impressions ; crushed laterally, and showing the whole half from the. 
dorsal ridge to the epimeral border. In shape they are not unlike 
those of C. Scharyi, Barrande. They are ornamented with a strong 
leaf-like lattice-pattern, as in that species. The apices of some of the 
triangles thicken and form a kind of elongate drop-like ornament 
(Pl. VI. Fig. 16). The smaller (secondary) lattice-work inside each 
leaf-mark is not so distinct as in Barrande’s fig. 27. 
In hard blue micaceous shale (Ludlow Series), from the lake 
Ringsjon, Scania. 
This specimen is a portion of “fig. 1” in Angelin’s unpublished 
“Tab. B.” That figure shows a ‘large portion of the ultimate 
segment, and the complete penultimate segment; but the former 
and a third of the latter have been broken away, and a fracture 
passes between the two next segments.

1887. Ceratiocaris pectinata, sp. nov. Fifth Report, etc. p. 3. 
A portion of an ultimate segment (146 mm.), with a telson 
(fragment 30 mm.) and one stylet (not quite perfect, 22 mm.). The 
segment retains scarcely any of the test, but shows traces of an 
ornament of irregular small tubercles and interrupted longitudinal 
lines; and the distal margin of the segment has a coarse comb-like 
fringe, consisting of a regular set of thin elongate tubercles, remind- 
ing one of the drop-like tubercles on marginal parts of some 
Eurypterids. 
The head of the telson is wrinkled longitudinally, and both the 
style and the stylet are ridged and furrowed. This form being new 
to us, its comb-like fringe suggested the name pectinata. 
In earthy micaceous blue-grey limestone, from the Ringsjén, 
Scania. 
This specimen is “fig. 2” in Angelin’s unpublished “Tab. B.”
