1. Plankton. 
Plankton from : Faroe Channel and Shetlands, including many new 
Radiolarians, Wolfenden (413); North Sea and Skagerack in 1900, 
seasonal distribution of Ciliata, Radiolaria and Dinoflagellata, Cleve (66); 
Cattegat and Baltic Sea, Dinoflagellata and Tintinnidae , Apstein (4); 
inland Norwegian Lakes, Dinoflagellata, Huitfeldt-Kaas (161) ; environs 
of Bologoe (Novgorod), Difflugia planctonica , n. sp., and Acanthocystis 
setifera , n. sp., Minkevich (265) ; the Volga, near Saratow, several Phyto- 
mastigina, Zykoff (440 & 441), and, various Protozoa, id. (439). 
Pinaciophora fluviatilis is reckoned as autopotamic , and only occurs 
besides in the Rhine. Tychopotamic are various spp. of Difflugia, Vorti- 
cella, most Suctoria etc. As a whole the Volga potamo-plankton is rich 
in Heliozoa, Zykoff (439). 
Protozoan plankton of the Moskwa river arranged according to oc¬ 
currence in flowing or stagnant water, Rossinski (320). 
Plankton from: Caspian Sea, various, Ostenfeld (277); bay of Sevas¬ 
topol, inch Pirophacus horologium St. rare, Minkevich (266); rivers 
Schoschma & Wjatka near Kasan, Zernow (437); Adriatic sea and Dal¬ 
matian waters PeHdinidce , Radiolaria and Foraminifera, Car (55) ; Gulf 
of Trieste, periodicity of, Steuer (380). 
The Coccolithophoridce as plankton-organisms in the Mediterranean. 
Bathymetrical distribution off Syracuse and other places, Lohmaxn (231). 
[For ingenious method used to obtain them see ii, F, 2.] 
Plankton from : lake of Monate, Garbini (135); Lake Achen in the 
Tyrol, distribution and periodicity of, Brehm (44); Schwarzsee near Kitz- 
biihel in the Tirol, with frequently the Ciliate Trachelophyllum apicudatum , 
Zacharias (431); lakes in Pomerania, and lake Dratzig, Voigt (406); 
great lake of Plon, various Ciliates, Voigt (404); Lake Erlauf, period of 
occurrence of Dinobryon spp. in, Brehm & Zederbauer (45); tributary 
of Moldau, in potamoplankton, Oxytricha pellionella and Stylonichia 
pustidata , Prowazek (300) ; Lakes of Schoh and Schluen, Zacharias 
( 433) ; Lake Aber or Wolfgang, time of occurrence of various Dino¬ 
flagellata and Vorticella , sp., in, v. Keissler (175); Lake of Alt-Ausser, 
various Dinoflagellata, v. Keissler (176); Lake of Neuchatel, including 
Stentor pohnnorphus , for the first time from the pelagic zone of a large lake, 
Fuhrmann (132). 
Horizontal and vertical distribution of Protozoan plankton from lake of 
Zurich, Lozeron (237). 
Atlantic Plankton with many new Tripylaria, Borgert (27). 
The Silicoflagellata are true plankton organisms: the peripheral spines 
of the skeleton seem to be longer in cold than in warm waters. Forms 
from Pacific plankton, Barbados and elsewhere, Lemmermann (222). 
Plankton from : Red Sea and Gulf of Aden, with new Ceratia and 
Cyttarocyclis , Ostenfeld & Schmidt (278); Indian Ocean, Thompson 
( 388) ; Indian Ocean and Malay Archipelago, new Radiolaria, Cleve (65). 
Phenomenal occurrence of Gonyaulax on the Californian coast, turning 
the water red by day and phosphorescent by night, Torrey (389). 
Colouration of standing water (in shallow easily-warmed ponds), owing 
to the rapid multiplication of various Flagellates, Zacharias (428 & 430).
