This very beautiful sponge is well represented in the 

 collection. All the specimens which I have seen, six in 

 number, are more or less compressed, in the case of large 

 specimens veiy^ much so. The finest specimen is GO mm. in 

 height by 50 mm. in greatest breadth. Von Lendenfeld 

 repi-esents the radial chambers as being perfectly straight 

 and unbranched, whereas, in the Victorian specimens, they 

 l)rancli ie))eatedly, the branches running parallel with one 

 another to the dermal surface. This may possibly constitute 

 a specific difference, but I am more inclined to think that 

 the tigui-e leferred to is incorrect. 



Localities. — Port Jackson (von Lendenfeld) ; near Port 

 Pliillip Heads (Carter, and outside the Heads, coll. J. B. 

 Wilson).

In an;itomical chaiacters this species closely i-esembles 

 G. sacca, but differs markedly in external appearance and in 

 the less regularly arranged tubar skeleton, which, though 

 composed of slender spicules, is very dense and confused. 

 The suiMlermal sagittal triradiates, with inwardly directed 

 basal r; y, are not mentioned by Mr. Carter; they are clearly 

 present in my specimens thougli less obvious than in G. 

 sacca on account of tlie somewliat confused character of the 

 tubar skeleton. The oxea of the dermal tufts are straight, 

 or only very slightl}^ curved. The manuscript illustration 

 which Mr. Carter has kindly sent me shows only a very 

 slight curvature, though he describes them as " curved." 

 The species is abundant in the collection. ' 



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

 1 and outside the Heads, coll. J. B. Wilson) ; King Island 

 (coll. Prof Sjiencer) ; Holiart, Tasmania (coll. A. Dendy).
