Discussion.' — 



(i) The statement by von JMartens, 1895, that B. (Conulhms) 

 ugandae is " verv^andt mit B. comilus Rv." is equivalent to saying 

 that B. conulus Reeve is allied to B. (C) ugandae; and by that must 

 be meant that B. conulus Reeve belongs to the new subgenus Conu- 

 linus. No more is said about B. conulus because von Martens vi^as 

 describing new^ species and not revising old ones. 



(2) We have, then, given four syn-genotypes of the subgenus 

 Conulinus Viz. B. ugandae, B. hildebrandti, and B. metula, all new 

 species, and B. conulus the well-known species of Reeve. 



(3) If attention be confined for the moment to this paper (1895), 

 anyone selecting a genotype would fix on B. conulus Reeve for two 

 reasons : 



(a) As the common well-known species, reference to which 

 is dragged in by the author with the obvious purpose of explain- 

 ing his new subgenus ; 



(b) As bearing the trivial name on which the subgeneric name 

 is, without any doubt, based. 



(4) The correctness of this conclusion is proved by von Martens* 

 own action (1897) in fixing B. conulus as genotype. 



(5) Conulinus von Martens is not preoccupied by Conulina Bronn ; 



(6) But, whether as Conulinus or as Edoimrdia, Gude (1914) 

 confirms B. conulus as genotype. 



(7) There is accordingly no difficulty in following the action of 

 previous authors and retaining B. comthis as genotype. 



The answer therefore is : 



Conulinus von Martens stands, with genotype Bulimimis conulus 

 Reeve. 



The foregoing case has been studied for the Commission indepen- 

 dently by Dr. Wm. H. Dall, by Dr. Paul Bartsch, and by the Secre- 

 tary, and all agree with the foregoing findings.
