1 liav(< pliinod doubtfully under the genus Thracia the largest of 

 the ti\w\\ riMuuins found in the Singapore deposits. Unforlunatoly 

 tho un»l)o is wanting, and its exact position is very uncertain, 

 although it was possibly more or less mesial. The specimen consists 

 of a considtMubly fnuMured natural cast representation of the left 

 valve of an elongate shell, rounded anteriorly, with a pri)bably nearly 

 horizontal dorsal margin, and ])ossibly an elli|)tically curved base. 

 It has the apjiearance of having had originally an oval outline, and 

 in the posterior region, where the principal characters are merged, there 

 is an obtusely angulated area descending obliquel}' from the umbonal 

 region to the median angulation of the truncated margin, producing 

 a cuneiformity of outline which is repeated within by the oonoeutrio 

 growth-lines.

The largest of the two speoinu^ns appearing to bear a relationship 

 to PodozumitcK laitceolntuK consists of a long leaf-like body embediled 

 in the day-matrix, much crushed and bent about at its widest end, 

 and din\inishing rather rapidly at its other extremity for jirobable 

 attachment to a rachis, whilst a series of i>arallel lines or venations 

 traverses the entire surface of the organism. There is no indicjition 

 of a stem, although the peculiar narrowing of the supposed basal end 

 would suggest that that part would form the pi)int of attachment. 

 The broader end is not complete, so that the original length is 

 uncertain, but the maximum width of the pinna can be given as 

 IG nun. Although much broader than the pinnie of typical examples, 

 this s])ecimen is by no means the widest known. Dr. Yabe having 

 recently figured son»e specimens froui Korea with a measurement 

 of 20 mm. 



The second specimen represents another fragmentary pinna, which 

 is of smaller dimensions, being i>nly 7 mm. wide. It is, however, of 

 interest, since a well-rounded, slightly notched, basal margin can be 

 seen, as well as the characteristic parallel venations, the more 

 lateral of which curve slightly inwards at the termination. Un- 

 fortunately the apical region is incomplete, and there is no means of
