ANACROrOKA.f 



Maclreporida) of ramose habit. Axis and apex of branches formed by 

 a spongy ccenenchyma. New calicles formed centripetally, i.e. from the 

 base towards the apex; no calicle of any kind at the apex. Calicles 

 equally distributed all round stem and branches, with a tendency to an 

 arrangement in longitudinal series. Septal system well developed, com- 

 prising two cycles of six septa each, two (approximately upper and lower) 

 primaries being larger than the fonr lateral primaries. 



Obs. — Anacropora is based on the new species A, forbesi, described 

 below, and on some forms which occur in the Challenger coricction of 

 reef-corals, to be hereafter described by Mr. J. J. Quelch, of the Natural- 

 History Museum; I have had the advantage of Prof. Duncan's and Mr, 

 Quelch's opinions on this important form, opinions which have been freely 

 and kindly given. The general growth and other characters given above 

 are essentially the same in all the species. In all the growth is low, the 

 branches tending to form inosculations between each other ; the stem and 

 branches are cylindrical, and no distinct tubular calicles are formed. 



From Madrepora this genus differs markedly in the centripetal 

 production of the calicles, by which the youngest calicles are always the 

 uppermost. From the snbf enns Isopora, Studtr (see he, inf. cit.), it differs 

 in the same point, as well as in its slender dendroid growth; but the first 

 distinction is not so marked at first sight, since the peculiar growth of 

 Isopora almost necessitates tiie absence of a distinct apical calicle, but (as
