NOTES AND EXHIBITS. 



The President exhibited a spoon of native manufacture, recently- 

 brought from the Solomon Islands by Count Morner. 



Mr. D. G. Stead showed specimens of the common " Drill or 

 Boring Whelk" {Trophon i:)aivcfi)^ and he described its depreda- 

 tions upon oysters. He also exhibited the denuded tests of a 

 remarkable and very variable, flat. South American echinoderm, 

 Encope emarginata (Leske), obtained from sand-ballast, discharged 

 from a barque at Newcastle, N.S.W. 



Mr. E. J. Goddard exhibited a sample of water from a fresh- 

 water aquarium, swarming with a relatively large, ciliate infu- 

 sorian {Spirostomuiii sp.), from 2'5-3 mm. in length : a mounted 

 specimen of a marine leech, Branchellion sp., from the neck 

 of a turtle, with only 7 or 8 pairs of foliaceous branchiae 

 instead of the more usual number, 30-33 pairs ; t)ie species 

 was figured by Dr. MacDonald in Trans. Linn. Soc. London, 

 Zool. (2), i , p. 211, PL xxxiv., 1876, but without description : an 

 example of an undescribed species of Branchellion allied to B. 

 torpedhiis of European seas : and certain minute structures 

 occurring in an iri'egular manner over the neck of a species of 

 Pontobdella, which vvere regarded as spermatophores by 

 MacDonald, but which more probably represent the stalks of a 

 solitary endoproctous polyzoon, as they contain an abundant 

 musculature 



Mr. John Mitchell, of Newcastle, sent, for exhibition, two 

 valves of a fossil crustacean [Estheria^^.), with the following Note 

 on their occurrence in the Newcastle and Illawarra Coal-Measures: 

 " Recently I liave found a number of valves of the Phyllopod, 

 Estheria sp., in a very good state of preservation, in a thin band 

 of clay-ironstone, about 15 feet below the seam of coal locally 

 known as the Dirty Seam (No. 3 Seam from the surface at 

 Shepherd's Hill, and in the Merewether Beach Cliff) and about 

 on the same horizon as that from which I had previously obtained
