Four flattened pieces (Figs. 3-6) of tapering, riband-like telsons, 
with a central line, sometimes raised, but usually sunken, which was 
originally a ridge in all probability. From it, on each side, numerous 
parallel, oblique, sigmoid lines pass downwards and outwards, and 
these end at the edges with sharp upward curves, defining the small 
sub-triangular teeth of a serrated fringe. This is of varying strength, 
and is sometimes backed by a slight ridge. Except in the serrated 
edges these specimens correspond in essential particulars with the 
dorsal aspect of the triangular or bayonet-like lower portion of the 
telsons referred by Barrande to Eurypterus, but by O. Novak, lately 
and with precision, to his new genus Phasganocaris. 
These fragments, dark brown and chitinous in appearance, are in 
an earthy yellowish-grey limestone (Lower Ludlow) from Vatten- 
fallet (the Waterfall) near Wisby, Gothland. 
Fig. 7 shows a longer and narrower piece of a telson, badly pre- 
served, much crushed and wrinkled, but retaining some convexity, 
and its upper end showing a slightly triangular section. It is dark- 
brown and chitinous, in a blue-grey, calcareous, and finely micaceous 
shale (of the Ludlow series), from the Ringsjén, Scania.

Supplemental Note on Ceratrocaris ANGELINI. Pl. V. Fig. 1. 
Prof. Lindstrém has favoured us with a careful sketch of the 
ridges and pits seen on the original specimen of Ceratiocaris Angelini, 
J. & W., but very obscure on the plaster cast. He writes (Mar. 2) : 
“The tip of the telson in Cer. Angelini is only slightly longer than
