40 LEPIDOPORA. 



LEPIDOPORA Poxjbt. 



Corallum finely branching ; interseptal chambers separate from cali- 

 cles, in the shape of slit tubercles; lip of calicle projecting as a scale 

 over the calicle. 



This genus combines the characters of Errina and Cryptohelia, 

 having the raised lip of the latter and the separate interseptal cham- 

 bers of the former. 



Lepidopora glabra Pourt. 

 Errina glabra PomsT. Bull. Mus. Comp. Zobl., No. 6. 



Corallum flabellate, not coalescing ; the older parts of the stem 

 much thickened, faintly striated and granulated; a row of very small 

 perforated tubercles on each side of the branches. Calicles very small, 

 circular; when terminal, surrounded by a few interseptal pores, which 

 become separated from the calicles in the subsequent growth and form 

 the lateral perforated tubercles. The calicles on one face of the 

 branchlets hid by a scale-like projection ; calicles obsolete on larger 

 branches. Columella styliform, hirsute, in a deep fossa. Ampullae 

 scarce an 1 small, smooth. Color white. Height 5 to 7 cm., diameter of 

 branchlets .7 to 1 mm., of main branches about 3 mm. 



Off Havana, in 270 fathoms. 



Lepidopora cochleata Pourt.

Plate III., figs. 17, 18, and 19. 



Corallum branching, flabellate. very slender, finely granulated and 

 striated, studded with echinulate ampulla?. Calicles formed as in pre- 

 ceding species, but distinctly bilabiate when terminal, and covered by a 

 large spoon-shaped lip when lateral. Perforated tubercles more distinct 

 than in L. glabra* 



Height 2 cm., diameter of branchlets .3 to .4 mm. 



Off Havana, in 270 fathoms ; rarer than preceding. 



* The Museum nf Comparative Zoology possesses remarkably fine specimens of a third species of 

 Lepidopora, sent from Fayal by Miss Dabney. From wan^ of specimens of comp nison, and relying 

 on the very brief definition of Errina aspera Gray, they were labelled with that name, and cata-
