 Wilder has expressed the supposition that all the members of 

 the subfamilies Plethodontinae and Desmognathinae may be lungless^ 

 and this seems still more probable now when some more species have 

 recently proved to be without lungs. But this peculiar character is, 

 as a rule not extended to the members of the subfamilies Salaman- 

 drinae and Amhlystomatinae. Camerano has made investigations 

 upon this subject* and not to mention the lungless forms, directed 

 his attention to Salamandra 2 sp., Chioglossa 1 sp., Molge 10 sp., Tyloto- 

 triton 1 sp. and Amblysfoma 1 sp. In all these forms he has found well, 

 although differently developed lungs. As this question is of great 

 interest, I think the following statements may not seem uncalled for 

 derived as they are from investigations of two rare genera not yet 

 studied with regard to this subject as well as of two species of 

 Amhlystoma and three species of Molge in which the condition of the 

 lungs was not known before. 



Molge vittata (Gray) 

 from Kadjani, Caucasus. The length of the lungs is a little more than 

 60 percent of the distance from the snout to the middle of the cloaca. 



Molge py rr ho g astra (Boie) 

 from Japan. The length of the lungs is not quite 60 (59,5) percent of 

 hte length of head and body measured as is mentioned above.
