PKOCEEDINGS OF THE MALACOLOGICAL SOCIEir. 



1. BULIMINUS (LEUCOTiENIUs) PrOCTERT, G. B. Sow.' 



Of this species I received three -well-preserved spirit specimens : 

 they Avere collected in N.E. Madagascar. 



The pulmonary chamber extends through about half the length of 

 the body-whorl. 



The salivary glands are aggregated in three main masses — an 

 anterior median one situated above the oesophagus, and a posterior 

 pair disposed laterally to the crop. 



The radula consists of about 170 rows having the formula 28*1 "28. 

 The central tooth is bicuspid, with a vestige of a third median cusp 

 (Fig. VI.). The lateral teeth are very uniform, except that at about 

 the sixteenth row they become less well developed, while the outer 

 cusp becomes a little more marked. 



The lower part of the upper segment of the hermaphrodite duct is 

 provided with thin-walled diverticula ; a portion of this region has 

 been prepared for histological investigation, but examination of the 

 sections is not yet completed. 



2. BULIMULTJS KOPELLI, G. B. Sow." 



The specimens (from Bogota) of this species which were examined 

 by me consisted of the fragmentary remains of three individuals. 

 They were in a bad condition, as may be imagined from the fact that 

 they had died and become dried up in their shells, and had only 

 been soaked out long subsequently ; moreover, a pin had apparently 

 been rather freely used in the process of extraction : however, 1 was 

 enabled to make out pretty satisfactorily in one of them the points 

 shown in the following figures : —
