The general map of the distribution of collections (Map I ) shows, by the location 

 of the red spots, all the localities from which collections of fishes have been made by 

 us in the work of the Natural History Survey. The distribution maps for the 

 various species indicate in the sam^ way all the localities from which representatives 

 of the species have been taken. For an accurate idea of the significance of these species 

 maps, each should be compared with Mop I.
