' This large and indeed gigantic Ceratiocaris, represented by seven 
abdominal segments, with the caudal appendages of telson and two stylets, 
in the Ludlow Museum, has been described in the ‘Geol. Mag.’ for 
March 1871, and illustrated with a reduced figure. The carapace is there 
estimated as having probably been eight inches in length. The segments 
‘giving eight inches, and the telson being about nine inches in length, the 
animal would be more than two feet in total length. As pointed out in 
the paper referred to, the telson is certainly the longest known. Thus 
we find the relative proportions to be for C. Ludensis, H.W., 144; 
©. Murchisoni (Agass.) 128 (as defined above) ; C. Deweii (J. Hall), 100;

_’ The segments are ornamented along the back with imbricated or 
lattice-like raised angular lines, which pass downwards on the sides into 
oblique and then curved wrinkly lines, and these on some of the segments 
form an irregular reticulation at the anterior margin. The ultimate 
“segment is striated longitudinally with interrupted and inosculating lines. 
‘The spines are stout, tapering slowly, slightly curved inwards (down- 
wards), delicately ribbed, and bear close-set marks of the bases of small 
‘spines between or on some of the ridges. 
_ This fine specimen is imbedded in the greenish-grey, sandy, laminated 
mudstone of the Lower-Ludlow series, at Church Hill, Leintwardine, 
near Ludlow, with Graptolites. It was found by the late Mr. H. Pardoe, 
and is preserved in the Ludlow Museum.

Of the two species, so abundant in the Upper-Ludlow Shales of the 
Logan Water, near Lesmahago, in Lanarkshire, and described (unfor- 
tunately without good figures) by J. W. Salter in the ‘Ann. and Mag. 
Nat. Hist.’ for March 1860, we have examined many good specimens. 
mentioned by Salter, one (C. papilio) has the carapace more oblong 
than the other (C. stygia), which is deepened by a greater or less angu- 
larity on its ventral margin. In the woodcut diagrams at p. 154 of his
