ON THE ANATOMY OF BULIMUS 

 SINISTRORSUS, DESHAYES. 



Bv WILLIAM MOSS anl WILFRED MARK WEBB, F.L.S. 

 (PLATE I.) 



In an article " On the generic position of Bulinms gakriciilum, 

 Mouss.," contributed to the " Nautilus " for February last, Mr. 

 Pilsbry points out that this species is the type of the section 

 Pseiidopartula of Pfeiffer, and he includes in the same section 

 Ariophanta dohertyi, Aid., and Helix nasuta, Mete, leaving out 

 " the New Caledonian species grouping around B. sinistvomis, 

 Desh.," placed in this position by Pfeiffer, and suggesting 

 Montrouzier's name of Drapariiaiidia for them. 



This grouping is based upon purely conchological characters, 

 as Mr. Pilsbry is in doubt as to the systematic position of 

 Pseiidopartula, and says that " in the absence of information upon 

 the soft anatomy, the group might be placed either next to 

 Papiiina in Pielicidae, or in the Bulimulidae, or the Zonitidae." 



As a contribution to the knowledge of the anatomy of one 

 of the species originally included in Pseiidopartula, the following 

 brief notes on B. sinistrorsus, with the accompanying figures, are 

 given as simple facts, no attempt being made by the writers to 

 fi.x the place in classification, of either species or group. 



The material for the present work, in the shape of several 

 spirit specimens of Biiliiniis sinistrorsus was received by one of 

 the writers (Mr. Moss) some years ago, through the kindness of 

 Mr. and Mrs. Hadfield, who had collected the snails in Lifu, New 

 Caledonia. 



The remarks on the various organs made out, will ba found 

 under the heading of " Explanation of Plate I " on the following 

 page.
