3. Caryophyllia panda n. sp. 



This species is closely related to C. arcuata Edw. & EL and to 

 Caryophyllia (not Ceratocyathus) zanclwa Seg., also to C. ephyala 

 ruihi, froin all of whick it differs in having the septa of the fourth 

 cycle larger and very much more exsert than those of the third. 



Coralluin curved, moderately compressed, expanding from a 

 stout pedicle which is attached by a broad encrustiug base, the 

 thecal wall is finely granular, the costae showing as fine striee. 



Septa stout, 48 in number in six regular systems, those of the 

 first two cycles are equal and are conspicuously large and exsert, 

 those of the fourth cycle are larger and much more exsert than 

 those of the third: the surfaces of all are denticulate. 



Pali large, flexuous, 12 in number placed opposite the septa 

 of the third cycle ; their surface is strongly but bluntly denticulate. 



The columella consist of two or three curling ribbons. 



The corallum is glisteniug white. 



Greatest height of corallum aboiit 35 millim. 

 Major diameter of calicle 19 »

4. Caryophylla quadragenaria n. sp. 



Allied to C. cylindracea Reuss, C. abyssorum Duncan and C. 

 antillarum Pourtalès. 



Corallum rather elongate, little compressed, gradually and elegantly 

 expanding from a curved, very short, rather slender cylindrical 

 peduncle with an incrusting base. 



The costse, whose granular surface is glazed over by a thin 

 vitreous epitheca, are equal; they are very distinct at the calicular 

 orifice, and thence gradually become less salient until they are 

 lost on the pedicle. 



Septa exsert, 40 in number, arranged with perfect regularity 

 in what appears to be fine systems of four complete cycles; their 

 surfaces are finely denticulate, and their edges inside the calicular 

 fossa are wavy. Those of the first two cycles, which are equal,
