Dr. Suckley gave some measurements, derived from examination of three 

 fresh specimens, as follows: —

A few years later, in 1864, Professor Peters (I. .v. c.) described specimens 

 from California as constituting a new variety, to which he applied the name 

 of Haplodon leporinus var. californicus. I have, seen no specimens from that 

 region, nor is the material available at present sufficient to enable us to come 

 to final conclusions respecting the normal rate of susceptibility to individual 

 variation. The few specimens, however, indicate that the rate is at least as 

 high as that which has been established for various mammals more or less 

 closely allied ; and, should such prove really the case, there would be no impro- 

 priety in considering var. californicus as strictly synonymous.
