A single species, of abnormal colouring for this group of the Ty- 

 rannidce, but usually referred here, forms the type and only known 

 specks of Sisopygis, so called from its superficial resemblance to 

 Motacilla. Sisopygis builds in bushes, makes an open nest, and lays 

 3 or 4 white eggs spotted, mostly at the larger end, with reddish 

 {d'Orb.).
