Thi cription of the specimens of the Sibo ection: 



ndroid. Gemmation t . i k i 1 1 l; place near the calicular margin, sometimes two 



or tl being formed ai the same time, sometimes onl) one. The rMr.illit.-s are 



I in rows along the stem and branches, but are irregularly distributed facing in all 



often two coralliti - are formed at the same height, one opposite the other. The 



: of tin- bigg ) Stal o cm.. I lx- corallites are five mm. long at most, 



m. iv or may nol in rease in diameter from the base toward the calicular margin, the 



a :is "f the elliptical calicle being 3.5 to 5 mm., and the short axis 3 to 1 mm.. The 



te, visible over the whole length of the stem. are low, flattened above, equal, not perforate, 



covered with fine irregularly scattered granulations. I1ucrr0si.il furrows very narrow, with smal! 



perforations. 



rhe septa are arranged in three cycles, those of the fourth cycle being developed in a 



systems, as is shown in the diagram (fig. 4). In the top-calicles there are always 

 four complete cycles. The sepia of the first cycle project very little above 

 the calicular margin; they slope down in the calicle and bend rather suddenly 

 or slowly in a vertical direction. The septa of the higher cycles do not pr< 

 a- far in the calicular fossa as those of the first cycle. All the septa are thin, 

 have an entire edge or smal! teeth and only a few granulations on the sides 

 The depth of the calicle is from one to two mm., in the axial calicles it may be more 

 The columella is one mm. long at most, composed of a few, thin, twisted, band-like trabeculae, 

 projecting from the bottom of the calicle. 



This species seems to be nearly allied to the Dendrophyllia gracilis M.-Edwards and Haime. 

 The smal! specimen described by Bourne seems to have been a young one. The diameter 

 oi the calicle is two mm. according to Bourne, otherwise mv specimens agree in all resj 

 with his description and figure.

I >i Blainville mentions both his species, adding that they are- the Oculina anastomosans 



laan and Oculina de liaan from the collection of the Leiden Museum. There 



not exist a description by de Haan. Milne-Edwards and II umi give a*good description 



right in uniting both species. The real D. cribrosa^ according to the old lab 



ises also, though not to the same extent. The biggesl specimen from Japan) is 20 cm.
