of wing and tail quills blackish, first feather of the primaries all

Ortygometra quadristrigata and Porzana tabuensis. from the 

 Samoan Islands. There are also specimens of Ardea sacra 

 and Phaeton eethereus, of which latter I give the following

EXHIBITS. 



Mr. Brazier exhibited specimens of Haliotis Oaniliculata, a 

 species not previously fouud in Port Jackson ; also of Tellina 

 perna, from the same locality, and a collection of small shells, 

 showing a convenient way of displaying them. 



Mr. Masters exhibited a large number of Spiders, beautifully 

 mounted on glass slides, enclosed in glass tubes filled with clear 

 spirits of wine. The specimens were affixed to the slides by 

 ordinary clear gum, which rapidly hardens in spirits. The 

 advantage claimed for this process of mounting is not only 

 the improved appearance of the specimens, but the facility with 

 which the most minute anatomical details may be examined under 

 the microscope, without the necessity of removing the specimens 

 from the slide or tube.
