sharp tubercles directed forward. The second line is inter- 
rupted in the middle. The third and fourth segments have 
neither the furrows nor the lines. 
In 1850 Dixon (Geol. & Foss. of Sussex, p. xv, pl. xxxviil.* 
fig. 8) published a figure of part of the cephalothorax of a 
Crustacean, which appears to belong to a Gilyphea. It is 
from the Cretaceous beds of Sussex. In the same year H. 
von Meyer (Paleont. i. p. 141) described, under the name of 
Selenisca gratiosa, a fossil Crustacean from a deposit of the 
age of the Solenhofen Limestone at Wurmlingen, near 
Tuttlingen, in Wiirttemberg. He regarded it as allied to 
Glyphea. 
In 1851, in his ‘ Lethea geognostica’ (iv. p. 423), Bronn 
described the Glyphee as having the anterior limbs termi- 
nated by pincers. This is an error, probably due to Phillips 
(see Jameson’s Edinb. Journ. xix. p. 372) ; but he adds that 
we must not confound the genus Glyphea, Meyer, 1835, 
with the synonymous genus of Minster, 1839, for the latter 
of which Meyer, in 1840, proposed the name of Hryma. 
Pictet (Traité de Pal. 1. p. 450), in 1854, seems to have 
copied Bronn’s error. 
In 1858 Quenstedt mentions Glyphea grandis from the 
Lower Lias of Frittlingen as probably identical with Meco- 
chirus grandis (Der Jura, p. 88). He also (p. 200) mentions 
a G. Amalthet, known only from portions of the pincers (which 
may belong to G. liasina, Meyer), and a G. numismalis, 
Oppel, which is larger and came from the Numismalis marls 
of Hinterweiler, south of Tubingen (p. 349). Afterwards 
(p. 891) he describes a pincer found in an iron-mine at Aalen, 
under the name of G. aalensis, and adds that he adopted the 
name G'lyphea because it was then in vogue, forgetting appa- 
rently that the Glyphee are monodactyle. Elsewhere (p. 549) 
_ he refers to the Astacine Crustacea, of which the cephalo- 
thorax has two transverse grooves instead of one as in the 
existing genera; and for this reason, he says, von Meyer gave 
them the name of Glyphea and afterwards that of Klytia. 
He figures Glyphea bedella (pl. lui. fig. 5) from Balingen, 
which he regards as having most analogy with Klytva 
ventrosa of the White Jura. In his description of the 
Brown Jura (p. 807), Quenstedt refers to some Crustacea 
from this formation, which he names Glyphea ornati, G. 
Mandelslohi, and Orphnea ornata. The first two have 
didactyle pincers, and are not Glyphee. With regard to 
his Orphnea ornata he says, “In the ‘ Handbuch der 
Petrefactenkunde,’ p. 269, it is shown that von Miinster’s 
genus has as its type Palinurus Regleyanus, Desm., from the 
terrain 4 chailles,’ and Macrourttes pseudoscyllarus, Schloth.
