branches. These in turn bear numerous secondary branches 

 which again divide to form other branches or the terminal twigs 

 which bear the small conical lobes densely packed with rather 

 small, club-shaped polyps, averaging 1.3 mm. in length by 0.8 

 mm. in diameter. There are no scattered polyps on the stem or 

 branches. The spiculation agrees with that of C. philippinensis 

 forma typica, except that there are an unusually large number 

 of the small, smooth, 4-rayed stars present both in the canal 

 walls and in the base. The following measurements in milli- 

 meters were taken : 



(a) Small, 4-rayed stars of the catial walls: 0.133 by 0.08; 0.11 by 0.08; 



0.1 by 0.076; 0.098 by 0.076. 

 (6) Small, smooth, 4-rayed stars of the base: 0.11 by 0.08; 0.083 by 0.08; 

 0.083 by 0.064; 0.08 by 0.083. 



The canal walls are thick. A large irregular axis is present 

 in the stem. 



Color, grayish green in formalin. 



Locality: Sabong Cove, near Port Galera, Mindoro. 



Type specimen No. C. 282 in the zoological museum of the 

 University of the Philippines. 



There is a single colony collected by Griffin at Sabong Cove,- on 

 the shallow reef, which is wonderfully rich in Alcyonaria. This 

 is the largest specimen of the species, and measures 80 mm. in 

 height and 50 mm. in breadth. The stem is somewhat bilaterally 

 compressed, measuring 20 mm. by 15 mm. in diameter. At a 

 point 35 mm. above the base the first branch is given off on one 

 side, the other side of the stem being barren to a height of 

 50 mm. The stem gives off in all 8 branches including the 2 

 terminal ones. The first branch, which is characteristic, breaks 

 up at a point 1 cm. from its origin into 3 secondary branches. 

 These in turn divide into 5, 3, and 3 branches, respectively, 

 which in turn divide into terminal twigs bearing one or more 

 lateral lobes about 3 mm. long and 2 mm. thick and a terminal 

 lobe about 7 mm. long and from 4 to 5 mm. thick at the base, 

 or form only a single terminal lobe. The club-shaped polyps — 

 slender at the base and enlarged at the tentacles zone, about 

 50 to a terminal lobe and 20 to a lateral lobe — are closely 

 packed, covering the entire surface of the lobes. The tentacles 

 and tentacle points are folded over the outer edge of the oral 

 surface making a regular 8-pointed figure, the central area 

 being uncovered. 



' Sabong Cove is the second small cove to the left of the eastern channel 

 of Port Galera Bay, Mindoro.
