Ill my opinion Dana's Mfundrina rtistica from Wake Island is the same as 

 M. lanirUina I'liicnberj;. Khm/inner has elahoi atcly descrihed the variation of 

 this species. 'I'here are in the LJ. S. National Museum j^ood suites of specimens from 

 DJihoini (1M( nch Somaliiand), received throuf^h Dr. Charles Gravier, and from the 

 soul Ik in IMiilippiius, J. H. Steele, collecior. TheMuriay Island specimen is some- 

 what denser ihaii those from I he oihcr localities, and the collines average lower. 



Dislribulion. Red Sea; Indian Ocean; Murray Island, Australia; southern 

 rhilippine Islands; Samoa; Wake Island. An excellent specimen collected by 

 Ml. Carl I'llschnei at I'aiining Island is in the U.S. National Museum. The species 

 therefore extends fiom ilic cast coast of Africa to l'"annin>i; Islaml.

The following;, is a desci ipl ion of a si)ecimen of 1 his species from Murray Island : 



C'orallum vviih ilailish upper surface, apparcnily lucrusrlnn. 



C'oiallives polynonai. Walls of adjacenl coraliites applied one to the other, fused, or 

 mole or less imperlecl. Ihickness from about 0.5 to nearly 1 mm. finds of septa in the 

 walls ollcn hollow, probably a pathologic character.
