190 MR. 0. SALVIN ON THE BIRDS OF VERAGUA. [Mar. 24, 
whether the grounds for their separation are based upon sufficiently 
constant characters. 
From Mr. Lawrence’s descriptions I gather that S. semicollaris 
has a white patch on each side of the neck, but no collar interrupting 
the uniform black of the chin, throat, and breast. S. collaris has a 
narrow white collar. S. Aicksi has the throat white and a collar 
uniling with it. S. fortipes has a white patch on each side of the 
neck connected with a narrow collar, and thus differs from S. seme- 
collaris, but resembles S. col/aris, with which it is not compared.. 
Have we here really more than one variable species ?

This species ranges as far south as Panama (Scl. & Salv. P. Z.S. 
1864, p. 353). The presence of C. columbiana, Lafr. (Lawr. Ann. 
Lye. N. Y. ix. p. 103) in Costa Rica is at present hypothetical. 
Ocyalus wagleri. 
Chitra ; Calobre.

This is the most northern locality yet recorded for this wide- 
ranging species. It is found at Panama but not in Costa Rica.
