 "This ground-bird is only found inlaud, in high country. It 

 has a long plaintive note in calling, which, wlien imitated, brings 

 him towards one. He then stalks to and fro, with tail erect and 

 spread, challenging the intruder. When disturbed he will fly 

 into low trees and bushes, but is quickly away again. The nest 

 is composed of a few twigs, scraped together at the foot of a 

 large tree in a sequestered place." {_A. G.'] 



The eggs sent by Mr. Groldie, two in number, were, as might 

 have been expected, pure white.

 yellow, but dark brown in front ; bare skin about the head livid, 

 like Common Turkey. When obtained, the skin was light, with 

 yellow, pinkish, and blue colours (faint) about it. These birds 

 were obtained in exceedingly rough country, and flew into a low 

 tree when disturbed. The nest is, like that of the Common 

 Turkey, composed of leaves, but smaller, being only about 6 feet 

 in diameter and 3 feet in height." \_A. G.'\

[Read June 15, 1882.]| 



Plettrechinus, a genus of the Temnopleuridse, was established 

 by L. Agassiz, in his monograph on the 'Echinodermes Scutelles,* 

 in 1841. It included the species Pleurechinus hothryoides, Agass. 

 (1841) ; and the following is the diagnosis of the genus given in 

 the 'Eevision of the Echini ' (p. 464) by Alexander Agassiz : — 

 " Echini resembling Temnopleurus, but having a more ovoid 

 outline, with simple pores arranged in straight or undulating 

 lines. Actinostome small, scarcely cut. Tubercles imperforate.
