Lungless Salamanders. 
Second paper. 
By Harris H. Wiper, 
With 7 figures. 
In the Anatomischer Anzeiger of Jan. 20, 1894 (Bd. IX, no. 7) 
I published an article entitled ‘Lungenlose Salamandriden’ in 
which I enumerated four species of American Salamandrids which in 
the adult state were totally without lungs, trachea or larynx, although 
the gills had disappeared at the end of larval life as in normal forms. 
Soon after this CAMERANO found the same lungless condition in two 
Italian species!), thus increasing the number to six. In this paper 
I will add largely to this list, which will establish the fact that in the 
Salamandridae lungless species areas numerous as those 
possessing lungs, and that in consequence of this the 
definition of the group must be modified. Before enumer- 
ating the new forms it seems necessary to correct some errors in the 
determination of the first four species. 
The species quoted by me as Gyrinophilus porphyriticus is Spe- 
lerpes porphyriticus of authors, as the genus Gyrinophilus, Cope 
1868 has not been generally accepted as distinct from Spelerpes, Ra- 
finesque ?).
