large quadriradiat.es of tlie dennal surface, the skeleton is 

 quite irregularly an-anged, consisting of scattered triradiate 

 spicules. On account of the large subdermal quadriradiates, 

 thougli the inwai'dly-directed apical ray is but short, i 

 propose to include the species in the genus Leucilla.

 the Heads, coll. J. B. Wilson) ; Freemantle, W.A. (Carter).

 '■ This remarkable species exhibits a singular irregularity in 

 external form, varying from com])ressed, irregularly-folded 

 plates to elongated C3dindrical tubes, and often attaining a 

 large size. It is common in Port Jackson, whence 1 have 

 received specimens from Professor Spencer, but I have only 

 seen a single specimen from Port Phillip, collected by Mr. 

 Wilson. 



The flagellated chani])ers are a])pr(jximately spherical, 

 scattered irregularly, about OOD mm. in diameter.* 



Localities. — Bass Straits (Hseckel) ; Port Jackson (von

The only s})ecimen of this sponge which I have seen is a 

 piece of the type from the British Museum, in which sub- 

 dermal quadriradiates, with long, inwardly-directed apical 

 ray, are abundant. I therefore include the species in the 

 genus Leucilla.

• Von Lendenfeld gives tbe diameter as 0-04 mm., but this is probably an 

 error, for ho also says that in Leucandra ti/pica tbe chambers "are smaller 

 than in any other ease, their diameter rarely exceeding 0-04 mm." (loc. cit., 

 p. 1130.
