ZOOGEOGRAPHY 245 



Travisiopsis coniceps 



(Text-fig. 45, Table 20) 



T. coniceps is widely distributed throughout the South Atlantic, and, measuring 18-30 mm. in length, 

 could have been collected by all nets used in Discovery Investigations. 



In the Antarctic Zone T. coniceps was collected in the Warm Deep Water only. In the Sub- 

 Tropical Zone it was caught in South Atlantic Central Water at St. 1772 and at Sts. 78, 85 and 100, 

 where the nets were hauled open to the surface; it may also have been collected in Antarctic Inter- 

 mediate Water or Warm Deep Water. It is probable that this species normally inhabits the deeper 

 water masses and this may explain the absence of records from the Sub-Antarctic Zone and the Sub- 

 Tropical Zone, north of St. 100, from which regions comparatively few samples have been examined 

 from depth. 



* Heavy type indicates a night haul. f (-0) indicates that the net failed to close and fished open to the surface. 



Previous records. Monro (1930, 1936) reported T. coniceps as Sagitella lobifera from the Antarctic 

 Zone at St. 395, and in the Sub-Tropical Zone from Sts. 78, 85 and 100; these records are listed 

 above. Stop-Bowitz (1951) reported it from 49 56' S., 49 56' W. 



Travisiopsis lobifera 

 (Text-fig. 45, Table 21) 



T. lobifera was collected only in the Sub-Tropical and Tropical Zones, and, although the records for 

 it are few, its absence from all stations south of the Sub-Tropical Convergence provides some evidence 

 that it is restricted in its southerly distribution at this boundary. This species measures up to 25 mm. 

 in length and could have been caught by most of the nets used in Discovery Investigations. 



In the Sub-Tropical Zone, T. lobifera was caught in South Atlantic Central Water at Sts. 259 and 

 1600 and in Antarctic Intermediate Water at St. 1606. In the Tropical Zone it was collected in 

 Tropical Surface Water or South Atlantic Central Water. 



Previous records. Levinsen (1885) reported T. lobifera from the Tropical Zone in n° 50' S., 

 8° 10' W., and i 5 °6'S., 6° W.
