DISCOVERY REPORTS 



In the Tropical Zone this species was caught in either Tropical Surface Water or South Atlantic 



Central Water at all stations except 690, in which the net may have also collected it in Antarctic 



Intermediate Water. . , 



Table 26. Occurrence of Tomoptens elegans 



Previous records. Ehlers (19 17) recorded T. elegans from several localities in the Tropical and Sub- 

 Tropical Zones of the South Atlantic all from nets fished through the surface waters. Friedrich 

 (1950 c) may have included this species in the Tomopteridae of the ' Meteor ' collections which he 

 reported from the South Atlantic. 



Tomopteris apsteini 



(Text-fig. 48, Table 27) 

 T. apsteini was collected only in the Sub-Tropical and Tropical Zones and it is evident that it is 

 restricted in its southerly distribution by the Sub-Tropical Convergence. This species measures from 

 8 to 47 mm. in length and could have been caught by all the nets used in Discovery Investigations. 

 In the Sub-Tropical Zone T. apsteini was collected in South Atlantic Central Water at Sts. 247, 

 254, 259, 672, 674, 676, 677 (420-0 m.) and 2032. At St. 1555 it may have been caught also in 

 Antarctic Intermediate Water and at St. 677 (2000-0 m.) also in the Warm Deep Water. In the 

 Tropical Zone, where T. apsteini was collected only at stations made along the 30 Line, it was caught 

 by nets which fished in both Tropical Surface Water and South Atlantic Central Water. 



Table 27. Occurrence of Tomopteris apsteini 



Previous records. T. apsteini was collected in the South Atlantic by the Deutsche Siidpolar- 

 Expedition (Ehlers, 191 7, as T. rosaea) and possibly also by the ' Meteor ' expedition (Friedrich, 1950c, 

 as Tomopteridae). 



Vanadis formosa and Vanadis crystallina 



(Text-fig. 49, Tables 28 and 29) 

 V. formosa and V. crystallina are closely related and are therefore considered together. Both species 

 inhabit the Sub-Tropical and Tropical Zones and are restricted in their southerly distribution by the 

 Sub-Tropical Convergence. Each is a large species, V. formosa measuring up to 300 mm. in length
