Leuconia glomerosa Bowerbank, 1873


Leuconia glomerosa Bowerbank, 1873 

Bowerbank (1873: 17) described a mass of coalesced tubes from Port Elizabeth. Subsequently, this same species was found in Western India, described by Dendy (1916) and in West Australia ( Row & Hôzawa 1931, not described). The skeleton is inarticulate and the spicules include a sheath of cortical giant diactines underneath a thin layer of small triactines, and supported by subcortical pseudosagittal triactines. The tubar skeleton is formed by the longest actine of the subcortical triactines and the unpaired actines of atrial triactines. The atrial skeleton consists mostly of triactines, but there are also relatively rare tetractines. The species has been reassigned to Heteropia glomerosa  by Dendy (1916).
