1 The earliest name for this specie- (Lalage terat Auct.) is without doubt 

 Turdus dominicus Midler (Natursyst., Suppl., 1776, p. 145). but this is pre- 

 occupied by Turdus dominicus Linnaeus (Syst. Nat., ed. 12, Vol. 1, 1766, p. 

 295), which is Mimus polyglottos dominicus. The next available specific term 

 is Turdus niger Forster (Indische Zool., 1781, p. 41), which antedates Turdus 

 terat Boddaert (Tabl. Planch. Enlum., 17S3. p. 17) ; and the species should 

 therefore stand as Lalage nigra (Forster I. 



2 This is the original spelling of the specific name.
