THRYOTHORUS LUDOVICIANUS BERLANDIERI (Baird). 

 BERLANDIER'S WREN. 



Similar to T. I. ludovicinmis but slig'htly smaller, bill larger, upper 

 parts duller brown, and under parts much deeper colored (usually deep 

 clay color or approaching tawnj^-ochraceous, still deeper on flanks), 

 the sides and flanks frequently barred with brown or dusky. 



former, and consequently I refer them to the Florida form. The only alternative 

 would be to separate them subspecifically, since they differ materially from T. I. 

 miamensis only in size, while they differ from T. I. ludovicianus both in size (wing, 

 tail, and middle toe shorter, but bill longer) and coloration. Average measure- 

 ments of specimens from the tj'pe locality of T. I. miamensis, of birds from other 

 parts of southern and central Florida, of a series from the Suwanee River, and of 

 T. I. ludovicianus, compare as follows:
