Thierische Organismen der Brunnemvasser von Prag, p. G4, pi. vii. fig. 6, 
fully described; also mentioned by the same in “0 puvodu Fauny

COPEPODA. 
W. Giesbrecht has published a valuable work (title, see supra), de- 
scribing and figuring 23 species of free Copepods observed in the inlet of 
Kiel ; he points out many secondary sexual differences, and supposes that 
the anterior appendages of the antennae, which are found in both sexes 
and all ages, may be destined to distinguish the quantity of salt in the 
water. He proposes to divide the free Copepods in two groups ; Gymno- 
pleoda , pleon without feet, and Podopleoda , a pair of feet on the first 
segment of the pleon.

CyCLOPIDjE. 
Cyclops. A. Fric, Zool. Anz. 1882. pp. 502 & 503, subdivides this genus 
into two groups : — 
1. The Dolichopoda. Body in the Nauplius- and Metanauplius-stages 
oval, all feet natatory, long, the third pair provided with a long natatory 
branch ; antennal gland straight. C. viridis , siynatus, tenuicornis , and 
Brachypoda. Metanaupli us-stag e compressed, third pair of 
appendages crooked, serving only for seizing the food. C. serrulatus } 
fimbriatus , and canthocamptoides . 
Cyclops pulcliellus (Koch), nanus (Sars), and fimbriatus (Fischer), found 
in wells at Prague ; Yejdovsky, Thier. Organ, p. G3, pi. vii. figs. 7-13.
