MELANIID^. 279 



var. thiarella, 



Melauia thiarella, Lamarck, Hist. 1822, " Les Orandes Indes." 

 1 Mauritius ; coll. Mons. Lienard [A. S. B.]. 

 Agrees with M. Brot's pi. 29, fig. 3. 



7 Mauritius ; coll. Messrs. J. Caldwell and Lienard [A. S. B.]. 



Larger ; some agree witli fig. Id., some with fig. 3B., and 

 others again are intermediate. This variety Dr. Moerch con- 

 sidered as a distinct species and identified it as the " Stromhus 

 coactus" of Meuschen, 1787 [Hab. ?]. 



86. Melania [Tiara] cybele. 



Melania cybele, Gould, P. Bost. S. 1847, Fiji, Navigators' Islands, S{c. ; fide 

 Brot,-=^M. crenularis, Deshayes, Mag. Zool. 1844, Philippines. 



I doubt if Mel. dtadema, Lea, from the Philippines and 

 Ambojna, should be specifically separated. Dr. Mcerch consi- 

 dered Mel. crenularis as distinct ; he does not mention either 

 Lea's or Gould's species. 



3 Fiji ; ex c. G. Nevill, Esq, 

 Well represented by M. Brot's pi. 29, fig. 2B. 



var. amara. 



Melania amara, Moerch, J. de C, 1872, Little Nicobar,for Mel. miira. Reeve 

 [not of Meuschen^, Sumatra. 



1 Great Nicobar ; coll. F. A. de RoepstorfF, Esq. 



Apparently very local, as I have only seen two specimens 

 from the interior of the island. It is a beautiful form with 

 pink-tinged coUumella, and is exactly represented by M. Brot's 

 pi. 29, fig. 2 C. [" 31. diadema," Lea]. The writer classes Mel. 

 amara as a synonym of Mel. cybele ; doubtless he had not seen 

 an authentic specimen. Reeve's figures 175 b. c. from Sumatra, 

 though larger, are also very close. 



87. Melania [Tiara] winteri. 



Melania winteri (u. d. Busch), PMlippi, Abb. I, 1845, Java ; fide Brat 

 tgpe of his section Tiaropsis. 



8 Mauban ; Luzon ; coll. R. Hungcrfcrd, Esq.
