NO. 7 OPINIONS 115 TO 123 7 



Scopoli subsequently used Biiliiiuis for a land snail similar in general shape 

 to the species he had formerly included, but afterward found to be generically 

 distinct. The name Bulinnis remained in universal use for this last group until 

 quite recent times. 



Dall, 1892, Trans. Wagner Free Inst. Sci., vol. 3 (2), pp. 334-335, thought 

 that Bitlimiis would have to be restricted to Helix tcntaculata, though he did 

 not expressly name that as its type. 



A similar view was taken by Pilsbry, 1895-96, Manual of Conchology (2nd 

 sen), vol. 10, p. 3, who wrote: 



"As Scopoli quotes the name as of Adanson, it has been surmised that 

 ' BuUmiis' was a typographical error for ' Buliniis.' Whether this was the case 

 or not would have absolutely no effect upon our use of the name, for (i) Scopoli's 

 group does not rest upon Adanson for its elucidation, nor does he refer to 

 Adanson's page or plate; (2) that it was a typographical error cannot be 

 proven; it may have been an emendation on etymological grounds and Scopoli's 

 subsequent use of the same orthography would show it to have been a deliberate 

 change; and finally (3) Adanson being pre-Linnean cannot prejudice properly 

 proposed post-Linnean names. 



"It would appear that Buliiiiiis Scopoli, by process of elimination, must re- 

 place the generic name Bitliynia." 



Kennard and Woodward, Proc. Malacological Society of London, December, 

 1924, vol. 16, p. 126, have reviewed the several opinions on Bulimus Scopoli, 

 concluding that " Biiliiiius was an obvious mistranscription for Biiliniis; it must 

 be treated as such, and discarded in future literature." 



It may be remarked here that if Bulimus be synonymized with Bulinus Adan- 

 son, its type will become Bulinus senegaloisis Mueller, and unless the name be 

 emended, it will displace the genus Bulinus O. F. Mueller, 1781, a name very 

 widely used in zoological and medical literature. 



Buli)ius O. F. Mueller 



Bulinus "Adanson" O. F. Mueller, 1781, Der Naturforscher, vol. 15, pp. 5 

 and 6. For four species: Bulinus perla (=^ Physa jontinalis (Linnaeus)), B. 

 turritiis, B. gelatinus, and B. senegaloisis (this last based upon Adanson's " le 

 Bulin, Bnlinns"). Type by tautonymy : Bulinus scncgalensis O. F. Mueller, 

 " le Bulin " of Adanson. 



The name Bulinus was introduced into binomial nomenclature by O. F. 

 Mueller. He states that his intention was to provide genera for the fresh-water 

 snails with two bristle-shaped tentacles with eyes at their inner bases. He sug- 

 gests that the " Tellerschnecken " keep the name Planorbis while Adanson's 

 name Bulinus could be accepted for the " Eyformigen." ' Of the latter, four 

 species were known to him. The Bulinus perla was fully described and figured, 

 and is recognized to be Physa jontinalis (Linn.). This species was designated 

 type of Bulinus by Hermannsen (i84''i, Index Gen. Alalac, vol. i, p. 140). 



' " So kann doch bis daliin, den .Schneckenliebhabern zu Gefallen. die den Be- 

 griff einer Tellerschnecke i^cy dem Eyformigen nicht ausstehen konnen, der 

 Name Tellerschnecke denen mit platter Schaale verbleiben, und die mit lan- 

 glichen Schaalen den Adansonischen Namen Bulinus annehmen." (1781, Der 

 Naturforscher, Halle, vol. 15, p. 6.)
