18 THE SPECIES OF 



Not possessing a fresh specimen of this species, I am 

 not able to add a more detailed description to that of 

 Forbes, repeated above. My figure is a fac-simile of his. 

 In Gould's collection is a specimen said to have been 

 found at San Diego. The species has been attributed to 

 Central America, but probably through some error. 



Reeve's figure b seems more closely allied to H. areolata 

 or H. levis, than to the form figured by Forbes.
