Fungus marinus lapideus foliolis erectis, serratis, &c., Seba, iii. tab. 109, fig. 4. An 

 upper view of a calicle similar in its lobes to the above. The gyri are three-eighths to 

 one inch broad, and the whole measures six inches by three in breadth ; including all its 

 sinuosities, the cell is about twelve inches long. 



10. MUSSA CEREBRIFORMIS. (Dana.') 



M. maxima, hemispherica, discis linearibus, sinuosis, kmgissimis. Coralr 

 lum meandrinum, cellis j|" latis, et kmgissimis, lobis scepe rectis et 1' 

 longis, ad cellce fundum 1-2 lamellis; lamettis tenuioribus, vix rotun- 

 datis, dentatis. 



Very large, hemispherical ; disks very long, linear, and sinuous. 

 Corallum meandering ; cells | of an inch broad and very long, the 

 lobes often straight and a foot long ; at bottom of cell one or two 

 longitudinal lamellae ; lamellae rather thin, scarcely rounded above, 

 dentate.

This noble species grows in regular hemispheres several feet in 

 diameter, consisting of very large sinuous meandering plates. It 

 resembles the last, and might be an older specimen of the same ; but 

 the lamelte are thinner, and, instead of three or four, there are only 

 one or two longitudinal lamellae connecting the polyp-centres at the 

 bottom of the cell. The texture of this species, moreover, is more 

 open, and its exterior less decidedly striate than in the multilobata ; 

 nine to twelve lamellae meet at each polyp-centre, but they are 

 scarcely convoluted at their junction. 



11. MUSSA REGALIS. (Dana.) 



M. subhemispherica, polypis grandibus, scepe lateraliter coalitis, discis 

 elongatis, sinuosis. Corallum meandrinum, caliculis 1-1 J" latis, in- 

 terdum " sejunctis sed scepe coalescentibus. extus striatis, non echina- 

 tis; cellis profundis (scepe 1") interdum 6" elongatis; lamellis ince- 

 qualibus, dentatis, fere %" exsertis.
