Sponges from Funafuti. 349 



P. Halli lie in the smaller size of the beams and meshes of 

 the network and in the characters of the loose spicules. The 

 type of the genus is turbinate in form, but it cannot be said 

 what would be the ultimate shape of the probably young 

 specimen of P. Hindei. 



locality. Beacon Island, Funafuti, 50 fath. 



Clathrina depressa (Dendy). 



1891. Leucosolenia depressa, Dendy (8, p. 65, pi. iii. figs. 4, 4 a, pi. viii. 

 fig. 8, pi. xi. fig. 4). 



The specimen forms a small whitish patch about 6 millirn. 

 in area on the surface of Luffariella variabilis. The dermal 

 triradiates are slightly larger than in specimens from Port 

 Phillip, being 240 x 25 fi, as against 200 x 28 p, from the 

 latter locality ; the quadriradiates are few in number and 

 with the apical ray almost aborted. 



Locality. Funamara, Falefatu, 25-45 fath. 



Distribution. Port Phillip, Victoria; Funafuti Atoll. 



Chondrilla mixta, F. E. Schulze. 

 1877. Chondrilla mixta, F. E. Schulze (23, p. 116). 



The one specimen forms a small bluish-black incrustation 

 on an Agaricia. The surface of the sponge is finely granular 

 to the naked eye. The spherasters are 25-30 p, in diameter, 

 with about 20 pyramidal prickles, and the oxyasters 24-28 p, 

 in diameter, with a centrum 7 p. in diameter. 



The spherasters just below the surface are united into little 

 heaps, which give rise to the granular appearance of the 

 surface ; the oxyasters are only very rarely present in the 

 ectosome. 



Locality. Funafuti Islet. 



Distribution. Java; Amirante Is.; Red Sea; Funafuti 

 Atoll. 



Corticum candelabrum, O. Schmidt. 



1862. Corticium candelabrum, O. Schmidt (21, p. 42, pi. iii. fig. 25). 

 1881. Corticium candelabrum, F. E. Schulze (25, p. 410). 



The specimen forms a small greenish-black disk, 3 millim. 

 in area by 1 millim. in thickness, attached to a piece of 

 coralline. 



Locality. Fuafatu, 50-70 fath. 



Distribution. Adriatic; Zebu; Funafuti Atoll.
