29*^ June, 18S7. — The following papers were read: — 1) On a Tri- 

 lobite from Reefton N. Z., new to Australasia. By Professor F. W. Hutton, 

 F.G.S. The Trilobite here described is a species oî Homalonoius very closely 

 resembling, and perhaps identical with, H. Herschelii, Murchison, from S. 

 Africa, described and figured by Mr. Salter (Trans. Geol. Soc. [2], VII. 

 p. 215, pi. 24, f. 1-7). The greatest breadth of the specimen is 3-25 inches, 

 total length was probably about 8 in. or even more. It belongs to a group 

 highly characteristic of the Lower Devonian, and it appears to be new to 

 New Zealand. — 2) Botanical. — 3) Notes on Australian Land-Planarians, 

 with descriptions of some new species. By J. J. Fletcher, M.A., B.Sc, 

 and A. G. Hamilton. By systematically collecting Planarians in the neigh- 

 bourhoods where the authors are resident, or in localities visited during 

 vacation trips, they have, in the course of eighteen months, acquired suffi- 

 cient material to give in this paper descriptions of fourteen new species, 

 none of which however belong to the Australian genus Cœnoplana of Mose- 

 ley. Six of the new species are characterized by the possession of two eyes, 

 and, pending histological investigation, are referred to the genus Rhyncho- 

 demus of Leidy, hitherto unkown from Australia. The others are species of 

 Geoplana, F. Müll. In addition to these, two other species have been fre- 

 quently met with, which agree exactly with the descriptions of C. cœridea 

 and C. subviridis of Moseley, except that, instead of eyes being absent from 

 the anterior extremity, there is a single closely set row of them extending 

 right round it, connecting the crowded patches, one on each side, substan- 

 tially the same as Moseley himself describes in the New Zealand Geoplana 

 Traversa. Hence the authors conclude that Mr. Moseley, probably from an 

 indifi'erent or insufficient supply of material, overlooked the presence of 

 these eyes ; and they therefore propose to do away with Cœnoplana as a 

 separate genus, and to merge it in Geoplana. The third species described by 

 Moseley has not yet been met with. Bemarks are made upon the habits and 

 distribution of the species described, and as they have all been obtained 

 from a relatively very small area of this colony, there is every reason to sup- 

 pose that further search will prove this section of our fauna to be a very rich 

 one. — 4) On the Insects of the Cairns District, Northern Queensland. By 

 William Macleay, F.L.S., &c. This is the continuation of a Paper read at 

 the last meeting of the Society. The new species described are of the fami- 

 lies Tenebrionidce . Cistelidœ, Lagy-iidœ, Mordellidœ^ Rhipiphoridœ, Pedilidœ, 

 Cantharidœ, Oedemeridœ. and Erotylidœ\ in ail 45 species. — 5) 6) 7) Bac- 

 teriological and Botanical. — 8) Notes on some Australian Polyzoa. By T. 

 "Whitelegge. This paper deals with the following species: — Liinulites 

 cancellata, Busk, L. Philippinensis, Busk, Conescharellina depressa., Hasw., 

 Cupularia crassa, Tenison-ÄVoods, Limtdites angulopora, Ten.-Wds., (= C. 

 cornea, Hasw., = L. incisa, Hincks), Eschara xmibonata, Haswell, and a 

 species from Port Jackson which Mr. A. W. Waters thinks may be identical 

 with Flabellopora elegans, d'Orb. It is shown that the species have nothing 

 in common with the family SeUnarxdce to which most of them have been
