B21U» Brussels. Wing 70.0, tail A.9. 5, exp. culmen 

 10.5, depth at base 3*^, tarsus 18.0, middle toe 

 minus claw 11. 5« Necessarily uhiesbrecht at 

 "Tabasco". 



Mounted bird in good condition; an adult male in good 

 pluinage v/ith a slight amount of abrasion evident on 

 tips of vdng (S: tail - hence probably spring or early 

 summer. 



Marked in the register by Dubois as "821^.. d - Mexique - 

 ? (type de taeniata BB). 



There are three birds in the collection (and register;, 

 the above No. 821/,; 821^b and 821A y. These latter 

 two were secured from Parzudaki, evidently at a date 

 later than the first because DuBus' description con- 

 tains no reference to the $ - v/hich surely would have 

 been described had he seen it. His description fits 

 v;ell with the above 821^ - including the "total 

 length". The Parzudaki birds are much longer. St 

 any rate the two later birds are typical of southern 

 Mexico in large size and olivaceous coloration. The 

 type is darker, still more richly colored, is small 

 in all dimensions and is certainly "aurantiacus ".

 Actually (by other species; it is San Pedro Tobasco 

 pres de Oaxaca but doubtless from another specimen. 



Meise in 1938 has also identified this specimen as the 

 type - and so indicated by tagging it.
