Cretaceous Sjjeci'es o/Podoseris, Dune. 27 



This species is closely allied to P. elongata, Dune, but 

 the arrangement of the septa forms a satisfactory distinction, 

 the long series preponderating, and they arc wide apart. 



Podoseris anomala, sp. nov. (PI. 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. Costaj 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 synapticulaj, and 

 there are many small costas in the spaces between the larger. 

 Epitheca granular, upon the lower part of the stem.

Podoseris Jessont, sp. nov. (PI. 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 higlier 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
