It is surprising no more synonyms of this species have ap- 

 peared. It varies widely in size and color. The variety de- 

 scribed by Mr. Dohrn, is the largest, and occurs not only at the 

 Hawaiian Islands, but also at the Paumotus and western Poly- 

 nesia. 



It is mentioned by Mr. Reeve and ale o Deshayes. The crena- 

 tion of the outer lip, although not included in former descrip- 

 tions, is well marked on the figures, especially that in Conch. 

 Icon. 



I would here remark that, with one exception, all the species 

 of Mitra described by Mr. Dohrn in Proc. Zool. Soc. 1860—61, 

 from the Cumingian collection, were dredged from Honolulu 

 Harbor, buried in mud and sand several feet, together with a 

 number of species of other genera. All the specimens obtained 

 were remarkably well preserved, excepting in color, which was 

 faded or altered. Several species of Cyprcea, obtained at the 

 same time, were about to be described as new, which was fortu- 

 nately prevented by Dr. Gray, in a note published by him in 

 Ann. Nat. His., July, 1858. The specimens were forwarded to 

 Mr. Cuming, by the late Dr. Frick and myself. 



The only species of Mitra decided to be new were approxima- 

 ta, Pse., Bella, Pse., and pudica, Pse. 



Several of the species I suppose to be extinct and others 

 were abundant, which are very rarely met with at any other 

 locality.

When perfect, the longitudinal ribs (on Hawaiian specimens) 

 are of a light orange yellow and interstices black. The transverse 

 striae are punctured, which I find to be the case with specimens 

 from other localities, though not mentioned in descriptions. The
