Die Greiftaster der çj^ haben die Form, wie sie Fig. 1 zeigt, 

 wobei zu bemerken ist, daß / den linken und r den rechten Taster 

 darstellt, beide Taster aber etwas gequetscht wurden.

Die Furcalglieder sind nur wenig gebogen; die beiden an der 

 inneren Curvatur deutlich bedornten Endklauen sind fast drei Viertel 

 so lang wie der Hinterrand des Furcalgliedes, genaues Verhältnis 

 = 14 : 20. 



5. Salamanders with and without lungs. 



By Dr. Einar Lönnberg, Upsala, Schweden. 



eingeg. 10. November 1899. 



By the investigations of Harris Wilder, L. Camerano, 

 P. Moore and the present author it has been proved that many sala- 

 manders are normally deprived of lungs. To the list of such species I 

 am able to add two namely: Spelerpes longicauda [Gveen) and Spelerpes 

 gtittolmeaius (Holbrooki. At least the former of these seems to have 

 terrestrial habits as Cope in his work on »the Batrachia of North 

 America«^ says (p. 169): »This .... is almost always found in rocky 

 ground and in fissures and caves in cliffs. I have never seen it in the 

 water.« The habits of the latter species are not known to me and 

 Cope does not say anything about the same in the work mentioned. 

 The list of Salamanders known to be without lungs or to have 

 these organs reduced is as follows: 

 Subfam. Salamandrinae: 



Salamandrina perspicillata (Savi) (rudimentary: Camerano). 

 Subfam. Amhlystomatidae: 



Amhlysioma opacum Gravh. (highly reduced, rudimentary: 

 Lönnberg). 

 Subfam. Pleihodontinae : 



Anaides lugubris Hallow (absent: Wilder), 



Plethodon cinereus (Green) (absent: Wilder), 



P. c. erythronotus (Green) (absent: Wilder), 



Plethodon gluiino sus (Green) (absent: Lönnberg, Wilder),
