" Con. Icon,, species 273. 

 1860. M. ericea, Pse., Proc. Zool. Soc. London, p. 146. 



The first specimens collected and forwarded to London were 

 in poor condition ; others found since leave no doubt as to the 

 above synonomy. 



MiTRA LUBRICA, Pse. 



1867. M. glabra, Pse., Am. Jour. Conch, p. 272. 



Name preoccupied ; changed as above. . 

 Cerithium piperitum, Sowb. 

 Thes. Con., species 76. 

 1854. C. alveolus, Jacq., Voy. au Pol. Sud., vol. 5, p. 105, pi. 

 24, f. 28, 29. 



Cerithium tuberculiferum, Pease. 



1865. C. Adansonii, Rve. non Bi'ug., Con. Icon., Sp. 11. 



The above species, collected by Mr. Cuming at the Paumo- 

 tus, is decidedly distinct from the one inhabiting the west coast 

 of Africa, described by Bruguiere as Adansoni. The figure and 

 description in Con. Icon, refer to the Polynesian species, which 

 I separated as above. 



Cerithium maculosum, Migh. 



Q. nassoides, Sowb., Thes. Con., Sp. 114. 

 1865. " Rve., Con. Icon., Sp. 97. 



The above synonym should be added on page 127 of my 

 previous paper.
