 Stns 1370, 1568, 1569 and 1762 are south-east of Africa, all the other localities are off the west coast of Africa. 

 St. WS 657 is on the Pacific coast of Peru, the other localities are off the southernmost part of the coast of Patagonia. 



In all the specimens the tentacle bulbs have the broad base with an abaxial keel clasping the edge 

 of the umbrella margin, which is characteristic of A. macrodactyla in contradistinction to A. pensilis, 

 and numerically they correspond well with the specimens from the Great Barrier Reef previously 

 examined by me. The specimen from the East Pacific, St. WS 657, has a comparatively small number 

 of radial canals : 46 radial canals, 1 5 tentacles and about 30 young bulbs. The following table gives the 

 dimensions of the specimens taken in the Atlantic and south-east of Africa. Those from South America 

 are marked with an asterisk ; these differ in no essential way from the specimens taken off the coasts of 

 Africa.
