mass of muscular fibres, which are scarcely capable of being divided 

 into distinct portions, although three pairs may be in some degree 

 traced, an anterior, a middle, and a posterior. These muscles are simi- 

 larly formed in all the other birds of this family, the Musicapince, de- 

 scribed in this work. 



OLIVE-SIDED FLYCATCHER. 



MUSICAPA COOPERI, NuTTALL. 

 PLATE CLXXIV. Vol. II. p. 422. 



This species has never been observed in South Carolina, although I 

 met with it in Georgia, as well as in the Texas, in the month of April. 

 According to Mr Nuttall, it is " a common inhabitant of the dark fir 

 woods of the Columbia, where they arrive towards the close of May. 

 We again heard," he continues, " at intervals, the same curious call, 

 like ''ffk-p/iehea, and sometimes like the guttiu"al sound of jo h p-phebee, 

 commencing with a sort of suppressed chuck ; at other times the notes 

 varied into a lively and sometimes quick jt) t-petoway. This no doubt 

 is the note which Wilson attributed to the Wood Pewee. When ap- 

 proached, as usual, or when calling, we heard the j9«<jo«jo«." A single 

 specimen was shot on the banks of the Saskatchewan, and has been de- 

 scribed in the Fauna Boreali- Americana under the name of Tyrannus 

 horealis. 



Dr Beewer has sent me the following note : — " A female specimen 

 obtained by me measures 6^ inches in length, being fully half an inch 

 shorter than the male. Nape of the neck, belly, vent, throat, and 

 flanks white ; in the latter, continued to the back, so as to be visible 

 above the fold of the wings ; a broad olive band across the breast ; in 

 all other respects it resembles the male. A nest, which 1 have exa- 

 mined, measures five inches in external diameter, and three and a half 

 inches in internal, and is about half an inch deep. It is composed 

 entirely of roots and fibres of moss. It is, moreover, very rudely con- 

 structed, and is almost wholly flat, resembling the nest of no other 

 Flycatcher I have seen, but having some similitude to that of the 

 Cuckoo."
