tubulis parvulis vermiformibus jlexuosis, et aliis grandioribus subpar- 

 attelis non lamelliferis (!) perforate. 



Massive. Coralla consisting of concentric or nearly flat beds, perfo- 

 rated by small vermiform flexuous tubules, and others larger, nearly 

 parallel, and non-larnelliferous (?). 



This genus was made by Phillips for the Coscinopora placenta, as 

 figured by Lonsdale, which this author describes as consisting of thin 

 beds, perforated by vermiform cavities bounded each by a white circle. 

 The name is from x aijm s, loose, alluding to its texture.

GENUS DISTICHOPORA. 



Ramosce, pumilcs, flabellatce. Coralla robusta, ramis scepe paulo com- 

 pressis sulco cellulifero disticho. 



Ramose, quite small ; branched in a plane. Coralla firm ; branches 

 often a little compressed, and with a cellular furrow on two opposite 

 sides extending over the extremity. 



These delicate species grow to a height of only an inch or two. The 

 furrow along the edges of the branches, contains a medial series of 

 cellules, somewhat irregular, and another cellular line either side, as 

 is shown in figure 3 a, plate 60. Nothing is known with regard to 

 the animals. 



The species were separated from the MilleporaB by Lamarck. 



1. DISTICHOPORA VIOLACEA. (Lamarck.) 



D. violacea, apice lutescens ; 2-2 " alta ; pdrce ramosa ; ramis paulo 

 compressis, dichotomis, 1-1 "' latis. 



Violet, with the tips a little yellowish ; 2 to 2^ inches high, and ramose; 

 branches somewhat compressed, dichotomous, 1 to 1 lines broad.
