274 On the French /Sjpec/es q/' Geomalacus. 



It only remains for me to add a few words, in order to dispose 

 of the remainder of Mabille's species, created only to swell the 

 above-mentioned monograph. These are designated: — Geoma- 

 lacus Andrewsi, Mabille ; G. angmfornus, Morelet ; and G. in- 

 termediusy Normand. Allman, Andrews, and others repeatedly 

 name a white-spotted variety, the same which in my treatise 

 "Ueber Geomalacus'''' (Malacozool. Blatter, 1873), with draw- 

 ings, I called var. AUmanm, in contradistinction to tlie more 

 frequently occurring yellow-spotted variety, which is the typi- 

 cal form. Andrews calls the white-spotted form simply " the 

 white variety ;" and on this white variety (it should be white- 

 spotted variety) Mabille writes as follows: — "Cette nouvelle 

 es^D^ce, que nous dedions a Monsieur William Andrews de 

 Dublin, et que tons les auteurs Anglais ont confondue avec le 

 maculosits, se distingue de cette esp^ce par un corps blanchatre, 

 parseme d'une multitude de petits points noiratres. C'est I'in- 

 verse chez l'esj)l'ce precedente [maculosus).'''' He evidently mis- 

 construes the original meaning ; and the result is the new species 

 Andreiosi. Jeffreys, in liis 'British Conchology,' says, "I sus- 

 pect that the Limax anguiformis of Morelet (Moll. Port.) also 

 belongs to the present genus, if, indeed, it is not the same 

 species as ours." This simple notice suffices to settle the 

 Geomalacus anguiformis, Morelet, whose specific diagnosis is 

 any thing but improved by the all but useless drawing of 

 Morelet. Finally, Normand ascribes to his Arion intermedlus 

 an internal shell ; and thus we obtain a Geomalacus inter- 

 medins, Normand. 



It is to be regretted that the rubbish of synonymy is thus 

 needlessly multiplied to an extraordinary degree by such in- 

 genuity in creating new species and even new genera — on 

 which head see other reports. 



Franlifort-on-Maine, January 1873. 



The preceding short treatise was sent to me by D. F. Hey- 

 nemann, Esq., with a request to publish a translation of the 

 same in the ' Annals,' if deemed of interest on this side of the 

 Channel. Having consulted J. Gwyn Jeffreys, Esq., F.Ii.S., 

 &c., and obtained his affirmation on this point, I have much 

 pleasure in submitting Mr. Heynemann's discussion to 

 British malacologists, and beg to observe that in translating 

 Mr. Heynemann's report from the original German I have 

 adhered as closely to the sense of his delineations as is con- 

 sistent with clearness and intcUigibleness, and must refer those 

 who wish to read the original to the ' Malacozoologische 

 Blatter,' where Mr. Heynemann's monograph on the genus 

 Oeomalacns will appear witli drawings.
