The general map of the ilistribution of coUectioiifj (Map I. ) shows, by the location 

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

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

 various species imlicate in the same way all the localities from which representatives 

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

 maps, each should be compared with Map I.
