TUEBINOLTAD^. 
Size. 
Diameter of long axis, -SI inch ; of short axis, '24 ; height ‘21 to -14, 
unequal because the corallum is built partly on a shell and partly on a 
Sevpula tube adhering to it. 
Animal. Unknown. 
Locality. 
The Moray Fh'th ; deep water. 
It is with some doubt that I re er this and the two 
following species to the genus Faracyatlius. Generally 
agreeing with its characters, they all have the peculiarity 
of the union of the palules into a horizontal perforate 
platform, which does not appear to be the case with any of 
the hitherto described species. 
The single specimen on which the above description is 
founded was forwarded to me by my kind friend, Mr. 
Gregor, of Macduff, Avho obtained it from deep water. 
It is affixed to the inside of an old valve of Cyprina 
Islanclica, and has the appearance of being recent. 
The only species of Paracyathiis with which this is likely 
to be confounded is the fossil P. crassus of the London Clay ; 
but from this it may be distinguished by the union of the 
palules, by the ribs being proportionally thinner and more 
remote, and by the diversity of their upper and lower 
portions. 
Paracyatlius is derived from irapa, near, and KvaOo^, a 
cup (the element of Cyathina). I have assigned a specific 
name from Taxilium, the ancient appellation of the pro- 
montory now called Kinnaird’s Head, off which the specimen 
was taken.
