ZOOGEOGRAPHY 2 S5 



Previous records. V.formosa was reported by Greeff (1885 as Alciopa longirhyncha) from off islands 

 in the Gulf of Guinea. Apstein (1900) reported Vanadis formosa and V. crystallina from numerous 

 localities in the South Atlantic between Ascension Island and the Equator and Ascension Island and 

 the mouth of the Amazon. Monro (1930, 1936) recorded V.formosa from several stations made by 

 ' Discovery ' Investigations in the Tropical and Sub-Tropical Zones, and he also reported V. crystallina 

 in 1936 from the Cape Verde to Falkland Islands line of stations. From the 'Meteor' collections, 

 Friedrich (1950c), reported V. crystallina but he gave no details. 



Rhvnchonerella angelini 



(Text-fig. 50) 



R. angelini is known from few records, all from the Sub-Tropical Zone, and it is possible that it is 



limited in its southerly distribution at the Sub-Tropical Convergence. This species may measure up 



to 67 mm. in length and would normally only be caught by the larger nets. 



The following records of R. angelini, except that from St. 74, are taken from Monro's 1930 1 and 

 1936 Discovery Reports; all these specimens have been re-examined: St. 74, N 70 V, 1000-0 (1); 

 St. 250, TYF, 300-0 (2); St. 257, TYF, 250-0 (1); St. 268, TYF, 1 50-100-0 (1); St. 405, TYFB, 

 1200-0 (1). R. angelini was caught in South Atlantic Central Water at Sts. 250, 257 and 260; at 

 Sts. 74 and 405 it could have been collected in either South Atlantic Central Water or Antarctic 



Intermediate Water. 



Previous records. Records of R. angelini from the South Atlantic were made by Greeff (1876, as 

 Callizona grubei) and Levinsen (1885, as Callizona grubei) all north of the Sub-Tropical Convergence. 

 Friedrich (1950c) reported it from the 'Meteor' collections (as Callizona angelini) but gave no details. 



Krohnia lepidota 



(Text-fig. 50, Table 30) 



K. lepidota is known from few records all north of the Sub-Tropical Convergence and it is possible 



that this boundary restricts its southerly distribution. Measuring up to 50 mm. long K. lepidota was 



normally only collected by the larger nets but a fragment was caught by the N 50 V at St. 2641. 



In the Sub-Tropical Zone K. lepidota was caught in South Atlantic Central Water at St. 254 and 

 in this water mass, or Antarctic Intermediate or Warm Deep Water at St. 2632. In the Tropical Zone 

 K. lepidota was collected at all stations in either Tropical Surface Water or South Atlantic Central 



Water.

Previous records. K. lepidota was reported by Apstein (1900, as Callizonella lepidota), from four 

 stations between the Equator and Ascension Island, and at three between Ascension Island and the 

 mouth of the Amazon. Under this name also, Friedrich (1950c) reported K. lepidota from the 

 ' Meteor ' collections in the South Atlantic but he gave no details. 



1 Monro's specimen from ' Discovery ', St. 245, was not deposited in the British Museum (N.H.) collections.
