NOTES. 



Note, to correct the name Jousseaumia. — In the thirty-sixth 

 Supplementary Report on the Pearl Oyster Fisheries of the Gulf of 

 Manaar (part v, published by the Royal Society, 1906), I described under 

 the name Jonsseaumia a new genus of Eulamellibranchiate molluscs, 

 commensal along with the Sipunculid Aspidosiphon in the basal chamber 

 of the corals Heteropsammia Michelini and Heterocyatlms cequicostatus. 

 Since the publication of this paper my attention has been called to the 

 fact that the name Jousseaumia is preoccupied, and indeed has been used 

 twice over, once to denominate a subgenus of Cyproea (Sacco, " I Molluschi 

 dei Terreni Tertiarii del Piemonte e dalle Liguria," part xv, 1894) and 

 again as the name of a new genus of the Alpheidse (H. Couti^re, Bulletin 

 du Museum d'Histoire Naturelle, Paris, 1896, ji. 381). By a singular 

 coincidence the name in both instances was omitted from the Zoological 

 Record, and therefore does not appear in the Index. It is, I hope, 

 a sufficient excuse for my having fallen into the error of using a generic 

 name for the third time that I relied upon these two excellent guides in 

 questions of nomenclature. Under the circumstances a variation of the 

 termination seems preferable to the invention of an entirely new name, 

 and I therefore propose to substitute the name Jousseaumiella for that 

 originally given. G. C. Bourne. 



Correction. — In my paper " On the Anatomy of Tagelus gibhus and 

 T. divisus," p. 219, line 6 :— for " but both portions of the muscle are of 

 the same depth. In T. rufns the anterior is deeper than the posterior 

 part," read : " though both portions of the muscle are of the same depth 

 (in T. rufus the anterior is deeper than the posterior part)."
