Memoirs of the Asiatic Society of Bengal. Zoological Results of a Tour in the Far East

The uteri (u) after running closely along the pharyngeal pocket on both sides unite with each other and form the unpaired uterine duct (uu) in the neighbourhood of the hind end of the main gut ; the duct soon joins the median egg-canal (ec). [...] Digestive System.—The mouth opens into the centre of the pharynx which is somewhat less than one-third the length of body and is placed somewhat in front of the middle of the body. [...] The egg-canal proceeds backward to enter the medial part of the accessory vesicle which seems to present features similar to those of the same organ of the preceding species. [...] The two species belong to two different genera and families of the Monaxonelida one to the genus Reniera of the family Haploscleridae the other to the pecliar and somewhat anomalous genus Amorphinopsis which is assigned provisionally to the Axinellidae. [...] II of this volume are due to the burrows of a mollusc in the wood below the sponge and do not open into the interior of the sponge which merely grows round them.
