myself seen specimens from Australian seas. Yon Lenden- 

 feld* states that all the specimens in Australian waters are 

 cylindrical and must be referred to Hseckel's variety lohata, 

 which he j)i-oposes to erect into a species under the name 

 (iraittki lohata. Carter-|- simply records Grantia conprcfisa 

 amongst Mr. Wilson's sponges, and also a tubular variety 

 which he terms fistulata, and which is probably identical 

 ^^ ith von Lendenfeld's lohata. 



T include the species in the genus Sycon on account of the 

 tufts of oxea which crown the radial tubes. The dt-rmal 

 cortex is ver}^ thin. 



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

 Piiillip Heads (Carter).

I have already given a detailed account of the history and 

 anatomy of this remarkable species in my memoii' " C)n the 

 Anatomv of Grantia lahijrintltica. Carter, and tlie so-called 

 Family Teichonidte," published in Vol. XXXII, N.S., of the 

 Quarttn-ly Journal of Microscopical Science. The species 

 appears to l)e fairly common near Port Phillip Heads, the 

 largest specimens which I have seen measure no less than 

 live inches across the top, a truh' gigantic size for a single 

 Sycon individual. 



Localities. — Fremantle, W.A. (Carter) ; near Port Philli}) 

 Heads (Station 5 and outside the Heads, Carter and coll.

Solitary, sessile, sac-shaped, broadest below and tapei'ing-

 single specimen is markedly compressed, and measures 25

 t!ie sac is not much more than 1 mm. in thickness and the 

 gastr.il (^•lvity is correspondingly spacious. The dermal
