93. Myrmotherula, sp. ? 



Santa Fe. 



Arce has sent a single specimen of a female of a species of Myr- 

 motherula, whicli I have never heen able satisfivctorily to determine. 

 It agrees with specimens I obtained in Vera Paz.

Santiago de Veragua. 



This species is very closely allied to R. cinereiventris, Sclatei', if 

 really distinct. The most obvious and, indeed, the only point of dif- 

 ference seems to consist in the much less extent of the postocular spot.

Santa Fe. 



A single specimen from this locality agrees accurately with our 

 type from Tucurriqui, Costa Rica.

In the plate above referred to, the artist has represented this bird 

 on a stone surrounded with water. This is manifestly erroneous, as 

 all members of this genus, and, indeed, of the whole family, frequent 

 the thin undergrowth of the virgin forest. Formicarius Hies little, 

 but follows the ant-paths, walking and running on the ground 

 amongst the decayed leaves, occasionally mounting a prostrate tree. 

 F. moniliger, Scl., has a sharp clear cry.

A single immature bird from this locality would, no doulit, in the 

 adult state agree with our Costa Rica speolmen mentioned in the 

 above reference. This, as I there observed, differs somewhat from 

 southern specimens ; but my materials are still insufficient to deter- 

 mine whether the dilferences are constant or not. F. hoffmanni, Cab., 

 doubtless also occurs in this portion of Veragua, as it is found both 

 at Panama and in Costa Rica. We thus have three very distinct
