Fel)ru:iry. IFo describes it as e.\cee(liii;>ly tiune aud gentle in its habits, and 

 with a sonj,' reniaikably nielodicnis and attractive. I'erclied un the topniuMt 

 Ijougli oi' a tloweriny mimosa, in the presence of his consort, the male will 

 ])our forth a volume of must enchanting music. Their nest is generally very 

 nearly Hat, measuring nearly si.x inches in circumference, and scarcely more 

 than an inch in its greatest thickness. Tt has hardly any distinct cavity, 

 and liollows but very slightly from the rim to tiie centre, its greatest depres- 

 si(jn having barely the depth of half an inch. The nests are composed of 

 long coarse fibrous roots, rudely, but somewhat con^jactly interwoven. The 

 iimer framework is constructetl of the same materials intermi.xed with the 

 finer stems of grasses. 



^[r. II. K. Dre.sser states that in the vicinity of ]\ratamoras these birds are 

 fond of fre(iuenting small villages, and that he fre(iuently Ibund their nests 

 within the gardens aud court-yards of the hou.scs, and near the road. 



The eggs of this Thrush vary considerably in size, ranging from 1.20 to 

 l.();5 inches in length, and from .84 to .77 of an inch in Itreadth. Their 

 mean length is 1.12 inches, and their average breadth .80. They hav(! 

 a light green ground-color, generally, though not thickly, covered with line 

 brown spots.

This very curious race S(>ems to unite the characters of ciirrirustris and 

 Iccoiitci ; in fact, it is so exactly intermediate between the two, that we are 

 abiiost in doubt as to which it is most ntiarly related. Having the stout form 

 and liirger size, as well as tiie spots on the abdomen, of the former, it has also 

 the uniform colors and general appearance of hroufrL Were it not that the 

 nest and egg.s, with the parent accompanying, had been receivt'd from Dr. 

 I'almer, we might be tempted to consider it a hybri.l between these two
