of Australian ])irds^ and was figured in the Watling drawings, 

 whence Latham described it as Muscicapa crepitans. But lie 

 had already named it Corvus oUvaceus, or White-cheeked 

 Crow, so the latter name is here shown to have priority. 

 There are six subspecies, and a second species has been 

 separated from south-west Australia which may be extinct, 

 but it would not be right to be too certain of this, in view 

 of its peculiar haunts. It may be remarked that the exact 

 position of the Coachwhip-bird in our list is quite uncertain, 

 but tills may be said of several species given in the present 

 instalment. 



Again the reader must be asked to study the life-histories 

 of the gregarious Babblers {Pomatorhmus and Morganornis), 

 often called Cat-birds or Twelve Apostles, and learu of their 

 curious stick nests — often used communally: one species is 

 allotted to the former and two to the latter, with fifteen 

 subspecies in all ; but we are asked to note that Tardus 

 frivolus (Latham ex Watling) is not synonymous wuth 

 either. The '^ Field Wrens " come next, where the habits 

 are once more a great consideration. Calamanthus monta- 

 nellus of Milligan should perhaps be specifically separated 

 from C. fuliginosus with a subspecies ashbyi, but p. 287 

 must be read to understand the whole position. Then 

 Calamanthus campestris constitutes a new subgenus, Ere- 

 mianthus, and finally we finish with four races of the 

 Migratory Song-Lark {Cine lor hamphus).
