the apex of the bract, and sometimes flattened on its ventral side. The female gonophore bears from 

 fourteen to sixteen eggs. 



There is not enough material for a study of the details of the tentilla. 



Material. Two eudoxids, six bracts, fifty-four gonophores. 



The complete eudoxid from 'Discovery II' Station 1588 is chosen as holotype. It bears the 

 Brit. Mus. (Nat. Hist.) Register No. 1952. 11. 19. 3. 



Muggiaea atlantica Cunningham, 1892. 



Russell (1934) published interesting information on the occurrence of the two hitherto known species 

 of Muggiaea. He thought that both are essentially inhabitants of less contaminated coastal waters, 

 a fact which he suggested would account for their absence from the collections of Oceanographical 

 Expeditions. 



This species occurred abundantly near the surface off South Africa at 'William Scoresby' 

 Stations 444-460. 



Bigelow & Sears (1937) most recently summarized our knowledge of the distribution of M. atlantica. 

 The 'Trior' records made these authors think that it is definitely a neritic species, as are probably 

 also M. kochii, Diphyes chamissonis, Lensia subtilis and L. subtiloides. 



Fraser-Brunner took Muggiaea atlantica in the Gulf of Aden (Chart, p. 10) off Aden and Alayu, 

 localities which bear out the idea that it is definitely a neritic species. 



'Manihine' took a single nectophore at each of three stations, 10 miles, 35 miles and 40 miles east 

 of Sanganab Lighthouse, off Port Sudan. All the hauls were made from depths of 365 m. to the 

 surface in January 195 1.
