II.—On some Palæozoic Phyllopoda
Published online by Cambridge University Press: 01 May 2009
Extract
In the Museum of Practical Geology there is a specimen of Ceratiocaris (No. 4435), from the vicinity of Ludlow, which was not noticed by us in the “Monograph of British Palæozoic Phyllocarida” (Palæontographical Society), 1888. It is a squeezed carapace, evidently allied to the Ceratiocaris cassioides there described and figured, pages 59–61, pl. iii, fig. 9; pl. iv, fig. 7; and pl. vii, figs. 4–6. The specimen appears to have been bivalved. The contained animal matter has caused an irregular convexity (as seen also in figs. 4–6, pl. vii above mentioned), especially in the anterior third; and here it has been broken down, leaving a small rough cavity in some obscure organic material.
