12 to 20, often uilli other ni'liimritarv ones, rather thick ami strong, with sharp, spiny granulations 

 or teeth on the sides and edges, and mostly eonflnont witli tliosc of adjacent cells. Color of the 

 unbleached coral ash gray or yellowish gray. 



Height of coral 3 inches; length of living portion of branches 0.2.5 to 0.4.5; the diameter of the 

 larger cells 0.1 of an inch.

Quelch ill his ChalliMi<ror Reports gives tlie Iliiwuiiiin Islands, reefs at Honolulu, 

 and the Fiji Ishmds as additional localities. 



The United States National Museum pos.sesses 3 .specimens from Panama, pre- 

 sented by Professor Verrill. These specimens are all small, smaller than the largest 

 specimen describ.'d by Professor Verrill. Their measiu'ements are: 



« Base broken. 



Tlic lixing portion of the corallum is maro-ined by a thin, pellicular, easily 

 detachable, concentrically minutely striate and wrinkled epitheca, remnants of which 

 may be seen on the lowei'dtnid portion, but if it were once complete it has now lieen 

 mostlj' broken away. 



The general description of Professor Verrill is as good as can be desired. The 

 septa are almost imi)erfoi'ate, occasionally. t)ut very i-arely, a pore could be dis- 

 covered. Stout synapticula well developed. There are also a few thin dissepiments. 



Dr. W. T. Brigham has sent to the United States National Mu.seum 2 specimens 

 of a Sti-'phanaria, from Pidvoo, Molokai, depth 3 to feet, that I am unal)le to 

 differentiate from S. xtdlata. The specimens from the Hawaiian Islands often, or 

 usually, have -somewhat narrower septo-costa? and the synapticula between them are 

 more numerous and more visible than in the Panama specimen. It seems, howevei-, 

 that no specitic difference can be based on these characters, as the specimens from 

 both localities show variation. 



Professor niniden obtained specimens at W'aikiki. Oahu. 



STEPHANARIA BRIGHAMI, new species. 



Plate XLIII, figs. 4, 4(i, 5. 



Corallum forming a rounded chunp of stubby branches; height, 47 mm.; greater

 form subterete or somewhat compres.sed, diameter below terminal divisions 6 to 8 

 mm. Lower edge of living portion epithecate; living portion measures 10 to 13 mm. 

 in length. Terminal branchlets or Iol)es of very une(|ual size, varying from indis- 

 tinct lobations to 7 nun. in length.
