The Museum has received from Mr. Eapier several most 

 interesting Corals — among others, the two following Gorgo- 

 noids with calcareous axis : — 



Eayxeeella. 



Coral much branched, fan-shaped, expanded in a plane ; 

 branches and branchlets pinnate ; branches diverging, sub- 

 cylindi-ical, slender, nearly of a uniform size ; branchlets op- 

 posite or alternate, diverging. Bark thin, with an even, very 

 slightly coiTugated surface, internally finely granular. Polype- 

 cells prominent, roundish, close together, diverging in-egularly 

 on all sides of the slender branches ; apex rather conical, con- 

 tracted, with a central dot. Axis calcareous, hard, white, with 

 well-marked longitudinal grooves. 



Baynerella aurantia. 



Coral orange-yellow ; branches and branchlets diverging, 

 pinnate ; branchlets ending in a broader tubercle, simple, 

 rarely forked.

Beaxdella. 



Coral very much branched, very slender, linear ; branches 

 diverging, pinnate, and nearly parallel to each other ; branch- 

 lets pinnate, opposite or alternate, diverging at nearly right an- 

 gles, often sinuous, inosculating, uniting the diverging parallel 

 branches into an irregular network. Bark, when dry, veiy
