Remarks . — Boulenger " 

 has preferred to use Rana 

 halecina for the American 

 leopard frogs, citing Lin- 

 naeus^* as the authority 

 for this name, but is careful to state that the name appears in the 

 synonymy of Rana ocellata. In explaining the derivation of the name 

 halecina, Boulenger remarks that the " Sillhoppetosser " of Kalm ^' 

 has been latinized by Linnaeus. Kalm states that the Swedes in 

 America call these frogs "sillhoppetosser," or herring hoppers, in 

 allusion to the fact that they make their appearance early in the 

 spring at the beginning of the herring season. Rana halecina is 

 clearly employed by Linnaeus as a vernacular descriptive term in

 and Sci., vol. 55, no. 9, p. 433, Aug., 1920; Burt, C. E., Proc. Biol. Soc. Washington, vol. 44, p. 13, Feb.
