316 ZOOPHYTES. 



Pdyphyttia pelvis, Quoy and Gaymard, Voy. de 1'Ast. iv., 185, pi. 20, figs. 8-10. 

 The specimen figured was from Port Carteret. Figure 8, which appears to be of the 

 natural size, represents a small shallow basin, inverted, three inches long and three-quar- 

 ters of an inch deep. 



NOTE. Quoy and Gaymard refer here, and with apparent reason, the Litliactinia 

 novce-hibernice of Lesson (Illust. de Zool. PI. 6). It is described by Lesson as occurring 

 in broad disks, measuring about five inches by four and three quarters, a little concave 

 on one side. The corallum is thin, with the lamella: about a fourth of an inch long and 

 denticulate. Below, the margin, for nearly half an inch, appears, from the figure, to be 

 striate, and beyond this the points are scattered, though arranged in successive zones 

 (zones or wrinkles of growth ?) The tentacles are described as of a bistre colour, irised 

 or rose-coloured above, and bronze below : they are large and inflated, and sometimes ten 

 to twelve lines long. From Lesson's figure A., which represents a mouth surrounded by 

 tentacles, there appear to be some stellate oririmes, like those on the medial line in the 

 talpa. This coral was obtained by Lesson at Port Praslin, New Ireland, upon the coral 

 rocks, in one or two feet water, while in the Coquille, in August, 1823. 



II. Oririmis valde conspicuis, nullis median-is seriatis. 



5. POLYPHYLLIA FUNGIA. (Dana.} 



P. orbicularis, convexa et subtus concava, polypis omnino sparsis. Co- 

 rallum subcrassum (4-6'"), oririmis profundis, 1-1|'" latis ; lamellis 

 non radiatis, valde prominentibus, tenuissimis, incisodenticulatis, 

 3-5'" longiSj margine s&pe, 6-12'" ; subtus radiate conferlimque 

 echinulatis. 



Circular, convex, and below concave; polyps throughout scattered. 

 Corallum rather stout (4 to 6 lines thick) ; oririrnes deep, 1 to 1 

 lines broad ; lamellae not radiate, very prominent and thin, inciso- 

 denticulate, 3 to 5 lines long, and those of the margin 6 to 12 lines; 

 below crowdedly and throughout radiately echinulate. 



The convex circular form of the specimen here described, is quite 

 regular; it is about an inch in height, and half an inch thick at 

 middle, and in .diameter four inches. It belongs to the collections of 

 the Academy of Natural Sciences at Philadelphia. 



In the absence of a medial series of oririmes it resembles the fol- 

 lowing species ; but it is very much stouter, and the oririmes are very 

 distinct.
