the most beautiful and interesting sponges which I have

 Natural History, August 1886, p. 135. 



I identify with this species a single specimen collected by 

 Mr. Wilson and a number of very beautiful examples sent 

 to me from Port Jackson by Mr. T. Whiteiegge. As pointed 

 out by Mr. Carter, the species closely resembles Schmidt's 

 Ute glabra, having the same characteristic silvery sheen on 

 the surface, due to the presence of the huge, longitudinally 

 disposed oxea. The Port Jackson specimens are shortly 

 stipitate and one of them consists of two individuals united 

 below for about half their length, or one might regard it as 

 a branched individual. 



Localities. — Near Port Phillip Heads (Carter, and Station 

 14, coll. J. B. Wilson) ; Watson's Bay, Port Jackson (coll. 

 T. Whiteiegge).

This species is also very similar to Schmidt's Ute 

 fjlabra. Although the skeleton is, as PoJejaefF points out, 

 " inarticulate," there are no subdermal sagittal triradiates 

 with inwardly directed basal ray. From personal examina- 

 tion of Polejaeff 's type I believe this species to be quite 

 distinct from Ute syconoides, the latter differing, amongst 

 other things, in its much longer radial chambers, with many- 

 jointed tubar skeleton, and in the much slenderer and less 

 densely packed longitudinal oxea. 



Locality.— Oft' Twofold Bay (Polejaeff). 



25. Ute ."ipicidosa, n. sp. 



Sponge colonial, consisting of a number of individuals 

 (about twent}^ in the specimen under examination) united 

 together by their bases so as to form a spreading colony. 

 The individuals composing the colony are sessile, ovoid, 

 narrowing above to the small terminal osculum, which has
