some of those of Malnrus Icucopkriis ; hut the smaller size of the 

 •nest and stouter shape of the Emu-Wren's eggs enable them to 

 be readily separated by the collector. 



Calamanthus campestris hartogi, Carter {Bull. B.O.C., xxxvii., 

 p. (')), or Calamanthus campestris dorrei, Mathews. 



Nest. — Dome-shaped, with entrance very near the top, size 

 5 inches by 3 inches, substantially built of pieces of dried grass and 

 Iierbage ; lined with much finer shreds of the same materials : 

 placed on the ground under shelter of a low bush. 



Eggs. — Clutch three ; shell smooth and glossy : ground colour 

 pale chocolate-brown, with indistinct darker markings of the 

 same colour all over the shell, but forming a cap at the larger 

 end ; they approach closely in shade to the eggs of Calavianthiis 

 fiiHginosus. Taken 28th June, 1920. 



Dimensions in inches : — (a) .78 x .58, {b) .76 x .55, (c) .77 x .58. 



With the exception of those of Calamanthus isahelliniis, these 

 are the smallest eggs of the genus represented in my collection. 



Corvus bennetti bonhoti, Mathews. 



Nest. — A substantial structure of sticks lined with bark, and 

 placed low down in a dwarf eucalypt. 



Eggs. — Clutch six originally (one found broken in nest), of the 

 light-coloured variety of Corvus bennetti eggs of Western New South 

 Wales, the five specimens being fairly uniform in shade. 



Dimensions in inches : — (a) 1.65 x 1.07, (b) 1.71 x i.ii, (c) 1.68 x 

 I. II, {d) 1.63 X 1.08, (e) 1.64 X 1.08. Taken 5th August, 1920. 



Two other clutches of five and four eggs respective^, taken 

 from a nest built on a windmill stand (see illustration), are slightly 

 smaller than those described above, and are extremely irregular 

 in colour, no two eggs resembling one another. Laid by the same 

 bird and from the same nest ; the clutches were taken 14th July 

 and 6th August. A third clutch was allowed to hatch out. 



The skins accompanying the eggs are evidently those of the 

 Short-billed species. Mr. Carter calls the Dirk Hartog Crow 

 Corvus coronoides, while Mr. Whitlock describes it simply as the 

 " common Crow of the island."* 



The two following may perhaps be considered doubtful sub- 

 species : — 



Oreoica cristata lloydi, Carter [IJiis, 1917, }). ()o8). 



Nest. — The usual substantial Oreoica t\-pe, ])laced low down 

 in a large bush. 



Eggs. — Clutch four, taken 2()th August, 1920 ; ground colour 

 pale greenish-blue, tliickly covered with small (almost circular) 

 spots of brownish-black. Size in inches of an average specimen, 

 1.06 X .78. 



*, Recently {Bull. B.O.C.. xl.. p. 76) Mr. G. M. Mathews has described this 

 Crow as C. cecilce- hartogi, comparing it with C c. marugli. It would assist 

 students better, perhaps, were new sub-species compared with typical 

 birds, which are often more accessible than later named sub-species. — Eds.
