682 NOTES AND EXHIBITS. 



Mr. F. Ratte also exhibited Calcareous Shells of insects allied to 

 those exhibited at the last meeting, by Mr. C. S. Wilkinson, 

 but elongated and conical, instead of helix-shaped. Of these, 

 at least two different shapes can be distinguished. (1.) One 

 ornamented with two longitudinal ribs and irregular tubercles 

 formed by some foldings or denticulations of the outside layers of 

 growth of the shell. (2.) One smooth, with only circular lines of 

 growth, longer than the first, being about 2 centimeters in length ; 

 and another smooth, one much smaller. The larva is growing at 

 the present time on some species of Eucalyptus. It is provided 

 with an elongated forehead, very dark eyes, and a thin tongue 

 working in a tube or sheath reflected downwards. The tarsi are 

 two-jointed, as far as can be seen in the state of larva. He believed, 

 that it derives the calcareous matter for building the shell from the 

 sap of the tree. It constantly emits water like some species of 

 Aphrcphora. This larva is provided at the hind part of its body 

 with a chitinous operculum which is removed after it has under- 

 gone one of its last changes. He also exhibited females of 

 Monophlebus attacked by a red fungus. One of these was 

 growing on the living insect. 



Dr. Cox exhibited a sample of a very rare shell, Latiaxis Mawce 

 of Gray. Latiastis is a sub-genus of Eapana of Klein, characterized 

 by the whorls being more or less detached, and carinated, the 

 aperture small, trigonal, the canal narrow, rather long and curved. 

 The operculum has been hitherto unknown, but the specimen 

 exhibited showed the operculum perfect. It is a very distorted 

 shell of a rare occurrence, found on Coral Reefs and supposed to 

 live on the coral polyps. It is closely connected with the common 

 American Tertiary fossil Fusus quadricostatus. 



Mr Macleay exhibited specimens of Dipsas Boyclii and Diemenia 

 atra, the two snakes described in his paper. Also a specimen of a 

 new species of Furina, received by Mr. Ramsay from the Barrier 

 Ranges, which he said he would describe on a future occasion. 



Dr. R von Lendenfeld directed the attention of the meeting to 

 the recently reported death of Dr. Hochstetter, the well-known 

 Austrian traveller and geologist, and gave a brief sketch of his 

 life and work.
