the septa in the Ellis and Solander plate appear stronger than do 

 those in the Vaughan photograph. The Ellis and Solander plate 32, 

 fig. 1, apparently Madrepora tibicina of their text, is quite possibly 

 identical with Verrill's more recently described species, in which 

 event the earlier name must take precedence.

Pocillopora cespitosa Dana 



•f 



Type : This species vi^as discovered by the United States Ex- 

 ploring Expedition in the Sandwich Islands, and described and 

 figured by Prof. J. D. Dana, whose type is deposited in the United 

 States National Museum. 



Distribution: Hawaiian Islands, littoral zone: Kaunakakai 

 and Pukoo, Molokai Island, reef at Honolulu, reef at Kahana and 

 Waikiki, Oahu (Dana; Vaughan) ; Laysan Island (Studer). 



Material examined: A small specimen, about five inches 

 high, was collected at Honolulu, Oahu, Hawaiian Islands, Decem- 

 ber 14, 1928, by the '*Ara." 



Remarks : The present material agrees in all essentials with 

 the original description and illustrations given by Dana. Three 

 new varieties of Dana's species were established by Dr. T. W. 

 Vaughan (1907), all being based on Hawaiian material.
