sides of the trunk, divide and subdivide rapidly into other smaller branches 

 and branchlets, producing a densely ramulous frond. The branches ascend 

 ami diverge usually at an angle of about 50 ; the branchlets often spread 

 at ri'dii angles, and do not coalesce. Papilla? numerous, crowded on the 

 branchlets, elongated, conical. Color grayish yellow; axis white; inter- 

 nodes yellowish brown. — Sooloo Sea; J. D. Dana, U. S. Expl. Exp. 



Melitodes oehracea Verrill. 



Syx. his oehracea Linx. ; MelUcea oehracea Lamx. 1812. — Singapore, 

 Capt. W. II. A. Putnam. 



The name Melitaia having been used for a genus of Insects by Fabricius 

 in 1808, lour years before it was employed by Lamouroux, we have adopted 

 Melitodes for this genus, as restricted by Gray. (See Proc. Zobl. Soc. 

 Lond. 1859, p. 185.) 



Melitodes virgata Verrill. 



Syx. Melitaia oehracea (pars) Dana (from Feejee Islands). 



A comparison of the specimens collected by the U. S. Exploring Expe- 

 dition at the Feejee Islands with several hundred specimens of all forms 

 and sizes from Singapore, in the collection of the Museum, proves that 

 they are unquestionably distinct, though closely resembling one another in 

 general appearance. 



The principal branches in M. virgala rise nearly parallel, and are much 

 more elongated, tapering and subdividing far less rapidly than in M. ochra- 

 cea. The calcareous segments are also longer, and the general appearance 

 of the coral is more open. — Feejee Islands; J. D. Dana, U. S. Expl. Exp.

 Town; J. 1). Dana, U. S. Expl. Exp. 



I am unable to find any generic differences between this species, which is 

 the type of Mopsella Gray, and those subsequently referred by him to 

 Melitella, and have, therefore, united the two genera.
