BIGELOW: EXPLORATIONS OF THE COAST WATERS. 



289 



The occurrence of hyperiid amphipods other than Euthemisto, 

 in 1914, is given in the following table. 



In 1915 Parathemisto oblivia was taken again off Shelburne (Station 

 10291, five specimens); Hyperoche and Hyperia at several stations 

 in the Gulf: Phronima on Brown's Bank (Station 10296) and off 

 Marthas Vineyard (Station 10333). 



The rarity of Parathemisto reproduces our experience in previous 

 years (1914a, 1914b, 1915), and its repeated occurrence close to the 

 southern coast of Nova Scotia suggests that when it does reach the 

 Gulf, it is brought thither by the St. Lawrence water.^ Hyperoche 

 was much more common in 1912 and 1913 than in 1914 or 1915 and 

 more generally distributed; and neither of the two species of Hyperia, 

 //. (jalha and //. medusannn, was found in 1914, though both were 

 common in previous summers. Especially interesting is the large 

 haul of oceanic warm water speciies at Station 10218. Two of these, 

 Phronimella and Phrosina, are now recorded for the first time from 

 our waters so far as I can learn (Holmes, 1895). But as both are 

 widely distributed in the Atlantic (Bo\Tillius, 1889) there is nothing 

 remarkable in their occurrence in the inner edge of the Gulf Stream. 



Copepods. — Our records for this group in the Gulf of Maine add 

 little except in the way of verification, to those for 1912 (1914a) and 

 1913 (1915). 



In 1914 and 1915 as in previous summers, Calanns finmarchicus 



> Parathemisto is recorded from the Gulf of St. Lawrence by Whiteaves, ibOl.
