866 NOTES AND EXHIBITS. 



after a period of growth in New South Wales, the wool of the 

 same ram reverted to the original type of the pure Merino. The 

 contrast between the two samples was clue simply to the effects 

 produced by the differences in the climate, soil, and culture. 



Dr. von Lendenfeld exhibited a specimen of Haliphysema 

 suberites, nov. spec, obtained from Macrocystis in Port Jackson. 

 This Haliphysema is in appearance somewhat similar to H. 

 ramulosa. The skeleton of the hollow stem consists of truncate 

 longitudinally disposed spicules. Similar spicules with bulbous 

 centripetal ends are found in the spherical body ; these are situated 

 radially. In the stem, sand-particles are found, which protrude two- 

 thirds of their length. Dr. Lendenfeld was inclined to consider 

 the spicules to be produced, and not collected by the Haliphysema. 



E. P. Ramsay exhibited the new birds described in his Paper. 

 Also specimens of Halcyon drops from various localities, and a rare 

 species of Coriphilus, C. Kuhlii, peculiar to the Fanning Islands. 



Mr. Brazier exhibited the following species of Helicidce in con- 

 nection with his Papers : — Helix Broadbentii, Braz. ; H. (Obba) 

 Goldiei, Braz. ; H. (Geotrochus) Zeno, Braz. ; H. (Geotrochus) 

 Tapperonii, Smith ; H. (Geotrochus) Tayloriana, Ad. and Reeve ; 

 H. (Spluerosjnna) Gerrardi, E. A. Smith ; H. ( Planispina) corni- 

 culum, Hombr. and Jacq. ; Nanina (Xesta) citrina, Linn. 



Mr. Fletcher exhibited a number of very old and rare publica- 

 tions referred to in his list of works on the Marsupialia and 

 Monotremata.
