It is probable that S. Seripensis is the II. cciferata, var. Gigaxii, 

 of Jeffreys and other British authors, and from the description given 

 in tlie Fauna Earopcca Ilolluacorum Extramarinorum Prodronms (1876) 

 it is the H. Gigaxi of Westerlund. 



In this work (p. Ill) Westerlund records H. Gigaxi as occui'ring 

 in " Lusitaniii, Gallia, Britann., Belgia ". 



Locard ' includes twenty-three 'species' under the group of 

 H. Heripensis, one of which is H. Gigaxi. This latter form is stated 

 to be met with in southern France, while H. Heripensis is recorded 

 from northern and central France.
