On the structure and affinities of the genus Monticulipora and its sub-genera, with critical descriptions of illustrative species . s simply filled with light-coloured sclerenchyma, which usuallyexhibits fine concentric laminse of deposition in the immediateneighbourhood of the actual tube-cavity, but seems to be abso-lutely structureless just at that central point where we should 40 THE GENUS MONTICULIPORA. expect to find traces of the original boundaries between thecoralHtes. This state of parts occurs in forms like M. tumida^Phill., M, Andrezvsii, Nich. (fig. 2, d), M. gracilis, James, , Nich., and various other allied types. Some forms of Monticuliporoids show peculiarities in thestructure of the wall slightly different to any of those alludedto above, but the preceding are the most important types withwhich we have to deal; and our knowledge on this subject, asderived from tangential sections, may be corroborated, and insome points supplemented, by an examination of longitudinalsections. In these we see the same great apparent differencesthat have been noted in tangential sections. Thus, in some.
