This subspecies which is confined to the West Indies and adjacent shores 

 of North and South America, appears to differ very slightly from the typical 

 form of the species and the var. comalensis. The worker is somewhat 

 smaller and often of a paler color, with the thoracic projections more feebly 

 developed and more rounded and the vestiges of the epinotal spines even 

 more insignificant. Both the petiole and postpetiole are considerably 

 broader, each being fully twice as broad as long. According to Emery the 

 male of vjijiufus has the head rotmded behind, but my specimens from the 

 Bahamas and Porto Rico have the posterior border of the head straight and 

 the posterior angles projecting as acute teeth. In the female the epinotum 

 is very steep, with small, blunt spines. Forel seems never to have accepted 

 this subspecies, and I am myself very doubtful Avhether it deserves to rank 

 as such. It is certainly much less distinct and less easily recognizable than 

 the following:
