In a considerable measure the above list is a repetition of the first. Only four 

 species comprised in the first list are wanting in the second, while only nine additional 

 ones are to be found in the latter. This close agreement is doubtless due to the fact that 

 the Fish Hawk stations in Vineyard Sound are more than three times as numerous as 

 are those in Buzzards Bay. They thus have an undue share in determining the character 

 of the first of our lists.
