411. (^n Myrmeciza laemosticta Sal v. and M. stictoptera Lawr. 



The Tring Musenm possesses eight specimens of a !\fiirmrci~(i, collected by 

 Mr. C. F. Underwood, near Carrillo, Costa Rica. Three of them, as well as a 

 ■ipeeiraen from the same locality in the British Mnseum, agree perfectly with the 

 original description of Af. stictoptera Lawr. All are marked c? by the collec'tor. 

 Tiie live other skins at Tring, an example from Carrillo, and one from Santa F<', 

 Veragna (Arce), in the British ]\Insenm, all marked ? , dift'er in having the chin 

 and fhr(];Lt spotted with white (instead of uniform blackish), the foreneek slate-grey 

 like till' abdomen (not blackish like the tliroat), the white on the bond of the wing 

 nuich less extended, oi- even wanting, anil the pileura strongly washed with olive 

 lirown. This series agrees in every resjiect with the unsexed type of il/. laemosticta 

 Salv. from Tncurriipii, in the British Mnseum. In all other characters, snch as the 

 ])attern of the wing-coverts, the i)resenco of a large white interscapular blotch, the 

 length of wing and tail, the shajie of the bill, etc., the two series agree perfectly 

 with each other; and as some of the specimens with a spotted throat were
