 Both sternum and pelvis rather broader than the type.

 The pelvis is much larger in proportion to the sternum than is usual in the family. 



Malueus, Vieill.

 The group in which the three following genera have been placed is rather an anomo- 

 lous one. I have doubts whether they ought not to be classified with the Motacillidce, 

 judging from the greater proportionate width of the sternum and pelvis in comparison 

 with the true Bylmadae. One genus, which has been usually classed with it, (Megalurus,) 

 differs materially from both in having a narrow sternum, less depth of keel, and also a 

 much narrower pelvis. I have, however, classed it with Malurus, although confident that 

 it is not its true place. None of the three genera that I have before me — Malurus, 

 Stipiturus, and Megalurus — have that bulbous appearance on each side of the ilium, 

 posterior to the acetabulum, common to the Motacellidce and true Sylriadce.
