individuals, becoming more pronounced in older specimens. In 

 all other characters the Burmese specimens agree very exactly 

 with Semper's and Bourne's descriptions of those from the Philip- 

 pines and Geylon. 



Localiti/,— Station IX, Bentinck Island and Court's Island. 

 Bottom: sand and shell. Depth: 12-26 fathoms. 



Balanophyllia stokesiana Milne-Edwards & Haime, 



Lepfopsammia stokesiaiui, M.-Edw. & H. [25]. 



Four individuals undoubtedly belonging to this species. The 

 resemblance in general form and mode of growth is borne out in 

 detail in the characters of the costee and septa. The columella is 

 rather less developed than in the Philippine species, but projects 

 upwards in the calicular fossa. 



Locality. — Station XXII. Hastings Harbour. Bottom : rock 

 and sand. Depth : 3-20 fathoms, and shore. 



Balanophyllia profundicella Gardiner [14]. 



Three specimens which, with much hesitation, I refer to this 

 species, as they do not appear to difter sufficiently from the de- 

 scription of the type-specimen to justify the creation of a new 

 species. 



Table of measurements in nun. 



In all three examples the coralhun is straight and cylindrical, 

 attached by a spreading base. Epitheca absent ; costse correspond 

 to septa, broad, subequal, and are visible from the base upwards. 

 Oalice oval, fossa not very deep, with a well-developed columella 

 which projects upwards slightly, and has a rounded, somewhat 

 dome-like appearance. Septa in six systems of four cycles, with 

 traces of an incomplete fifth cycle. Primaries and secondaries 

 somewhat exsert, but in all three specimens the lip of the calice 

 is more or less broken, and the character is not very obvious. The 

 quaternaries fuse over the tertiaries and again over the secondaries 

 deep down in the calice. The graniilations on the septa of the 

 primary and secondary cycles are extremely fine in the tallest of 

 the three specimens ; in the two others the granules have run 

 together to form fine radial ridges ; the edges are entire ; the 

 edges of the septa of the lower cycles are denticulate. 



In the shallower calicular fossa and the denticulate edges of 

 the septa of the third and lower cycles, these forms resemble 

 B. parvtda (Moseley [28]), which, as Gardiner has pointed out, 

 comes very near to the present species ; but the quaternaries are
