XXVIII. — Supplement to the Descriptions of Mr. J. Brace- 

 bridge Wilson^s Australian Sponges. By H. J. Carter, 

 F.K.S. &c. 



[Plate X.] 



Having finished the description of Mr. J. Bracebridge 

 Wilson's Australian Sponges which came to me in his first 

 consignments, I have now to add in the following " Supple- 

 ment " descriptions of those which have been received since, 

 and further to supply any omissions and corrections that may be 

 necessary in what has already been published, including 

 replies to objections that have been made to any parts of the 

 latter. 



Taking the orders again as they stand in my Classificatory 

 Arrangement of 1875 (' Annals,' vol. xvi. p. 131 &c.), I would 

 observe that the plan adopted latterly in my descriptions of 

 these Australian Sponges, viz. that of inserting a copy of the 

 tabular view of this arrangement for more convenient reference 

 at the commencement of each order, was omitted in the 

 Carnosa and Ceratina ; hence this will now be supplied. 



Order I. CARNOSA. 



Fam. 1. Halisarcida. 



Char. Possessing no spicules. 



Fam. 2. Gumminida. 



Char. Possessing spicules. 



I also omitted to note what I had written on the subject, 

 viz. a paper on all the then-known species of Carnosa, in the 

 ' Annals ' of 1881 (vol. viii. p. 241 and "Addendum," p. 450).
