1909. J MARINE FAUNA FROM MERGUI ARCHIPELAGO. 905 



projects upwards as a long narrow riclge. Other septal characters 

 are identical with those of B. 'parallela. 



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

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



Balanophyllia imperialis Kent [19]. (Plate LXXXYI. 

 figs. 5 a, 6, & c.) 



Two examples, one attached, the other broken ofi' from its 

 attachment. Oorallum straight, conical, one specimen increasing 

 in width much more than the other. Transverse outline of calice 

 elliptical, ends of long axis depressed. 



Table of measurements in mm. 



An " epitheca " covers the lower half of the broader specimen 

 and thi'ee-quarters of the narrower one ; both were covei'ed by 

 encrusting Polyzoa and Serpida tubes. Costse exactly corre- 

 sponding to and continuous with all septa ; in some cases the 

 junction of the fifth to the fourth cycle of septa is marked ex- 

 ternally by a corresponding junction of the costse. All costaj 

 slightly, but very distinctly, and equally exsert, the upper edges 

 where they pass into the septa rounded and entire ; granulations 

 coarse, having the appearance of longitudinal rows of small spines. 

 Septa in five absolutely complete cycles, all covered irregularly 

 with numerous fine granulations ; septa of the first two cycles 

 equal in size, reaching the columella, at which point they are 

 thickened ; edges of these septa, also the upper half of the septa 

 of the third cycle, entire ; septa of the third cycle also reach the 

 columella, and are thickened at the point of junction, lower 

 edges denticulate ; septa of the fourth and fifth cycles grouped in 

 typical Balanophyllid manner round septa of the third cycle ; 

 edges denticulate. Calicular fossa large and moderately deep. 

 Columella well developed, trabecular and spongy, with a convex 

 surface. 



Localities. — Station XYIII. Paye Island. Bottom: sand, shell, 

 and rock. Depth : 10-21 fathoms. The larger specimen. 



Station XXII. Hastings Harbour. Bottom : rock and sand. 

 Depth : 3-20 fathoms. The smaller specimen. 



I refer this very beautifvil coral to the species from Singapore 

 in the National Collection described by Saville Kent [19], in spite 

 of the following diff'erences : the great difierence in size, the 

 larger of the specimens in the present collection is only half the 

 size of the one from Singapore ; the erect mode of growth ; the 

 presence of an epitheca ; the rougher, more spinose character of 

 the costce. However, none of these difficulties need be insupei-able.
