 with black hairs. It has a black edging or border, which is broad-

The following races are recognized: 



quadrtvittatus Say, the typical form, much paler and 

 grayer than the above described. 



neglectus Allen, a bright-coloured form, tinged yellow 

 on hinder parts. 



horealis Allen, smaller and yellower than quadrivitta- 

 tus, but not so bright as neglectus; gray on rump. 



gracilis Allen, a larger, slenderer, and more intensely 

 coloured race than quadrivittatus, with the black 

 marks replaced by reddish brown. 



luteiventris Allen, above brighter coloured than quad- 

 rivittatus and below buffy. 



felix Rhoads, a darker race than the typical. 



affinis Allen, a larger race; gray, especially on rump.
