VaT.=^Oassis turgida. Reeve, Con. Icon. ff. 25 a-c. 



Hab. Samoa or Navigators' Islands (typical form in B.M.); 

 Mozambique, Red Sea, Andaman Islands (vars. torquata in B.M.) ; 

 New Holland (Reeve) ; Zanzibar (Kirk). 



The Buccinum nodulosum of Gmelin was founded on Schroter's 

 figure referred to above. The shell there represented is the counter- 

 part of the three specimens in the Museum from the Navigators' 

 Islands, presented by Her Majesty the Queen in the year 1841. 

 They correspond with the figure in every particular — the form, the 

 nodose whorls, the greatly thickened lip with the tubercles along 

 the margin, and the crenulations within are precisely similar. 



The nodose variety of C. torquata has the outer lip rather less 

 thickened and the crenulations or lircS within it less developed. 



The stunted form of C. vibex (Kiister, Conch.-Cab. pi. 51. ff. 5, 6) 

 differs in having tubercles only at the anterior part of the labrum 

 which is not Urate within ; it also appears to have no dark spots 

 around the base of the body-whorl. 



89. DoLiuM cuMiNGii, Hauley. 

 Hab. Philippine Islands, Wide Bay. 



90. DoLiUM MACULATUM, Lamarck. 

 Hab. Ceylon, Andaman Islands, &c. 



91. DoLiuM OLEARiUM, Bruguicre. 



Hab. Ceylon, Mauritius, and other parts of the Indian Ocean ; 

 Red Sea (Dunker). 



92. DoLiuM LUTEOSTOMUM, Kiister. 



Hab. Japan {Dunker, Schrenck, Lischke, Brit. Mus.). 



This species has been shown by Lischke to be the same as 

 D.japonicum of Dunker. D. favannii, Hanley, is also the young 

 state of this species, which, however, I am rather inclined to think 

 has not been satisfa(;torily shown to be distinct from D. varie- 

 gatum.
