they expected rain they cried much worse than commonly, 

 and began in the middle of the day, or when it grew cloudy, 

 and the rain came usually six hours after. As it snowed 

 on the 16th of the next month [April], and blew very 

 violently all day, there was not the least sign of them 

 at night ; and during the whole time that it was cold, and 

 whilst the snow lay on the fields, the frost had so silenced 

 them, that we could not hear one : but as soon as the mild 

 weather returned, they began their noise again. They 

 were very timorous, and it was difficult to catch them ; 

 for as soon as a person approached the place where they 

 lived, they are quite silent, and none of them appeared. 

 It seems that they hide themselves entirely under water, 

 except the tip of the snout, when they cry. For when I 

 stepped to the pond where they were in, I could not ob- 

 serve a single one hopping into the water. I could not 

 see any of them before I had emptied a whole pool, where 

 they lodged in. Their colour is a dirty green, variegated 

 with spots of brown. When they are touched they make 

 a noise and moan ; they then sometimes assume a form, 

 as if they had blown up the hind part of the back, so that 

 it makes a high elevation ; and then they do not stir, 

 though touched. When they are put alive into spirits of 

 wine, they die within a minute," {loc. New Jersey) 2nd

Apparently the frog Kalm heard was not the one he 

 caught. The cry is that of Hi/la pickeringii ; the frog 

 taken was probably that named by authors ^"Rana haledna 

 Kalm," the leopard frog. The name Rana haledna does 

 not occur in either of the editions of Kalm's work we have 

 at hand. That author's nearest approach to a Latin name 

 for the frog is in the description Rana virescens^ etc.^ and 

 it may rightly be objected to this that it was not given as 

 a binomial designation. That it was not regarded as such
