Thi.s species seems to live in the whole East-Indian Archipelago, which was explored 

 by the Siboga. On some stations it was very abundant. 



Some specimens exhibit a brown spot on the last whorl of the shell, just above the 

 aperture. Besides, the animals differ a little in size. 



I have not found the "lame vitree", mentioned by Souleyet ^). 



The animal has no dorsal lobe on the fin.

Limacina lesueurii has been found off Batavia (Bo.-vs) ') and again by the Challenger 

 Expedition 2°56'N., 134° 11' E. (north of New Guinea). However, the Siboga did not succeed 

 in finding it again. 



As I had no occasion to study any specimen I cannot say whether d'Orbigny is right, 

 who erected a new species for his Atlanta rottmda *). The figures of the shell indeed seem to 

 refer to Limacina lesueurii^ and perhaps it is only a variety of the type, as Souleyet ") 

 regarded it. But d'Orbigny says in the text, that the shell of Atlanta rotnnda is "a peine 

 ombiliquée", and the margins are "épais"; the operculum "circulaire, formé de lignes
