Figs. 18-20, in pi. 3 {Rosalina Poeyi, D'Orb.), represent the 

 typical Cymhalojpora Poeyi (Carpenter's ' Introd. Foram.' 1862, 

 p. 215). R. squamosa^ D'Orb., is the high-coned, livid- 

 coloured, purple-topped Cymhalopora of the West Indies,

 a closed-in polystomellous form of the same, and is common 

 in the tropics, both east and west. In C. huUoides the last 

 septal wall closes in the whole umbilical face, and is multi- 

 perforate, with large passages similar to those on its isomorph 

 Orhidina (formed of Glohigerina in an analogous manner) 

 and in the wild Spirilline forms of Pulvinulina (Phil. Trans, 

 vol. civ. p. 390).
