18. Laphodytes cucullatus Hooded Merganser, 

 "fish duck," "hairyhead," "sawbill." In Barnard's 

 time this species was found frequently, but it is now 

 a rather rare transient, or possibly winter visitant. 

 Dr. Warren has the following records: Nov. 23, 

 1881; Apr. 3, 1884; Mar. 26, 1887; June 23, 

 1890 (Bds. Pa., 1890, 35). Three specimens were
