HISTORY. — Ariiin siihfiisciis (fiub/iisnis, 

 brownish), was first clearly ilosrribeil 

 and fi.ffured by l)ra])arnaiiil, in l.^O.V 

 altliongli there seenrs reasons to believe 

 tliat the Limit, r fiisrus ami L. riiictiin of 

 ^liiller belong to the same .species. 



In this country, A. su/i/iisms was long 

 confounded with A. nfer, or re.garded as 

 a variety or immature form of that spei-ies, 

 Herr D. F. Heynemann being the tii'st to 

 jiublisli it as British, in ISS.'j, altlioueh 

 lirior to tliat date Mr. Roebuck, with the 

 assistance of the late i\Ir. Ashford, liad 

 identified it as a native of this country. 



]\Itj(|uin-Taudt)n, also, did not idearly 

 distinguish this species from his Arimi 

 rii/us, as may be seen on examining his 

 figure of the reproductive oigans ascribed 

 to that species (Hist. Moll. France, pi. 1, 

 f. li!j. The shape and chai'acter of tlie free 

 oviduct and the pioint of fixation of the 

 retractor axe undeniably tliose of A rimi 

 .•<iil)/ii.<<ri/.-<, while the absence of the lar^e 

 \'estil)ular pr(.)tulierance so characteristic nt 

 ^1. iifi'r, is convincing testimony that the 

 ^ hgui'e is ba,sed upon ,1 dissectnm of an 

 ^^^ — individiial of the piesent species. 



Witli this species the name of Dr. Aug. Bau(h;n, of Mouy, France, is 

 associated, in token of appreciati(jn (jf the merits of his work, "M('m(jire 

 sur les Limaciens da Departement de r(.)ise," and of the numeirius other 

 valuable malacological treatises (jf which he is the author,
