belong to the genus Ghjphea, and is from the collection of E. F. 

 Tomes, Esq., who obtained it from the Lower Lias (zone of Am- 

 monites semicosialus) . VVelford Hill, Stratford-on-Avon, Warwickshire. 



The specimen exhibits the dorsal aspect in almost a perfect state ; 

 and is 2 inches in extreme length, of which the carapace measures 

 11 lines, the abdominal segments 9 lines, and the telson 4 lines. 



The rostrum is 1 line in length ; the carapace is strongly indented 

 by the nuchal furrow 5 lines from its frontal border, the part anterior 

 to the nuchal furrow being ornamented by two parallel lines of small 

 tubercles on each side of the rostrum, the interspaces being smooth. 



Two furrows, not differing greatly in position from those on the 

 carapace of Glyphea rostrata, divide the cardiac and branchial regions, 

 the surface of which is thickly studded with minute tubercles. The 

 legs are slender and appear to be monodactylous. The epimera of 

 the abdominal segments are obtuse and have a raised border ; the 

 surface of the segments was smooth and destitute of punctae or 

 tubercles. The lamina of the tail are broad, and the exterior plate 

 is divided transversely near its extremity by a line of suture, as 

 already described in the genus PsendoglypJiea. 



This elegant little crustacean cannot be referred to any published 

 species with which I am acquainted ; it nearly approaches the 

 Glyphea Miinsteri, of Voltz, from the Oxfordian of St. Scolasse, but 

 they do not agree together in the divisions of the carapace ; nor can 

 it be referred to the G. rostrata, of Phillips. I have, therefore, 

 fore, much pleasure in naming it Glyphea Tomesii, after the discoverer, 

 K. F. Tomes, Esq.

V. — Note by Professor Morris, F.G.S., on Organic Eemains in 

 THE Somersetshire Coal-field. 



THE occurrence of invertebrate animal-remains in the Somersetshire 

 Coal-field has not, I believe, been very frequently noticed. With 

 the view of drawing attention to the subject, I send a brief notice of a 

 few remains which I had the pleasure of collecting during a visit 

 with Mr. J. Prestwich to this district, hoping that the local geologists, 

 or members of the Natural flistory Societies, may be induced to 

 record the observations they have made, or further prosecute 

 enquiries into the occurrence of the animal-remains, either verte- 

 brate or invertebrate, which may be associated with the rich and 

 interesting flora of this Coal-field. Casts of bivalve mollusca 

 {Anthracoptera ?) were detected in the coal-shale at Twerton, near
