I find this species extremely variable in the divergence of the ros- 

 trum and in the antero-external angle of the basal joint, which is some- 

 times unarmed and sometimes armed with a small spine. The species 

 ranges from Vineyard Simnd to the west coast of Florida, and the more 

 northern specimens, that is, from Vineyard Sound to Beaufort, are those 

 most likely to present the antennal spine, while the southern forms have 

 usually a blunt angle at that point. There is no constancy in this oc- 

 currence, however, and no accompanying characteristic that is invari- 

 able.
