Carter's (1) genus Hohpsamma is described as being ''without 

 fibre," a statement which although I consider it incorrect, I must 

 accept, as there are no figures or descriptions of details; one of the 

 species I believe belongs to this group. 



Also, Carter's Dysidea (2) cannot be placed in this group, as all 

 the fibres of his species seem to contain foreign bodies. 



Carter's species Coscinoderma lanuginosiini from Freemantle, 

 W. A., (3), and from Port Phillip Heads (4), might be comparHl)le 

 to Aulena. But I think it probably identical with a totally 

 different sponge, belonging to my Genus Euspongia of which I 

 possess specimens from Torres Straits, etc. 



Among the numerous species described by other well-known 

 authors on Spongiology, there are none which I could refer to this 

 Sub-family, which although doubtlessly belonging to the Spongidse 

 as described by Schulze (5), still shows so many peculiarities, that 

 a detailed description of the anatomy of some of the species consti- 

 tuting it, will be of interest.

Auleninse which consist of very thin lamella3. These are much 

 and irregularly folded, and form a honey comb- like lacunose struc- 

 ture. Outside the whole structure is enclosed by a lamella, 

 which is perforated by numerous large pores, and consequently 

 has a sieve-like appearance. This external covering lamella is 

 identical in structure with the internal lamellae, and appears as a 

 continuation of these. The pores of this external lamella lead
