Dendrophyllia manni (Verrill) 



Plate 25 



Type : Dr. Verrill's type was collected in the Sandwich Islands 

 by Horace Mann and first described in the Proceedings of the 

 Essex Institute (Massachusetts), in 1866, in his third "Synopsis 

 of the Corals of the North Pacific Exploring Expedition," the 

 majority of which are deposited in the United States National 

 Museum. The first illustration of the type was given by Dr. T. W. 

 Vaughan, in 1907. 



Distribution : This very beautiful small coral is exceedingly 

 rare in collections, being recorded only from the two type clusters, 

 collected at low- water mark in the Sandwich Islands and two speci- 

 mens from Kaneohe, Oahu, Hawaii, collected by Dr. W. T. Brig- 

 ham, deposited in the U. S. National Museum. It is restricted to 

 the littoral zone of Kaneohe Bay, Hawaiian Islands, tide line to 

 one fathom depth. It was not collected by the United States 

 Bureau of Fisheries steamer "Albatross" survey of Hawaiian 

 waters. 



Material examined: Six clusters, taken in one fathom, at 

 low tide, Kaneohe Bay, Oahu, Hawaiian Islands, December 15, 

 1928, by the "Ara." 



Technical description : This corallium encrusts rocks, form- 

 ing clusters, which in the present series tend to sphaeroidal or 

 ovoidal clusters, ranging from one to two inches high and from 

 two to three inches across. 



The corallites have the exterior closely and finely costate and 

 covered with fine, close, granulations. Some corallites are united 

 laterally quite to the top, others are separated distally from one to 

 three or six millimeters ; the average corallite rises six to twelve 

 millimeters above the coenchyma ; the smaller, younger ones being 

 somewhat more numerous than the semi-isolate large corallites in 

 some clusters, while in other clusters the large corallites predomi- 

 nate, these usually being separate laterally for the distal three-
