raised, how should these Eucjilypts be distinguished by name ? 

 Another instance brought forward was that of E. Sieberiana, 

 as botanists would call it, from different localities. Messrs^ 

 Baker and Smith contended that in such cases it is almost, 

 if not quite, impossible to specifically determine botanical material 

 without the aid of chemistry. Discussion followed. 



Mr. W. J. Rainbow exhibited, by kind permission of the 

 Curator of the Australian Museum, a living specimen of the 

 beautiful spider Dic7-ostichus maynificus, together with one of its^ 

 " egg-l^ags " or cocoons. This species was described and figured, 

 from a spirit specimen, in the Proceedings for 1897 (pp. 523-4, 

 pi. xvii. figs. 8, 8a, 86, and the nest and egg-bags were figured in 

 the text on pages 537 and 538). In addition to the yellow 

 patches on the abdomen mentioned in the description, it is now 

 to be noticed that the animal has, when alive, a group of large 

 red spots in front, and at the centre a series of small red spots 

 and markings. 



Mr. Froggatt exhibited a shoe-horn destroyed by the larvje of 

 the "Museum beetle" (Anthrenus); and a collection of the cocoons 

 of an apparently undescribed case-moth ( Entometa sp.) upon a 

 piece of the central portion of a hollow tree from North Queens- 

 land. The cocoons are covered with sand and grass stalks. 



Mr. Stead exhibited a series of beautifully mounted Port 

 Jackson Crustaceans and their appendages, and gave a brief 

 description of the habits of the animals. The following species 

 were represented : — Graj^s^is variegatus, Latr.; Plagusia chahrus, 

 Miers; P. glabra, Dana; Ozius truncatus, M.-Edw.; C hasmagnathus 

 Icevis, Dana; Leptodius exaratus, M.-Edw.; Mycteris longicariyuSy 

 Latr.; Hekecius cordi/ormis, Dana; and Petrolisthes.
