hauled between 250-100 m. and twenty-two from nets hauled between 1000 and 250 m. (Text-fig. 35). 

 Hardy and Gunther (1935) reported it altogether nineteen times from the December-January Survey, 

 1926-7, in sixteen nets hauled between 1000 and 250 m. and the remainder from nets closing at 100 m. 

 The combined results of these three surveys show that the species was collected once in Antarctic 

 Surface Water, in the 100-50 m. nets, nine times in the nets hauled between 250 and 100 m. which 

 fished in Antarctic Surface Water and Warm Deep Water, and thirty-one times by the nets which 

 were hauled in the Warm Deep Water between 1000 and 250 m. These suggest that around South 

 Georgia, T. miilleri is essentially a Warm Deep Water species.

The occurrence of T. miilleri in the region of the Greenwich Meridian is shown both in Text- 

 figs. 4a and b (p. 167) and in Tables 17 and 18. It occurred at all stations made in this area, except 

 St. 2027. 



T. miilleri was never caught in very large numbers about the Greenwich Meridian, but nevertheless 

 it was collected with marked regularity at certain depths, particularly between 1000 and 250 m. In 

 January 1939, it occurred in all nets fished between 750 and 250 m. and in general at stations in the 

 Antarctic Zone it was taken fairly regularly in the Warm Deep Water. In contrast to the South 

 Georgia area where it was largely confined to the Warm Deep Water, on the Greenwich Meridian 

 it occasionally occurred in the summer months in some number in the surface layer. Nine catches of 

 T. miilleri were made in Antarctic Surface Water, south of the northern limit of Weddell Drift, 

 indicating that possibly the species migrates upwards into Weddell Sea Water at this season. In 

 winter, on the contrary, the collections along the Greenwich Meridian indicate that T. miilleri leaves 

 the top 250 m. of water and is more concentrated between 500 and 1500 m. than in the summer. 

 Between November and April, for example, thirteen successful hauls out of twenty-three were made 

 between 250-100 m. and seven successful hauls out of forty-one hauled between 1500-750 m. In 

 the May-September collections, however, the situation is reversed with one successful haul out of 

 nine between 250-100 m., but with eight out of seventeen collections in between 1500 and 750 m.
