The Ichth}'ological collections of this Expedition are very rich and very valuable 

 in spite of the fact that a considerable part of the same was lost when the ship 

 "Antarctic" foundered the I2th of Febr. 1903 after it had been crushed by the ice. 

 This must be the more deplored as the lost material was collected in several locali- 

 ties of great interest, among which may be mentioned the cold basin of Bransfield 

 Strait, where the bottom temperature was found to be — 1,65° C, the Gerlache Canal 

 etc. Nevertheless, although the result with regard to the widening of the knowledge 

 about the Antarctic Ichthys is not so great as it, with a little better luck, could have 

 been, very important facts have been gathered concerning the geographical distribu- 

 tion of different species of fish, and quite a number of species and subspecies are 

 in the following pages described as new to science. This, on the whole and under 

 the prevailing circumstances gratifying, result is chiefly due to the assiduous efforts 

 and energy of the Zoologist of the Expedition, Mr. K. A. Andersson, who has 

 caught nearly all of the fishes himself. It is a great pleasure to me to publicly 

 acknowledge this here and tender him my best thanks for his valuable work and 

 for the information concerning the capture of the different specimens etc. which he 

 has given me. I wish also to give my compliments to Mr. C. Skottsberg, the 

 Botanist of the Expedition, who from living specimens has skilfully prepared the 

 coloured figures which accompany this paper. Thanks to this, the reader has the 

 pleasure of getting a fair idea of the beautiful colours of some of the antarctic 

 fishes. The figures on the second plate are of special interest, because the original 

 specimens to them belonged to the material which was lost in the shipwreck.
