Under this name Deshayes has figured a shell in 

 Belanger's voyage (Ind. Orient. Zool. p. 419, Moll, 

 pi. 1, f. 14, 15) which differs remarkably from the ordi- 

 nary type. Our figure 10 is from a rather uncommon 

 variety.

Tanks near Calcutta ; Kondooruwave, &c. 

 This shell was fairly figured by Chemnitz as the 

 Tranquebar variety of the Helix vivipara of Linnseus. 

 The P. dissimilis of Eeeve was not Indian, but from the 

 Nile, and is not unlike unicolor ; his melanostoma (C. 

 Icon. Pal. f. 27) is regarded by Martens as a form of 

 this species. 



5. P. Bengalensis, Lamarck, var. gigantea. — P.

A swollen form of this widely difiused species.

 var. decussatula, or P. decussatula, Blanford, Proc.

Ava ; Eangoon. 

 Comparison of the types shows their absolute identity. 

 The specimen originally described was supposed to have 

 come from Central Africa. The spire is usually eroded.

 Benson), Abbild. N. Conch, vol. 2, p. 134, Palud. 

 pi. 2, f. 3. 



Jounpore, Soobathur, &c. 

 We are aware that Benson supposed "Eemossii" 

 was an incorrect reading of his manuscript name 



" prsemorsa," yet as the species actually published 

 under the latter designation by Eeeve is much more 

 like dissimilis, and the shell here delineated was the 

 melanostoma of Hutton according to Benson's collec- 

 tion, we prefer to retain the printed name. It matters 

 little, indeed, to science whether or not a Monsieur 

 Eemosse ever existed ; much to science that published 

 names should not be changed without the most absolute 

 necessity. The P. melanostoma of Eeeve (?= dissimilis) 

 does not exhibit the dark-lipped mouth ; no definition 

 of Hutton's shell has, to our knowledge, appeared in 

 print.
