The occurrence of the recently described Aegean orientalis 

 Henderson, from the litoral of the Burmese coast (Gulf of Marta- 

 bem) is remarkable, because this species is said to be related to the 

 Mediterranean Pontophilus cataphraebus. It may, however, belong 

 to the genus Pontecaris, and the description and figure given by 

 Henderson do not refute this supposition.
