70 Anniversary Meeting. [Nov. 30, 



is lost on immersion of the coral in nitric acid. The colouring-matter 

 was not analyzed by Mr. Gilliman. 



In the Atlas of the ' Voyage de l'Astrolabe,' Zoophytes, pi. 20. figs. 12, 

 13, 14, the expanded polyps of Heliopora ccerulea are figured by MM. 

 Hombron and Jacquinot. In fig. 14 sixteen very short, simple, conical 

 tentacles are shown, in fig. 13 only fifteen tentacles. The figures are 

 evidently very erroneous. The corresponding description I have been 

 unable to refer to, the volume containing it being wanting in the Hawaiian 

 Government copy. 



In the Zoology of the ' Voyage de l'Uranie,' Quoy and Gaimard, Paris, 

 1824, p. 656, is a description of the polyps of Heliopora (Pocillopora) 

 ccerulea. 



The expanded polyps have radiated tentacles, and are said to entirely 

 hide the corallum when they are in an expanded condition. Experiments 

 proved that communication between the animals is somewhat imperfect 

 since a stimulus applied to any part of the colony caused only the polyps 

 in that immediate neighbourhood to retract themselves. 



In the plates of the ' Voyage de l'Uranie,' pi. 96. figs. 5, 6, 7, Heliopora 

 is figured, showing in fig. 5 the appearance of the coral in the fresh state, 

 but without any representation of the polyps.
