The only localities recorded for this species are Pacific 

 Ocean — Hong-Kong — and Red Sea (Griesbrecht), and from 

 the Arabian Sea by Professor Cleve. 



Pontella fera, Dana. 

 Occurrence ~No. 6. A night gathering, near the end of the 



Red Sea. 

 This species has been recorded from the Pacific and 

 Indian Oceans only ; the Red Sea is therefore a new 

 locality for it. 



Pontellina plumata (Dana). 

 Occurrence, Nos. 2, 9, 12, 16, 18. 



Pontellina plumata has a wide distribution, and has been 

 recorded from the Mediterranean, Atlantic, Pacific, and 

 Indian Oceans, but not from the Red Sea. 



Acartia negligens, Dana. 

 Occurrence, Nos. 1, 2, 3, 4, 5, 6, 8, 9, 13, 14, 10, 18, 20. 



This is a widely distributed species, and has been 

 recorded from the Mediterranean, Red Sea, and Pacific 

 Ocean. The Robinson collection extends its distribution 

 into the Indian Ocean. Cleve has recently recorded it 

 from the Arabian Sea and Malay Archipelago. 



Acartia erytlurea, Giesbrecht. 

 Occurrence, Nos. 1, 5, 0, 8. No. 1, Gulf of Suez ; 5, 6, 8, 



Red Sea. 

 Until recently the Red Sea was the only region where it 

 was known to live. Mr. Thompson (Trans. L'pool Biol. 

 Soc, Vol. XIV., p. 284), records it from the Indian Ocean, 

 and Prof. Cleve, op. cit., records it from the Malay 

 Archipelago. 



Oithona plumifera, Baird. 

 Occurrence, Nos. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 13, 14, 1G,
