tion at the Canary Islands. Both were dead when obtained, but 

 had preserved their structure, which approaches most closely to 

 the form fibred in the Hasslar Expedition Report. One is 

 round, 22 mm. in diameter across the calicle, while the other is 

 slightly compressed, i/xiS'S mm. 



Localities. — Smaller, 90 fathoms, O'Niel Peak, N.W. \ W., 9} 

 nules, broken shells ; and larger, 30 fathoms, Buffalo River, N., 

 15 miles, coral and mud. 



TO. CARYOPHYLLIA CAPENSIS, n. sp. (PL I., figs. 4 a-d). 



Corallum conical, closely set on the outside with low, equal, 

 finely-granular ridges, corresponding in number to the septa 

 and formed by an epithecal deposit, covering over the costae 

 and to some extent filling in the valleys between to within 2 mm. 

 or less of the edge of the theca 



Calicle rather longer than broad, with theca sHghtly higher 

 against its long axis. Septa five cycles, the last generally in- 

 complete, none more than I mm. exsert, with very little differ- 

 ence between the orders. Primaries and secondaries sub-equal, 

 considerably broader than the rest, tertiaries being intermediate 

 ']:ese three orders alone connected to the columella and with 



itire (not toothed) edges. Quaternaries much thinner, but 



ojecting again in front of the quinaries, and, where the latter 

 are present, generally with from 2 to 4 blunt teeth. 



Pali present in front of the tertiary septa alone, varying from 

 rather thick, round pillars of rough appearance to flattened 

 plates of upwards of rs mm. in iDreadth. Columella rough 

 pillars, varying in size with number present, about 4 mm. below 

 the edge of the theca, almost level with the tops of the pali. 



Locality. — 32 fathoms, lat. 33° 3' S., long. 27° 57' E., sand, 

 shell, and rock.
