 a large Tetrapneumonous spider from Mergui appear to be 

 representatives of a new genus.

Dr. Anderson obtained this species at Mergui. It is widely 

 distributed in Further India and the Malay Archipelago, having 

 been recorded from many localities between Bengal and Singapore.
