The canals are numerous and fairly large, their diameter being 

 several times the thickness of the canal walls and their walls 

 contain numerous spicules. In the center of the stem of some 

 colonies there has been observed a thickening of the canal walls 

 at the expense of the canal spaces and a decrease in the number 

 of canals resulting in the formation of a thickened region ap- 

 proaching the irregular axis found in C. ramosa sp. nov. 

 (see p. 450). 



The color of the colony in specimens preserved in formalin 

 is characteristically a light green shading into gray or brown. 

 In life the colonies are greenish brown. 



Localities: Bantayan Islands; Port Galera Bay, Mindoro; Si- 

 langa Channel, Taytay Bay, and the Pabellones Islands, Palawan. 



Type specimen, No. C. 2300 in the zoological museum of the 

 University of the Philippines. 



The alcyonarian collection of the zoological museum of the 

 University is very rich in colonies of this species of Capnella. 

 There are 50 specimens in all, including specimens from each of 

 the regions of the Philippines where systematic collections have 

 been made; that is, from the northern end of Mindoro (Port Ga- 

 lera Bay and Sabong Cove), from the Bantayan Islands (Doong 

 Island), and from the northeastern coast of Palawan (Taytay,
