In Mr. G. W. Herdman’s collection the Copepoda are 
distributed as follows :— 
Calanide ae A 8 species. 
Centropagide ... ae ee 
Candaciidee (as se a, tae 
Cyclopidee oe ie ype | 
Harpacticide ... nhs Se. 
Corycoeidee sa) a TASaes: 
The various species in each collection will be found 
tabulated later, with the number of the bottles or stations 
in which they occur. 
The other organisms found consist chiefly of Diatoms, 
Peridinie, Foraminifera, Globigerine, Radiolaria, Ptero- 
pods, Sagitte, Ostracoda, Cladocera, Schizopoda, Amphi- 
poda, Myside, Salpe—most of which were generally dis- 
tributed throughout the area traversed. Ceratwum tripos 
was the most common of the Peridinie ; it was generally 
present throughout, always as the variety macroceros, 
Ehr., the three horns of which, and especially the lateral 
ones, are very long and slender. 
Some complete Pteropod shells containing their mol- 
luscs fully expanded were found in No. 17 (Wyse), taken 
in the Red Sea. Also, in one of the Red Sea gatherings, 
was the well-known micro-alga, Trichodesmium erythreum, 
which is said to give to the Red Sea itsname. These 
minute cylindrical conferve, are found in bundles of from 
20 to 60 in each. - Darwin, in the ‘‘ Voyage of the 
‘Beagle,’’’ aptly describes them as like chopped bits of 
hay. He saw them in bands about 10 yards wide, and at 
least 24 miles long. They have been frequently observed 
in both the Atlantic and Pacific Oceans, in large patches 
of a brownish yellow, and sometimes blood-red colour. 
It will be observed from Capt. Wyse’s and Mr. G. W.
