NO- 1473. S(mE NEW FUNGIM-VAUGHAN. 829 



RECENT SPECIES. 



Group of F. REPANDA Dana. 



FUNGIA SAMBOANGENSIS, new species. 



Plate LXVIII and Plate LXIX, fig. 1; Plate LXXIV, fig. 1. 



Coralluni rather large, circular in outline, slig-htl}- arched, base gently 

 concave. Wall perforate, numerous slits between the costre to 

 near the center, around which is an imperforate area about 25 nnn. in 

 diameter. CostiB rather fine, not greatl_y ditferentiated in size. Ever}'- 

 fourth or sixth may be somewhat thicker and more prominent than 

 those intervening-. All the costm are s2nno.<<e, the spines smaller near 

 the edge, where they are of only moderate size, or rather small, and in 

 a single series. Toward the center they become larger and the distri- 

 bution is not quite so regular as near the periphery. On the central 

 imperforate area the spines are again somewhat smaller and are dis- 

 tributed irregularly. The shanks of the spines are smooth or with 

 only occasional granulations; the tips are rounded, blunt, often though 

 not always swollen, and are graivulatnl. 



Septa vneqiial^ even on the periphery, where usually' there are at 

 least three different heights and three different thicknesses; all septa, 

 even the thicker, are thin, the smallest ver}" thin. On the upper sur- 

 face they are verj' unequal, of three or four difl'erent heights. About 

 eighteen septa reach the axial fossa. The inner edge of these are 

 prominent and fall steeply to the bottom of the fossa. Between each 

 pair of these longest septa are from one to three shorter ones of prac- 

 -tically equal height. Then there are several lower, thinner septa, 

 scarcely half the height of the taller, between each pair of taller ones. 

 Septal margins serratel}" dentate. On the larger septa the serrations 

 are coarser— in fact, decidedly coarse— near the periphery; become 

 smaller and ultimately obsolete toward the fossa. Near the periphery 

 there are tive or six dentations to the centimeter; nearer the fossa, seven 

 or eight. There are no tentacular lohes. The septal faces show low, 

 broad ridges corresponding to the serrations; the whole of the septal 

 are covered with minute granulations; near the edges are minute wavy 

 lines running parallel to the margins. The synapticula are distinctly 

 visible from above. 



Columella distinctly developed, composed of very delicate, spong} 



tissue.
