The clumps are neat, low-convex, and much branched. The 

 branches are crowded to within one-third to half an inch of one an- 

 other, and are mostly a fourth of an inch or less in thickness. The 

 cell is large and shallow, and has a flat bottom ; those low on the stem 

 are rather distant, and a delicate line may be traced around them as 

 in some Seriatoporse. The species most resembles the damicornis, of 

 which I had considered it a dwarf variety ; but it is a much neater 

 and more slender species, and has larger cells. 



3. POCILLOPORA BREVICORNIS. (Lamarck.) 



P. humilis, late cespitosa, conveza, breviter ramosa, ramis creberrimis, 

 vix 2'" sejunctis, 4-6"' crassis, apice scepe compressiusculis aut lobatit. 

 valde obtusis et verrucosis, verrucis 1-1^'" longis, interdum acervatis. 

 Corallum cellis J-|'" latis, columettd nulla. 



Low and broad cespitose, convex, ramose, branches very short and 

 much crowded, scarcely 2 lines apart, 4 to 6 lines thick, often some- 

 what compressed above or lobed at apex, very obtuse and verrucose, 

 with the verrucas 1 to 1J lines long, and sometimes acervate. Co- 

 rallum having the cells J to a line broad, and without acolumella.

The low clumps are three inches to three and a half high, and five 

 or six broad, and consist of short crowded stems with broad summits, 

 rough with short verrucse. The branches are sometimes an inch 

 wide at top. The intervals between the branches are small and quite 

 regular. The separated stems resemble a fragment from the dami- 

 cornis, but in mode of growth and size, the species are wholly different.
