 Corals, p. 66. 



A small clump and a large number of fragments were obtained, 

 which correspond closely to Esper's description and to the 

 ' Challenger ' specimen. The lower branches in the clump tend 

 to anastomose freely. The columella varies from a large oval to a 

 round low projection, covered with short blunt spines,

There are three low rounded clumps of this species 5-7 cms. 

 high, and almost flat-topped. A Loyalty Islands specimen differs 

 from the type in having shorter and rounded verrucse. Delicate 

 spinulous striations can be distinguished in most of the calices of 

 the veri'ucse, and represent the septa.

Pocillopora pidchella, Briiggemann, Journ. Mus. Grodeffroy, 

 Bd. iii. p. 203. 



A single branch was obtained, which resembles very closely in 

 all respects the type specimen of this species in the British 

 Museum . 



Eotuma ; outer reef. 



8. PociLLOPOBA LOBiFEEA, Milne-Edwards & Haime. 

 Pocillopora lobifera, Mihie-Edwards & Haime, Corall. iii. p. 304. 

 There are two specimens, which seem to represent the species thus 



named by Milne-Edwards and Haime. Corallum closely resembles 

 that of P. brevicomis in its mode of growth, consisting of much 

 crowded branches little enlarged or divided towards their summits, 

 which are covered over by small narrow verrucae, generally less 

 than 2 mms. high : the verrucse on the sides of the branches 

 lower down are often much longer, but retain almost the same 

 diameter. Q^he calices of the ends of the branches are very small 

 •5-'7 mm. in diameter, angular and relatively very deep ; on the 

 verrucse thev are larger but seldom exceed 'i) mm. in diameter. 

 The coenenchyma between the corallites nowhere exceeds the half 

 of their diameter in breadth ; its surface is covered somewhat 

 sparsely with low spines, which tend to form striations between 

 the calices. Septa and columella can seldom be distinguished.
