Outside of tlio palar liiiy- cacli septum l)cars from one to tlireo dentations, very 

 irrciiular in size. I was unal)le to distinii-uisii between septal and mural ti-ahecuhe. 

 The interseptal loeuli are extrcnicly narrow: are almost ol>literated by the thick 

 septa. Synaptieula are abundant and ci'owdefl. 



The columella is terminated by a single styiifcirm lubrrcie. risino- al)ove a llat 

 floor across the bottom of tiie palar crDwn: between the pali the tloor is pittetl, 

 giving it a star shape.

'I'lic following description is based on Dana's l\pc specimen, \\liicli is preserved 

 in the United States National Mus(>um: 



Corallum subpyriforiu. attached by the small end, which is slightly expanded on 

 the surface of attachment. Greater diameter, near upper .surface, 43 mm.; lesser, 

 about midway down the specimen. 8n nun.: height, ;is nun. The attachment is some- 

 what ol)lique, as the corallum does not rise perj)endicularly above the base. The 

 upper surface is gradually rounded, without lobations. The l)asal portion is invested 

 by a complete but thin epitheea. extending far up th(> sides of the corallum: ?>?< nun. 

 is the greatest distance across it, measured from the base, and 11 mm. the least. Its 

 surface shows concentric, irregular wrinkles and delicate, tine, concentric striations, 



Calict's polygonal, usually one a.xis longer than the other. The variation in 

 diameter of the more regularly ])olygonal is from 1.2 nun. to 2 nmi. An oblong 

 calice has a greater diameter of 2 nun. and a lesser of \.h. They are smalh-r <>u the 

 summit than on the sides. The sejjta are in two cycles: the primaries may or may 

 not uu'et along the corallite axis; when they do, they can searctdy be said to form a 

 columella, as there is too little fu.sion. The walls are moderat(dy thick or rather 

 thin, of the usual lace-work pattern. 



As there is oidy a single specimen, it does not .seem justifiable to section it in 

 order to describe the sei)tal spines and the mural characters in greater detail. It is 

 hoped that, b\- aid of the de.sci'i])tion and the figures, the species can be identified.
