IV. — On a jN t ew Species of Ehyon from the Upper Lias, 

 Dumblexon Hill. 



By Henry Woodward, LL.D., F.R.S. 



VARIOUS forms of Macrourous Decapod Crustacea referable to the 

 genus Eryon have attracted my attention from an early date. 1 

 and in the Geological Magazine for 1888 2 I gave a summary of all 

 the then known species. The following seven species are British : — 



Eryon (Coleia) antiquus, Broderip, sp., 1840. Lower Lias, Lyme Regis. 



E. Barrovensis, M'Coy, 1849. Lias, Barrow-on-Soar. 



E. Brodiei, H. Woodw., 1866. Lower Lias, Lyme Eegis. 



E. crassichelis, H. Woodw., 1866. Lower Lias, Lyme Regis. 



E. Wihncotensis, H. Woodw., 1866. Lower Lias, Wilmcote. 



E. Moorei, H. Woodw., 1866. Upper White Lias, Ilmmster. 



E. Stocldarti, H. Woodw., 1881. Stonesfield Slate, Oxfordshire. 



The sixteen species given below are all foreign : — 



Eryon Escheri, Oppel, 1862. Lower Lias, Schambelen, Switzerland. 



E. Edivardsi, Moriere, 1864. Upper Lias, Calvados. 



E. Calvadosi, Moriere, 1883. Upper Lias, Calvados. 



E. Hartmanni, v. Meyer, 1862. Upper Lias, Boll, Wurtemberg. 



E. Perroni, Etallon, 1858. Oxfordian, Haute Saone. 



E. arctiformis, Sehlot., 1820. ^ 



E. bilobatus, Miinst., 1839. 



E. elongatus, Miinst., 1839. 



E. longipes, Fraas, 1855. 



E. Oppeli, H. Woodw., 1866. 



E. orbiculatus, Miinst., 1839. 



E. projrinquus, Sehlot., 1822. 



E. Redenbacheri, Miinst., 1839. 



E. Sclmberti, v. Meyer, 1836. 



E. spinimanus, Germar, 1827. 



E. Neocomiensis, H. Woodw., 1881. Lower Cretaceous, Silesia. 



I have recently received from Mr. Linsdall Richardson, F.R.S.E., 

 F.G.S., the Honorary Secretary of the Cotteswold Naturalists' Field 

 Club, Cheltenham, a specimen of Eryon from the Upper Lias of 

 Durnbleton Hill, near Beckford, Gloucestershire (see Fig. 2), which 

 appears to represent a species of that genus new to this country, but 

 closely allied to a small group comprising three species, namely, 

 Eryon propinquus, Sehlot., sp., E. oroicidatus, Miinst., &n&E. elonyatus, 

 Miinst., all from the Lithographic Stone of Solenhofen, in Bavaria, 

 and of Kimmeridgian age, characterized by the more rounded form of 

 their carapaces when compared with such species as E. Barrovensis, 

 M'Coy, E. Brodiei, H. Woodw., E. antiquus, Broderip, sp., and 

 E. arctiformis, Sehlot., sp. 



We subjoin a figure of the under-side of Eryon propinquus, Sehlot., 

 sp. (Fig. 1), from the Lithographic Stone of Mornsheim, near 

 Solenhofen, Bavaria (see Oppel's Pal. MiWheil., 1862, tab. i, fig. 2). 

 In this specimen all the appendages are most beautifully preserved — 

 indeed, quite as well as in a living form. Two specimens, almost 

 equally perfect, may be seen in the Haberlein Collection, also from 

 the Lithographic Stone of Solenhofen, in the British Museum (iSTat. 

 Hist.), Department Geology, Gallery VIII, Wall-case Crustacea.
