 Phyllospongia dendyi, var. digitata, Lendenfeld, Mon. Horny 

 Sponges, 1889, p. 178. 



Two examples of this variety were obtained at Lake Illawarra. 

 There are numerous specimens in the Museum. At Jervis Bay it 

 is fairly common about low-tide line. 



The sponge is more or less frondose in habit, and usually con- 

 sists of numerous lamellae and digitate processes. One specimen 

 is 120 mm. high, 100 mm, broad, and the main lamina is 5 mm. 

 in thickness. The surface is minutely conulose, with many 

 scattered pores, about 0*5 mm. in diameter. In the deep folds of 

 the lamellae, and also between the digitations, a moderate number 

 of circular openings are present, measuring from 1 to 5 mm. in 

 diameter. The main fibres are uneven, trellis-like, and cored with 

 abundant spicule fragments and small sand grains. 



Specimens from Western Australia are generally more regular 

 in form and the lamellse somewhat thinner than iti the variety 

 digitata, Lend., and agree closely with the description and figure 

 of P. dendyi, \ax. Jrondosa, Lendenfeld.
