I have placed doubtfully under the genua Thract<t the largest of 
the shell remains found in the Singapore deposits. Unfortunately 
the umbo is wan ling, and its exact position is vary nn certain, 
although it was possibly mure or less mesial. The specimen consists 
of a con side rah I y fractured natural east re presented on of the left 
valve of an elongate shell, rounded anteriorly, with a probably nearly 
horizontal dorsal margin, and possibly an elliptieally curved base. 
It has the appearance of having had originally an oval outline, and 
in the posterior region, where the principal characters are merged, there 
is an obtusely ang dated urea deacon ding obliquely from the nmbooal 
region to the median align hit ion of the truncated margin, producing 
a oun«ifbrmity of outline which is repeated within by the concentric 
growth* lines,

The largest of the two specimens appearing to bear a relationship 
to i^doMifnttoi lunceolntna consists of a long leaf-like body embedded 
in the clay-matrix, much crushed and boot about at its widest end, 
and diminishing rather rapidly at its other extremity for probable 
attachment to a molds, whilst a series of parallel lines or venations 
traverses the entire surface of the organism, Thera is no indication 
of astern, although the peculiar narrowing of the supposed basal end 
would suggest that Unit part would form the point 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 
16 mm. Although much broader than the pinnae of typical examples, 
this specimen is by no means the widest known. Dr. Tabs having 
recently figured some Hpeoimunu from Korea with a measurement 
of 20 tn to. 
The second specimen represents another fragmentary pinna, which 
is nf smaller dimensions, being only 7 mm. wide. Jt is, however, of 
interest, since a well-rounded, slightly notched, basal margin can be 
seen, as well as the olmmoLemtio 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
