free margins. The front border is truncate, sloping downwards and in- 

 wards ; and the hinder margin slopes downwards at once and forwards,, 

 and not partly outwards as in fig. 4. 



These differences in outline do not seem to be due to bad preservation, 

 for the ridges are truly concentric with the margins, as far as they are 

 exposed; but they are varietal, if not sexual. Hence fig. 5 may be 

 distinguished as var. Qreheana, after Herr Grebe, of the Prussian Geo- 

 logical Service, who found it crowded together with I]. Geinitzii. in the- 

 hard, dark-coloured Lebach shale from the railway tunnel near Boos, a 

 village about a kilometre from Miinster-on-the-Nahe. 



III. In Katzer's ' Geologic von Bohmen,' III. Abtheilung, 1892, the- 

 following fossil Phyllopoda are mentioned : — 



P. WQ'd, Esther ia cyanea, Fr., from Lubna ? (Lubno). 



P. 1156 ,, ^eweMa (Jordan), from Nvirschan (Nyfany), 1 Post-Car- 



P. 1156 „ sp., from Tfemosna, J boniferous. 



Since that date our friend Dr. Anton Fritsch has shown us some 

 figures of Phyllopods which probably comprise those referred to above. 

 These figures are, 1, an Esthena, from the lowest horizon of the Permian 

 system of Bohemia, in the bituminous shale of Nyran, near Pilsen ; 2, 

 E. cyanea, sp. nov., Pritsch, from the Middle Permian, in bituminous 

 shale from Kaunova ; 3, an Estheria, from Upper Permian bituminous 

 shale at Kastialov ; 4, an Estheria from the limestone with Palceonicus- 

 Vratislavensis of the Uppermost Permian at Braunau ; 5, an Estheria,. 

 also from the Uppermost Permian Limestone. These, with some Ostra- 

 codes, will be published in due course by Dr. A. Fritsch in his ' Fauna, 

 der Gaskohle,' some parts of which have been already issued. 



IV. S. S. Gorby, State Geologist, has issued some ' Advance Sheets 

 from the Eighteenth Report of the Geological Survey of Indiana,' 8vo,. 

 Indianapolis, September, 1892, in which the Paleontology is done by 

 S. A. Miller and S. A. Casseday (see p. 23). Some Phyllocaridce of 

 the family of Pinacaridce are treated of, and at p. 77, pi. 9, fig. 37, 

 the post-abdomen (trifid) of Mesothyra Gurleyi, n. sp., from the Kinder- 

 hook group, at Le Grand, Iowa, is described and illustrated ; and at 

 p. 78, pi. 9, figs. 43-46, Maerocaris Gorbyi, n, gen. et sp., from the 

 Keokuk group, at "West Point, Indiana. Of this latter form fig. 43 

 shows the interior of the carapace- valves and four abdominal segments. 

 Fig. 44 gives four and part of another abdominal segment, and the post- 

 abdomen slightly broken at the end. Fig. 45 is eight abdominal seg- 

 ments and the post-abdomen. Fig. 46 is a tooth, found in the same 

 rocks, that may possibly belong to the internal masticatory apparatus. 



V. In the ' Canadian Record of Science,' vol. v. No. 4, October, 

 1892, pp. 205-208, Mr. J. F. Whiteaves gives a ' Description of a new 

 Genus and Species of Phyllocarid Crustacea from the Middle Cambrian of 

 Mount Stephen.' The fossil is shown by a figure at p. 206, and named 

 Anomalocaris Canadensis, gen. et sp. nov. The diagram and description 

 do not make it appear to us to be a Phyllocarid. 



VI. Mr. Robert Etheridge, jun., in the ' Records of the Geological 

 Survey of New South Wales,' vol. iii. part 1, 1892, pp. 5-8, pi. 4, 

 describes and figures four specimens of the Hymenocaris Salteri, M'Coy,. 

 and states his belief that they belong to Lingulocaris ; and, as there is- 

 a L. Salteriana, he thinks that they should be called L. Maccoyii.
