XIX. — Description of the Nest and E(jgs of Mirafra rufii)il< a 

 {Rufous-headed Lark). By Lieut. Stanley Pershousk, 

 2nd Border Regt. 



At Middelburg, Transvaal, on the 11th November, 1905, 

 I found the nest of the Rufous-headed Lark (Mirafra 

 rufipilea). The parent bird was snared on the nest and 

 identified by Mr. W. L. Sclater, M.A., of the South African 

 Museum. The nest, which was made of coarse grass and 

 lined with finer grass, dome-shaped, was sunk about two 

 inches in the ground, under a tuft of grass, quite close to a 

 cart-road. Some of the grass-stems of the tuft were pulled 

 over and woven into the nest. It contained two white 

 elongated eggs, thickly spotted with brown and rusty brown, 

 forming almost a brown patch on the obtuse ends. They 

 were incubated and I was unable to blow them.

 Portions of a Bird's Anatomy. By Professor Anton 

 Reichenow. Translated for this Journal by Mr. Henrik 

 Gronvold from the original paper (Orn. Monats., March

It is of considerable importance for any person who may 

 have to identify Birds from written descriptions to be 

 acquainted with the correct names of the different parts of a 

 Bird's body. 



At the present day, more than in former times, the Col- 

 lector, Traveller, and Field-Naturalist all have both the 

 opportunity and wish to describe new forms. 



Even if the accurate naming of the special characteristics 

 of a Bird was only of importance to the describer of a new 

 form, it is still clearly necessary that his description should 

 be generally intelligible. On account of this, and for the
