128 PAPERS FROM THE DEPARTMENT OF MARINE BIOLOGY. 



the fossa Depth of fossa, about 12 mm. Septal margins nearly equal in height, the long 

 septa slightly the more prominent. Large septa with from 5 to 7 serrate dentations to I cm. ; 

 small septa with up to 10 similar dentations. . 



Base abundantly perforate, costa? distinct only near the edge. Spines styhiorm, sides 

 smooth, protruding trabecular on the tips; smallest near the margins; tallest in a zone out- 

 side the detachment scar, where a number are compound. Maximum length, 5 mm.; 

 diameter of bases of large spines, 1 mm. 



This is the Fungia confertifolia of Dana, which Doderlein recognizes as one of 

 the varieties of F. fungites. 



There is a second specimen of Fungia, 50 mm. long by 41.5 mm. wide, which 

 had just been detached from the anthocormus. It is immature, but as it has some 

 slits in the wall, a few small costal spines with smooth sides, serrately dentate septa, 

 and tentacular lobes, it probably belongs to F. fungites. 



Station at Murray Island.— Southeast reef, line I, 1,000 feet from shore; water 



17 inches deep. . 



Two large specimens and a recently detached anthoblast were obtained by 

 Dr. Wood Jones in Cocos-Keeling Islands. Greater diameter of the largest speci- 

 mens, 186.5 mm.; lesser diameter, 160 mm. Greater diameter of the second large 

 specimen, 154 mm.; lesser diameter, 149 mm. 



Habitat and color, Cocos-Kecling Islands.- -Dr. Wood Jones made the follow- 

 ing notes: 



"Not at all common, found unattached in barrier and lagoon pools, usually 2 or 3 

 together It would be uncommon to find half a dozen in an afternoon's walk over the inner 

 edge of the barrier at low tide. While living the color is pinkish brown, in some places 

 having a greenish tinge. The largest specimen was kept alive for a long time and became 

 more pigmented as its vitality lessened." 



Distribution.— From Red Sea and the east coast of Africa eastward to Tahiti 



and Samoa.

Two specimens from Cocos-Keeling, both with greatly developed tentacular 

 lobes, but one is strongly arched, while the other is flat. Specimen No. 1 is 147 mm. 

 in greater diameter, 104 mm. in lesser diameter, and 76.5 mm. in height. Speci- 

 men No. 2 is 129 mm. in greater diameter, 90 mm. in lesser diameter, and 35 mm. 

 in height. The septal dentations of No. 2 are a little larger than those of No.i, 

 and in places are ragged, the condition apparently being due to injury. No. I is 

 var. dentigcra Leuckart, while No. 2 is var. placunaria Klunzinger, following the 

 treatment of Doderlein. 



Habitat and color, Cocos-Keeling Islands.— -Dr. Wood Jones states: 



"Not at all a common form, occurs mostly in pools on the inner edge of barrier flats. 

 It is not found more than once or twice in a mile of barrier; but where one is found others 

 are almost certain to be near. While alive the color is a delicate pink, becomes more pig- 

 mented under adverse circumstances." 



This species is found in holes 5 to 1 5 feet deep, on the reefs off Pukoo, Molokai, 

 Hawaiian Islands. 1 



Distribution— Red Sea; east coast of Africa; Indian Ocean; tropical Pacinc to 

 Fanning and Hawaiian Islands. Mr. Carl Elschner collected the species in Fanning 



Island. ^
