According to Van Denburgh, R. subaspcra differs from R. 

 holsti only in its more warty skin, and this does not seem to me to 

 justify the specific distinction. 



The above description is drawn up from the tj'pe specimen, the 

 only one I have seen, and from the accounts given by Barbour and 

 Van Denburgh, the latter having had the privilege of examining 

 an abundant material. 



I believe this remarkable form to be directly derived from rela- 

 tives of R. temporaria. I have recently given my reasons for not 

 accepting Van Denburgh's genus Babina (cf. C.R. Ac. Sc. Paris, 

 clxv, 1917, p. 989).
