SIPHONOPHORE FAUNA OF RED SEA i 3 



identification of young nectophores and a few larval bracts, and needs corroboration. The rather 

 uncommon, associated pair Diphyes chamissonis and Lensia subtiloides are abundant. 



Comparison of the records from the northern, central and southern areas of the Red Sea, for what 

 they are worth, show that there are eleven species in the southern, twenty-one in the central and 

 seventeen in the northern. All the records are winter ones. 



Red Sea records by the ' Manihine ' for the ten following species show that they were living at the 

 upper limit of their known temperature range : Diphyes dispar, D. bojani, D. chamissonis, Lensia 

 subtiloides, L. subtilis, Chelophyes appendiculata, Eudoxoides mitra, Abylopsis tetragona, A. eschscholtzii, 

 Bassia bassensis. 



SIPHONOPHORES FROM THE GULF OF ADEN 

 From the Gulf of Aden, where forty-five 'Mabahiss ' Stations were made, five hauls were made with 

 plankton nets but only nine Siphonophores were captured. However, Mr Fraser-Brunner, who made 

 some very rapid oblique hauls off Aden, Mukalla, Alayu and Bulhar on 10 and 26 November 1948, 

 on 5 and 6 December 1948, and on 23 February 1949, respectively, showed that the water was 

 teeming with Siphonophores. He took more than 9000 specimens, yet Vogtia glabra was caught by 

 the ' Mabahiss ' and missed by Fraser-Brunner, probably because it is not a surface species. 

 One station, No. 2681, was also made by R.R.S. 'Discovery II ' in 1950 in the Gulf of Aden.
