354 //. Woodward — British Fossil Crustacea, 



I have little doubt in referring this to Hermann von Meyer's 

 Glyphea g ranch's,^ (since placed by Oppel in his genus of Pseudo- 

 ghjphea,)' from tlie Lias of Tubingen. Tlie carapace, which is finely 

 granulated, measures two inches in extreme length, and nine lines in 

 gi'eatest breadth of side. Two nearly parallel furrows pass from the 

 dorsal line obli(|uely across the side of tlie carapace, separating the 

 branchial from the cardiac region, and terminating in a smooth 

 rounded prominence on tlie hepatic region. The nuchal furrow, 

 between the cardiac and gastric regions, is short and deeply indented ; 

 the frontal portion of the carapace is marked by two lines of small 

 tubercles, converging towards the rostrum, which is short, but 

 pointed (as in Astacus) ; the orbits are sliallow. The abdomen is 

 IJ inch in length, the segments are granulated like tlie cepha- 

 lothorax, the epimera are falcate and finely serrated upon their 

 posterior borders. The plates of the telson are 7 lines in length and 

 4 lines in breadth; the exterior plate is divided near the lower 

 margin by an oblique suture as in Astacus and Homarus. The long 

 and slender walking legs can be seen imperfectly preserved, but their 

 terminations are not visible. The anterior pair of legs M^ere chelate 

 but the evidence of this is derived from other examples. 



I have already alluded to this example^ as the Pseiidoglyphea Win- 

 woodi, sp. nov., but, after a further examination, lam obliged to refer 

 it to II. von Meyer's species, P. grandis, which, although founded 

 upon a less perfect example than that figured in our plate, appears 

 nevertheless to be identical. 



The following species of FseudoglypJiea have been enumerated by 

 Dr. Oppel : — 



Pseiidoglyphea grandis, Meyer, sp. Lr. Lias, Tubingen ; Weston. 

 „ Ettaloni, Oppel, M. Lias, Pegney and Chalindrey. 



„ amaltliea, Oppel, M. Lias, Boll, Wurtemberg. 



„ stricta, Etallon, U. Lias, Corlee, Normandy. 



„ eximia, Oppel, Oxfordian, Dept. Meurthe. 



„ Terquemi, Oppel, Oxfordian, Dept. Meurthe. 



To this genus must also be referred the Astacus Birdii, of Bean, 

 MS. from the Inferior Oolite, Peak, Yorkshire, and four other cara- 

 paces (to be hereafter figured), 1. from the Oolite beds, railway 

 cutting, near Stamford, collected by Prof. Morris, (Mus. Brit.) ; 2. 

 from the Lower Lias, Northampton, collection of Samuel Sharp, Esq., 

 r.S.A., r.G.S. ; 3. from the OoHte of Shotover, collected by W. 

 Cunnington, Esq., F.G.S., (Mus. Brit.) ; 4. Middle Lias, Dundas, 

 near Bath, collection of C. Moore, Esq., E.G.S. Two chelae, from the 

 Cornbrash of Chippenham, probablj^ also belong to this genus, but 

 more evidence is needed liefore the species can be safely determined. 



V. The detached cephalothorax (Plate XVII. Fig. 2) is referable to 

 the genus Glypliea, as restricted by Dr. Oppel.* It was obtained by
