PLATE CL. 



nightingale; and indeed refembles it fo nearly, that the bird Is faicf, 

 on that account, to have obtained a name on the continent, fynony- 

 iHous with the enghfh epithet of Mock^ or Baftard Nightingale. 



In reverting to the authors quoted in our lift of fynonyms, it will 

 be perceived, that the lateft writers on this fubjefcl:, confider the 

 Pettychaps as a variety of the Linnaean Motacilla hortenfis. That 

 we cannot be miftaken as to the true Pettychaps, is fufficiently de- 

 monftrated, and with the individual fpecimens originally defcribed be- 

 fore us, we muft be allowed to (ju^lify our acquiefcence to the popu- 

 lar opinion^ with at leaft fo much hefitation as to leave it a matter of 

 opinion for future confideration, whether they are really the fame or 

 not. Dr. Latham had his doubts on the fubje^l formerly; thofe 

 on our mind are not obliterated, we are fiill inclined to think the two 

 ^irds may be fpecifically diflin6l# 



The difference of thefe birds is obvious in their general appearance: 

 the plumage in hortenfis is greyifli, or afh-coloured brown ; that of 

 the Greater Pettychaps, brown, tinged with greenifh : in hortenfis^ 

 the mandible is black, with the bafe of the lower one paler, in the 

 latter the bill is brown. Motacilla hortenfis, according to the plate 

 in Buffon, [FL Enh 579.) has a white fpot between the bill and the 

 eye, defcribed fometimes as a ftreak : and there is a faint whitifh mark 

 over the eye of the Pettychaps, which is, however, more inconfpicu- 

 bus. Befides fome difference in colour of the quill leathers there is 

 a material diftindlion in the character of the tail ; the latter being 

 uniformly dufky brown, while in the tail of hortenfis, the exterior 

 feather on each fide is white on the outer web, and marked on the 

 inner web, near the tip, with a dirty white fpot.
