The following specimens, in the Collection of the University Museum of Zoology, Cambridge, 

 are referred, somewhat doubtfully, to the same species : 



Japan, from rooting spicules of Euplectella marshalli, Prof. K. MlTSUKURI, Reg. Sep. 23, 1S96. 



Queensland, Port Denison (two slides), Miss E. C. JELLV, Reg. May 24, 1S95. 



Queensland, Port Denison, from remains of the Collection described by Prof. W. A. HASWELL, 



Australian Museum, Sydney, Reg. Oct. 23, 1899. 

 Lifu, Loyalty Islands, A. WlLLEY Collection, Reg. Mar. 1, 1898 (determined by Miss Philipps 



as E. delicatula Busk. 

 Torres Straits, 132, 190. A. C. HADDON Coll., Reg. Feb. 24, 1898. 



Zoarium consisting of delicate branches. Zooecia small, the peristomes long and prominent; 

 usually about four series visible in one half of the branch. Ovicell more or less pyriform ; if 

 present at a bifurcation extending into one of the branches only : its roof not traversed by 

 zooecia. Ooeciostome terminal, with a transversely elongated ooeciopore, bounded by lips which 

 are variable in their development. 



If the specimens of which a list is given above are correctly referred to one species, 

 there is a considerable amount of variation in the characters. The branches and the zooecia 

 are much slenderer than those of E. proboscidea, as is seen by comparing fig. 1 1 with fig. 1 2 

 (both drawn to the same scale). In one or two cases, particularly in the specimens from 

 Queensland, some of the branches are very straight; and, except for the projection of the 

 peristomes, cylindrical in form '). In others, as in 376. L., these features are not so pronounced. 

 The peristomes are usually long and slender. The ovicell differs from that of the species next 

 to be described in not having its roof traversed by zooecia ; although some of the peristomes 

 at its sides may be laterally adnate to its roof. 



The ovicell, although variable in shape and in its position with relation to a bifurcation, 

 appears to have some features which are fairly constant. If developed in the region of a 

 bifurcation, it does not divide with the branch, but extends into only one of the branches (fig. 1 1). 



1) These specimens appear to resemble Pustulipora fragilis Haswell (1. cit.).
