the samples, were not selected from this point of view, and as the istrnments, by which the different 

 hauls are made, are widely different, the results arrived at are only to be compared with caution, and 

 are not expected to give more than an impression. For getting an exact knowledge of the vertical 

 and seasonal distribution of a species like C alarms fin mar chictis, we are obliged to have at our 

 disposal numerous samples taken with a closing net at the different hours of the day, and in the 

 succeeding months of the year at the same localities, scattered over a wide area. Most of the samples 

 at my disposal are surface ones; the vertical hauls are not procured with a closing net. L,ike most 

 expeditious in these regions the Ingolf Exp. etc. has only taken plankton samples in the months of 

 the summer (May to September) and seldom in different months in the same region. 



West coast of Greenland. The Ingolf Expedition has in the months of June and July 1895 

 taken several samples with C. finmarchicus.
