present between the warmer AW and the

colder NW. AI, of which several types can

be distinguished, is formed north of the

Arctic (or Polar) front in the Iceland and

Greenland Seas. From the areas of genera-

tion AI sinks and spreads to the northern

slope of the Faroe-Iceland Ridge which it

follows towards the Faroe plateau and into

the Faroe-Shetland Channel. In the Faroe

area this water usually has a temperature

between 1.5and3.5 °C.

Water with temperatures between 3.5

and 7.0 °C is a mixture of AW and AI.

Colder water with temperatures between 0

and 1.5 °C found north of both the Faroe-

Iceland Ridge and of the Faroe plateau, and

in the Faroe-Shetland Channel is a mixture

of AI and NW. Water of the same tempera-

ture range south of the Faroe-Iceland Ridge

is a mixture of AW, AI and NW.

For each species in the systematic list be-

low the following information is given: the

valid name with author and publication

year; synonyms when relevant; reference to

a good description of the species; previous

Faroese records; the BIOFAR and BIOFAR

2 stations where it was found; area descrip-

tions (Fig. 1); depth range; measured tem-

perature range or estimated temperature

range of the near-bottom water (based on

data from a database created by H. Wester-

berg, in Nørrevang et ai, 1994); the type of

water mass in which the species was caught

(identified by H. Westerberg, in Nørrevang

et al., 1994); and short notes on the distri-

bution and the depth range of the species in

the Atlantic Ocean. Data on the distribution

and the depth range of the species in the At-

lantic Ocean are taken from the monograph

on the British Mysidacea by Tattersall and

Tattersall (1951) and the World List of the

Mysidacea by Mauchline and Murano

(1977). Newer results adding to the geo-

graphical distribution and depth range are

referred to. The habitus drawings presented

are from Tattersall and Tattersall (1951).
