NOTES AND EXHIBITS. 



Mr, Hedle}'' shewed examples of the rare Carrier-Trochus 

 i^Xenophora) dredged off the coast of Netv Zealand b}' Captain 

 BoUons of the Government steamer " Hinemoa." 



Mr. David G. Stead exhibited and recorded us an addition to 

 the fish-fauna of New South Wales, a specimen of the remarkable 

 fish known as the " Moorish Idol," Zancliis cornutus (Linn.). This 

 fish is looked upon as a tropical species; and its occurrence on 

 this coast so far south as Botany Bay (where the example 

 exhibited was obtained) is, therefore, of some interest. 



Mr. Cambage exhibited herbarium specimens, timber, bark, oil 

 and seedling plants in illustration of his paper describing a new 

 species of Eucalyptus (^E, parvifolia). 



Mr. Rainbow sent, for exhibition, a living and also a preserved 

 example (9) of an aquatic spider, Dolomedes facetiis, L.K., from 

 Duck Creek, near Clyde. This exceedingly pretty spider is chiefly 

 interesting from the fact that it lives under water. It constructs 

 an irregular web amongst weeds or stones in stagnant or sluggish 

 waters. The body of the animal is densely clothed with *'down " 

 which not only enables it to collect sufficient air, so that it may 

 remain submerged for hours, but also keeps the body dry. It 

 cannot dive like the " diving-bell " spider of Europe, but when 

 it descends below the surface-film it has to pull itself under by 

 grasping stems or leaves of plants. When disturbed, it comes to 

 the surface of the water, over which it skates rapidly in quest of 

 a place of safety. The species was described and figured by 

 Koch in " Die Arachniden Australiens " (B. ii., p. 869, T. Ixxiv., 

 figs 5-6). The figures are indifferent, the legs being shown far 

 too long and tapering; the head too sharply truncated in front; 

 and the colour-pattern ill defined. The species has a wide range, 

 from Rockhampton to Sydney; it also occurs in New Zealand and
