40 LEPIDOPOUA. 



LEPIDOPORA PouRT. 



Corallum liiioly biiuicliiiiu' ; interscptal cliainhcrs separate from eali- 

 cles, in the shape of slit tubercles; lip of caliele projecting as Ji scale 

 over the caliele. 



This g-enus combines the characters of Errina and Crvptohelia, 

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

 bers of the former. 



Lepidopora glabra Podrt. 



Errina glahra PoURT. Bull. ^Iiis. C'omp. Zool., No. C. 



Plate VII., figs. 8 and 9. 



Coralhnn tlabellate, not coalescing; the older parts of the stem 

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

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

 cii'cular; when terminal, surronnded ))y a few interseptal pores, which 

 become separated from the calicles in the subsequent growth and tbrni 

 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 i'ossa. AmpulhiJ 

 scarce and small, suiootli. Color white. Height 5 to 7 cm., diameter of 

 branchlets .7 to 1 mm., of main branches about o unu.

Plate III., fig.s. 17, IS, and 19. 



Corallum branching, flal:)ellate, very slender, finely granulated and 

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

 ceding species, but distinctly bila1)iate when terminal, and covered by a 

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

 than in L. r/labra* 



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

 Lepidopora, sent from Fayal by Miss Dabney. From waiii- of specinien-i of couip oison, and rflyini;
