1 This genus was instituted doubtfully by Bovallius to receive the single species Hyperia cuspidata, Streets, but as the species in question 

 belongs, I think, clearly to the genus Paraphronima, Clans, the name Cyllias will not be needed. 



■ On p. 514, 1. 11, for Cyproidia read Cyproidea. The latter form is given in the Annals and Magazine of Natural History for January 1880, but 

 precedence mayperhaps be allowed to the form Cyproidia, which in the same year 1880 appears in the Proc. Linn. Soc. N. S. W., since Mr. Haswell 

 would have had the opportunity of correcting the press in Australia but not in England. 



3 For Dactyloccrus, p. 184. line 6, read Daetylocera. 



•* In 1S49 Milne-Edwards and J. Haime, Comptes rendus, t. xxix. p. 261, gave the name Dania to a genus of fossil Corals ; this name they spell 

 Danaia in the general index to their Monograph of the British Fossil Corals, Pahcont. Soc. vol. for 1854, published 1855. Danaia, Spence Bate, 

 must therefore give way to the later Cressa, Boeck, with which a specimen of the type species, recently obtained and dissected, proves it to be 

 certainly synonymous. Compare the earlier footnote, p. 747.
