Cretaceous Species of Podoseris, Dune. 27 
This species is closely allied to P. elongata, Dunc., but 
the arrangement of the septa forms a satisfactory distinction, 
the long series preponderating, and they are wide apart. 
Podoseris anomala, sp. nov. (Pl. V. figs. 3 and 4.) 
Corallum simple, moderate in size, constricted above the 
wide circular attached base; ending superiorly in a_pro- 
jecting ridge some distance below the true margin of the 
calice. Calice tall, small, open, slightly deformed, with an 
indefinite margin. Septa numerous, unequal, irregular in 
direction inwards, long, straight, or curved, moderately stout 
and distinct, some reaching the axis and uniting there, 
others passing far in and uniting with those which pass 
to the columella, or not. Many rudimentary septa barely 
passing inwards; septa of the fifth cycle often absent in 
some systems, the free edge of the septa with large granules 
which slope over the flanks. Coste of two kinds—those 
reaching the calicular margin and uncovered by epitheca, 
and which are subequal, granular, or alternately large and 
small, wavy or straight, uniting and bifurcating ; and secondly 
those below the upper ridge and which reach to the base of 
the coral and are covered with epitheca; they are large, 
straight, swollen at intervals and joined by synapticule, and 
there are many small coste in the spaces between the larger. 
Epitheca granular, upon the lower part of the stem. 
Height 15°5 millim., breadth of base 13 millim., of calice 
7 millim. 
Podoseris Jessont, sp. nov. (Pl. V. figs. 5 and 6.) 
The corallum has a small circular base, is high, subcylin- 
drical nearly to the calicular margin, but before that is 
reached there is a definite enlargement, so that the upper 
part is broader than the rest. Calice broad, widely open, 
slightly concave ; the margin is higher than the axial region, 
the septa slope to this, which has a fossula with the ends of 
the larger septa rising in the midst, with a rudimentary colu- 
mella formed by their ends with some slight additional struc- 
ture. Septa small, crowded, unequal in width and length, 
usually alternately large and small, some straight, others 
Wavy, some uniting with others, upper edge slightly con- 
vex, the inner or axial part of some seventeen to twenty 
septa rising up and surrounded by a groove in a small sunken 
fossula. The septa usually diminish in thickness from the 
margin of the calice inwards, and some are stout, and many
