Remarks. Only two of the species recorded above show any marked deviation from previous re- 

 cords of their distribution. Both Dactylambylops hodgsoni and Euchaetomera zurstrasseni are Antarctic 

 forms or from very far south in the South Atlantic. Their capture off the west coast of South Africa 

 is considerably farther north in the Atlantic than any previous records of them, although E. zurstrasseni 

 was originally taken in the Indian Ocean to the west of Chagos Islands.
