EEPTILES. 465 



from both on account of its oblong rather crooked ear 

 swelling-. 



Is found in many places both in Sweden and Nor- 

 way, but it is not clearly ascertained how far north it 

 goes. I never saw one in Lapland, although frogs were 

 plentiful. 



15. B. VARIABILIS, Merr. Gronflackig Padda. 



Body covered with warts ; ear-knob large, flat, ob- 

 long; tympanum very apparent; hinder toes half 

 webbed ; fifth much shorter than the bottom joint of 

 the first ; in the common toad it is of an equal length ; 

 colour above green, with white streaks ; below white, 

 with irregular spots on the breast; length about 

 3 in. 



Is met with in the south of Sweden ; in many places as 

 common as the last. 



Bibron has decided that this is nothing more than a 

 variety in colour of the natter jack (B. Calamita), and I think 

 so myself. 



16. B. CALAMITA, Laur. Stink Padda. The Natter Jack. 



Body olive green above, covered with warts ; a smooth 

 yellow streak along the middle of the back to the anal 

 opening; length to anus 2-f in., to the point of the 

 longest toe 5 in. 



Nilsson remarks that there is a great resemblance be- 

 tween this and the last , but in the natter jack the hand 

 inwardly is rough with warts thickly placed together ; points 

 of the toes hard and brown ; first like fourth, third a little 

 longer, second longest. In B. variabilis the warts on the 

 hand are neither so close together nor so high ; the tips 

 of the toes of the same colour as the toes ; third like the 

 fourth, and shortish, second longest. 



These certainly, if constant, would seem to constitute 

 specific differences, but I think they are too slight to be 

 relied upon. Is met with in many tracts in the south of 

 Sweden.
