(a) Spindles — Continued. 



(3) Slender, curved, spindles without central enlargement: 0.266 by 



0.036; 0.21 by 0.03. 



(4) Thicker more heavily spined spindles without central enlarge- 



ment: 0.277 by 0.06; 0.28 by 0.06. 

 (c) Irregular forms: 0.095 by 0.057; 0.17 by 0.095. 



The stem cortex contains many short thick spindles, usually 

 constricted in the middle, with rather high narrow warts. The 

 following measurements have been taken: 0.155 by 0.055; 0.137 

 by 0.074; 0.133 by 0.08; 0.127 by 0.066; 0.11 by" 0.06; 0.11 by 

 0.064. Besides these there are scattered, irregular, club-like 

 bodies of which the following measurements have been taken: 

 0.125 by 0.076; 0.1 by 0.08; 0.087 by 0.045; 0.08 by 0.068. 



The spicules of the canal walls are thick, heavily warted 

 spindles somewhat similar to those of the stem cortex and a few 

 thick, irregularly knobbed and warted club-like bodies. The 

 following types and measurements have been noted : 



(a) Short thick spindles with a central constriction and 2 zones of warts: 



0.16 by 0.09; 0.155 by 0.1; 0.133 by 0.095. 

 (6) Long irregularly warted spindles: 0.2 by 0.1; 0.18 by 0.098. 

 (c) Irregular knobbed club-like forms: 0.133 by 0.107; 0.12 by 0.079; 0.095 



by 0.08. 



The thickness of the canal walls is several times the diameter 

 of the canal, but there is no central axis. 



Color of colony in formalin, brown with a grayish tinge on 

 the polyps. 



Locality : Tide channels in the reef at Doong Island, Bantayan 

 Islands. 



Type specimen No. C. 269 in the zoological museum of the 

 University pf the Philippines. 



I have named this new species from two small but perfect 

 colonies collected by Griffin and Wharton at Bantayan in 1909. 

 The largest of these (Plate I, fig. 8) is 32 mm. in length, and 

 consists of a rigid stem portion 5 mm. in diameter which passes 

 into the polyp-bearing portion of the colony at a point 20 mm. 

 from the base, giving off 4 short branches in a sort of whorl. 

 These measure, respectively, 8, 4, 3.5, and 2.5 mm. in length, 

 the first two bearing 4 lobes each, the other two bearing each 

 a single terminal lobe. The main stem beyond this whorl gives 

 off 4 catkin-like branches, and ends in a compound catkin. In 

 this colony, as in C. ramosa and C. philippinensis var. albida, 

 there are scattered polyps on the main stem and branches. 



The thick canal walls containing numerous spicules make the 

 colony very stiff and rigid. The canals are regularly distributed
