find it to be a bleached frap;mentary odd valve of the South 

 African Kraussia rubra. Professor Siiess gives Kraussia as one 

 of the types of the Corean waters^ on the authority of Mr. Da- 

 vidson, adding that the original habitat given by Mr. Adams 

 and myself, in the * MoUusca of the Voyage of the Saraarang/ 

 for T. Capensis (now Kraussia Deshayesii) (" Cape of Good Hope, 

 dredged at the depth of 120 fathoms "), is probably erroneous. 

 The Cape of Good Hope is especially the home of the Kraussice ; 

 the only species out of that locality is an abnormal one, K. 

 Lamarckiana, a native of South Australia and New Zealand. 

 Mr. Davidson^s mistake in giving Corea as the habitat of Kraussia 

 Deshayesii arose from a displacement of tickets in Mr. Cuming's 

 cabinet. I mention these instances, not with the view of cast- 

 ing disparagement on Dr. Suess's philosophy, but as exemplify- 

 ing the inconvenience of going into philosophical dissertations 

 before the materials have been thoroughly sifted and verified. 

 The specimens which have come under my notice (and I have 

 examined some hundreds, embracing every form of apophysis 

 hitherto known) are from the Paris Museum, kindly forwarded 

 to me by M. Valenciennes, at the suggestion of Professor Milne- 

 Edwards, and from the fine collections of the British Museum, 

 Mr. Cuming, Mr. Lombe Taylor, Mr. Metcalfe, and Mrs. De 

 Burgh.
