476 ADDENDUM TO THE MONOGRAPH OF AUSTRALIAN SPONGES. 



for which I propose the name above given. Neither becomes 

 gelatinous when soaked in water, although when dry the brown 

 specimen presents here and there the appearance of dried glue, 

 which the dai'k specimen does not. I admit that this description 

 is not satisfactory; but under the circumstances it cannot be 

 otherwise ; at the same time it is desirable that it should be 

 recorded to induce future observation.

Teiciionella prolifera. Carter, 



In Annals and Magazine of Natural History, Sei\ 5, Vol, 15, 

 Nr. 89, p. 119, foot note. Carter gives a new locality for this 

 sponge, namely, Port Phillip, 



Teichonella labyrintiiica. Carter. 



In Annals and Magazine of Natural History, Ser. 5, Vol. 15, 

 Nr. 86, p. 119-120. Carter describes the ciliated chambers of this 

 species, and gives a new locality for it, namely, Port Phillip. 



The description of the canal system is very remarkable. The 

 chambers are cylindrical as in the Syconid^e, and there is one large 

 terminal inhalent pore, and one large exhalent pore on the other 

 end, likewise terminal. In no other sponge has it hitherto been 

 observed that the inhalent pore or pores was as large or anything 

 approaching the size of the exhalent pore, the Chamber Osculum. 

 This statement therefore must be received with caution. At the 

 same time Carter states that there are numerous small pores in the 

 wall of the cylindrical chamber. These are homologous to the 

 ordinary inhalent pores in the ciliated chambers of other sponges. 



I consider it as highly probable that these are actually the 

 inhalents, that inhalent canals exist between the cylindrical 

 chambers, and that there is no large vent at one end, or if there is 

 it is likewise an exhalent pore. 



Leucandra catapiiracta. Haeckel. 



An exceptionally slender specimen, measuring only 2 mm. in 

 diameter, has been obtained from Port Stephens (Australian 

 Museum), and this place has to be recorded as new locality for the 

 species.
