The type of Sesarmaxenos nionticola was taken by Mr. B. B. 

 Osmaston in January, 1907, and was attached to the ventral 

 surface of the carapace of a female (one of the types) of Sesarma 

 thelxinoe de Man, which was found about 700 feet above the sea in 

 a stream running through thick jungle on Mt. Harriet near Port 

 Blair in the Andamans. I have searched through the whole of the 

 collection of Grapsidae in the Indian Museum without finding 

 another specimen of this or of any other Rhizocephalon.
