this time nominating conulus " Pfr." (a slip of the pen for Rve.) as 

 genotype. 



In 1914 Gude * rejected Conulinus Mts. on account of the earlier Conulina 

 Bronn, 1835, substituting the name Edouardia, with conulus " Pfr." (another 

 slip of the pen for Rve.) as type. 



As doubt existed both as to whether Conulinus Mts. was valid and 

 whether conulus was available as genotype, the matter has been submitted 

 to the International Commission on Zoological Nomenclature, whose decision 

 is that " Conulinus von Martens, stands, with genotype Bulimus conulus 

 Reeve." Edouardia Gude must thus be placed in synonymy.

1849. Bulimus conulus Rve., Conch. Icon. pi. 78, fig. 577. D.F. 

 Hab. L. Marques. Rikatla (Junod). 



I have been unable to verify the truth of this record ; Reeve's rare 

 species has often been raisideutified, and this may be a case in point.

I have been unable to verify either of these records, but do not doubt 

 that that of Sturany refers more nearly to nieridionalis than to natalensis.

A coastal species described from Zanzibar and known as far north as the 



Shimbi Hills, Kenya Colony (Kemp). Owing to confusion in the Gibbons 



collection, as represented in the British Museum, wherein 3 different species 



were labelled as types of C. tumidus, I have referred the matter to Mr. J. W,
