Physophora hydrostatica Forskal, 1775. 



This almost cosmopolitan species, which is especially common in the North Atlantic Gulf Stream 

 area and the Mediterranean, has been shown by Kramp (1942) not to occur in the cold tracts of the 

 Polar Currents. So far the only Indian Ocean record is that of Haeckel (1888 b) from off Ceylon. There 

 are records from the Malaysian region by Lens & van Riemsdijk (1908); off South Australia (43 ° 26' S., 

 126 37' E.), by Huxley (1859); the North-eastern Pacific, Bigelow (191 ib, 193 1) — I have examined 

 young specimens from La Jolla, California — and North-western Pacific, Bigelow (1913). Bigelow 

 (1931) pointed out that it had not been recorded from as high latitudes in the Pacific as in the Atlantic. 

 From the South Pacific (Station 967) 'Discovery II ' took this species midway between New Zealand 

 and South America at a temperature of 9-5° C, at the junction between the sub-antarctic South 

 Pacific upper water and the eastern South Pacific central water. It was taken also at Station 943 off 

 the east coast of New Zealand, at a temperature between 7-37° and 7-40° C. It was taken in the Pacific 

 equatorial water by 'William Scoresby' in the Peru current (Sts. WS 687, 766) in 07 20' S. and 

 07 42' S. lat.
