540 Trof. T. R. Jones ^ S. Woodward — Palmozoic Phyllopoda. 



The contained animal matter has caused an irregular convexity (as 

 seen also in figs. 4-6, pi. 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. 



The exposed (right) valve has been damaged by pressure ; but, 

 though much excoriated, it retains on the lower part of the front 

 moiety an ornament of numerous raised flexuous striae (like those 

 seen in fig. 9, pi. iii), trending upwards and forwards to converge 

 at the anterior extremity. Near the postero-dorsal angle, moreover, 

 thei'e is a patch of peculiar reticulate sculpture, with lozenge-shaped 

 meshes. Further trace of this ornament is visible for a little way 

 towards the middle of the valve. In its proportions this specimen 

 comes nearest to fig. 9 in pi. iii of the Monograph, but differs from 

 it considerably ; and still more from the other known examples.

Upper Ludlow formation. 



It has not nearly so great a height in its anterior moiety as 

 G. cassioides ; in consequence of its having a much less convex 

 antero- ventral border. The sinuous strise are comparable with those 

 on both the front and hinder portions of fig. 9 in pi. iii ; but none 

 of the known examples exhibit the neat delicate i-eticulation, with 

 lozenge-shaped meshes, which this additional example shows on 

 its postero-dorsal area. Unfortunately only a limited patch remains, 

 but the ornament is obscurely continued for a little way forwards 

 towards the middle of the valve. 



This peculiar ornamentation sufSces to distinguish the species 

 under consideration, even if the larger size and the more elongate 

 or attenuate outline do not constitute a sufficient distinction.

Several specimens, in a soft grey argillaceous limestone, homo- 

 taxial with the Wenlock Beds, from Lau, near the south-east 

 coast of Gothland, Sweden, have been communicated by Professor 

 Gustav Lindstrom, F.M.G.S. On one piece of this marly rock there 

 are indications of at least six carapaces, flattened, and more or less 

 jnutilated by pressure, some showing a trace of the underlying
