species herein included, and should, therefore, be held responsible 

 for the nomenclature as it now appears. For convenience the 

 arrangement of Sclater and Salvin's 'Nomenclator' is followed, 

 and with certain exceptions the nomenclature there employed is 

 adopted.— F. M. C] 



1. Merula fumigata {Licht.~). — Common in semi-palm growths; fre- 

 quently observed flying low along the forest paths; making short flights 

 and re-alighting before you. 



[Three specimens are apparently typical of this species and agree 

 closely with Maximilian's types of Turdus ferrugineus. Two individuals 

 show a marked variation in size. A male taken June 25, 1887, measuring, 

 wing, 4.29; tail, 3.48; tarsus, 1. 21; exposed culmen. .78 ; while a female, 

 taken July 1, 18S7, measures, wing, 4.72; tail. 3. So; tarsus, 1.20; exposed 

 culmen, .82 inch. — F. M. C] 



2. Mimus saturninus (Lickt.). — A female, captured August n, 1887, in 

 a semi-palm thicket was the only one observed. 



[This specimen measures (skin), length, 9.00; wing, 3.96; tail, 4.18; 

 tarsus, 1.22; gonys, .41 inch ; (mandible broken). It is evidently similar 

 tothe bird from Para on which Lichtenstein based his description of Tur- 

 dus saturninus. Specimens from Bahia, to which the name saturninus has 

 generally, but I believe wrongly, been given, differ greatly from the San- 

 tarem bird both in size and coloration. An example from Dr. Lacerda 

 measures (skin), length, 11.00; wing, 4.38; tail, 5.10; tarsus, 1.40; ex- 

 posed culmen, .S2 ; gonys, .51 inch. It is much browner above and more 

 buffy below than the Santarem bird. Lichtenstein gives the length of 

 his Para bird as 9 inches, and says, "Cauda breviorquam in T. polyglotto." 

 His description of U T. folyglottos Lin.," number 445 on the same page of 

 the 'Verzeichniss' as the original description of saturninus, with the 

 habitat given as "Am. sept.," enables us to recognize the bird with which 

 he made his comparison as undoubtedly the Mimus folyglottos of recent 

 authors. In this species the tail averages about 5 inches ; longer, there- 

 fore, than in the Santarem bird, which thus agrees with Lichtenstein's 

 type, but shorter than in the bird from Bahia. Aside from geographical 

 reasons it is evident, therefore, that the name saturninus belongs to the 

 Lower Amazonian bird and is not applicable to the bird from Bahia, 

 which, being thus left without a name and being evidently worthy of 

 recognition as a distinct species, may be called 



Mimus arenaceus, sp. nov. 



Sp. Chars. — Similar to Mimus saturninus (Licht.) but larger and much 

 browner above, the feathers of the rump sandy brownish without darker 

 centres, the underparts with a suffusion of buffy which is heavier pos- 

 teriorly.
