Genus LEMNALIOIDES novum 



Generic characters. — The colony is upright, treelike, or bushy, 

 and consists of a number of stems coalesced in one or more 

 groups for some distance above the base. The tubular, non- 

 retractile polyps are scattered singly or in little groups on the 

 branches and lateral and terminal twigs. The spiculation of 

 the cortex and the canal walls is similar to that in Lemnalia. 

 The tentacles contain a very few, very small, scattered spicules, 

 and the stomodseum contains no spicules. The tentacles bear 

 more than one row of pinnules, and show a median longitudinal 

 band of muscle fibers on their outer surfaces. The type of the 

 genus is Lemnalioides kiikenthali sp. nov. 



Lemnalioides kiikenthali sp. nov. (Plate I; text figs. 1 to 6). 



Type. — This species is described from a single well-developed 

 colony from one of the shallow reefs in Port Galera Bay, Min- 

 doro, No. C. 254, zoological collection, University of the Philip- 

 pines. Collected by S. F. Light in May, 1912. 



The colony, which is 115 mm. in height and 110 mm. in greatest 

 breadth across the polypary, arises from a small somewhat en- 

 crusting base, 38 mm. in length and 25 mm. in width. It consists 

 of 2 main stalks or groups of stems which divide at a height of 

 about 40 mm. to form a number of stems or main branches. 

 These are divided and subdivided toward their outer ends to form 

 a number of distally directed, closely approximated branches. 

 On the slender, lateral and terminal twigs of these branches 

 and scattered to some extent on the branches themselves are 

 the large, tubular, nonretractile polyps. They arise singly or 

 in little groups, and are all expanded in the type specimen 

 (Plate I), where they average from 1 to 2 mm. in length and
