Trib. 3. ( 'yclopoidea. 



Fam. 1. Oithonellidæ. 



323. Oithonella 1 helgolandica. Claus. 



< = OithoTia pygmtsa, Boeck). 



Fortiden nærmere Kysten blev denne Art observeret 

 i det aabne Hav paa Stat. 96 Vest af Nordlandskysten, 

 som sædvanlig svømmende lige i Vandskorpen. Arten, 

 der er meget almindelig ved vor Syd- og Vestkyst, er forst 

 beskreven af Claus fra Heleoland. 



Fam. t. Cyclopidæ. 



324. Cyclops strenuus, Fischer. 



Observeret under Expeditionen i Vandpytter nær Reik- 

 javik (Island). Arten, der alene synes at være indskrænket 

 til mindre Vandansamlinger, synes at have en vid Udbred- 

 ning over Europas Fastland og de britiske Wer. 



325. Cyclops gigas, Claus. 



Ikke sjelden sammesteds melleni Mudret paa Bunden 

 af Dammene. Arten, der er meget almindelig hos os og 

 udbredt til de britiske Øer og Mellemeuropa, forekommer 

 foruden i mindre Damme ogsaa i storre Indsoer, hvor den 

 gaar ned til meget betydelige Dybder (50 Favne).

Ved at conferere med det nylig af Brady udgivne 

 Copepodeværk har jeg overbevist mig om, at denne af mig

 jeg foretaget ovenstaaeude Forandring.

Fam. 1. Oithonellidæ. 

 323. Oithonella 1 helgolandica, Claus. 



(= Oitluma pyymæaj Boeck). 



Besides in comparative proximity to the coast, this 

 species was also observed in the open sea, at Station 96, 

 west of the coast of Nordland, swimming about as usual 

 at the surface of the water. The form — very common 

 off the south and west coasts of the country — was first 

 described by Claus, from Helgoland. 



Fam. 2. Cyclopidæ. 



324. Cyclops strenuus, Fischer. 



On the Expedition, observed in pools of water near 

 Reikjavik (Iceland). The species, that would appear to 

 occur exclusively in small pools and lakelets, has, it seems, a 

 wide distribution over the eontinent of Europe, including 

 the British Islands. 



325. Cyclops gigas. Claus. 



Not infrequently met with betwixt the mud at the bot- 

 tom of the same pools. The species — very common in Norway 

 and extending to the British Islands and Mid-Europe — 

 occurs not only in pools and ponds, but also in lakes of 

 greater extent, where it descends to a very considerable 

 depth i 50 fathoms).

On referring to the work on the British Copepoda' lately 

 published by Brady, I have come to the result that the

 in Zoology, I have selected the above modification.
