Eupsammince M.-Edw. & H. Hist. Nat. des Coral. 



This group, a subfamily of the Madreporidae, according to Milne- 

 Edwards and Haime, ought to be entirely separated from that associa- 

 tion and constituted as a family by itself, as the same authors had done 

 in their earlier publications in the " Annates des Sciences Naturelles " 

 and in the " British Fossil Corals." It is one of the most natural fam- 

 ilies of the corals, and its affinities are much closer to the Turbinolidae 

 (the polyps being very similar) than to the Madreporidfe, with which 

 it is only allied by its perforated walls.

Corallum elongated, conical, straight, attached in younger stages and 

 often through life ; but frequently also becoming free, by covering up 

 the small object (shell or fragment of shell), after the manner of Hete- 

 ropsammia, or by becoming accidentally detached from it. No epitheca, 

 wall porous, costate to the foot. Calicle rather deep, elliptical. Septa 

 entire, slightly exsert, finely granulated, in six unequal systems of four 

 cycles, with rudiments of the fifth in some of the systems. Columella 

 flat and papillose. Polyp generally brick-red. Height 2 to 3 cm. 

 Diameters of calicle 10 and 15 mm.

logued in the same way in Bull. Mus. Comp. Zobl., No. 3. Having since seen the original specimens 

 of Errina aspera in the British Museum, I have been enabled to recognize the. mistake. The rayal 

 specimens form large flabelliform expansions, of great elegance, resembling Stylastcr Jtabelliformi*. 

 The species is very nearly allied to Lepidohelia glabra, from which it differs by its more crowded 

 branchleta, larger and more numerous tubercles, not confined to the sides of the branches, and 

 rough csnenchyma. I would propose the name Lepidopora Dubneyi for this species, which I cannot 

 find to be described. (See Plate VII., figs. 10 and 11.) The specimens are associated with Caryo- 

 phyllia cyathus, growing from the thicker branches. The spread of the corallum is nearly a foot.
