FOREIGN VARIETIES OF BRITISH LAND AND 



FRESHWATER MOLLUSCA. 



By T. D. A. Cockerell. 



{Continued from page 45.) 



LlMNAEA. 



TX this genus I give simply a list of names, with 

 a few data as to synonyms and localities. 

 Many of the names, doubtless, are synonyms ; 

 some probably represent distinct species. 

 Limnaea peregra, Miiller. 



(j) Subsp. lagotis, Schr., 1803. This, as generally 

 understood, seems to belong with peregra, 

 but I believe various peregra-Yike forms of 

 L. auricularia (as acuta, Jeffr.) are confused 

 with it, and may be included among the 

 varieties cited. Kobelt places our burnetii 

 and lacustris under lagotis. 

 v. acutalis, Morelet. Portugal. 

 v. alata, Sporleder, in Kobelt. 

 v vrnneriana, Hazay. 



v. trmcalconis. Gass., syn. amplaeformis, Kobelt. 

 v. attica. Roth. Greece, 

 v. margaritacta , West. Sweden. 

 v. janovitnsis, Krol. 

 v. confinii, Mouss. Armenia. 

 v. andtrsoni, Cless. 

 v. auricula. West. 

 v.patula, West. Siberia, 

 v sandrii, Kob. 

 v. bi/ormis, Kob. 

 v. lagotopsis, Loc. Syria. 

 v. anticchiana, Loc. Syria. 

 v. subfersica, Loc. Syria. 

 v. ntUyana, Serv. Germany, 

 v. tandriformis, Serv. France, 

 v. iolidior. Mart 

 v. lolidiaima. Kob. 

 Kobelt includes under lagotis the subsp. mucronata. 

 Held, with vars. rubella, alpestris, baderseensis and 

 bartolomata. all of Clessin, and doubtfully v. virens, 



KMT. 



(b) Subsp ovata, iJrap This is hardly a natural 



subspecies, but rather a mixture of lacustrine 



varieties of peregra. 

 v. inflata, Kob. Also said to occur in England 

 v. fmtwaltt. Stud. Also British. 



I maj r. Wot. Hungary. 



f minor. West, France 

 v duMini, Kob 

 v tin.i-.tr. mi. Wes

 I fnuWi, n.-i/ 



- ztkyami, West. 

 v fiumtntnsis, Clcs*. Utea, M<: Taylor 



I .r in Lam. Also Uritish. 



Also British. 



f. pyramidalis, Baud, 

 f. amygdalina, Baud, 

 f. albinos, Baud, 

 f. subscalaris, Baud, 

 f. minor, Loc. 

 f. acuta, Loc. 

 f. inflata, Loc. 

 v. boissii, Dup. Also British. 

 v. tripolitana. Let., in Loc. 

 v. patula. Da C. 



f. ampullacea, Rossm. 

 f. major, West. 

 f. microcephala, Kob. 

 f. hemisphaerica, Mke. 

 f. subrotunda, Borch. 

 f. doliolum, Kob. 



f. glacialis, Dup. Pyrenees, 1 ioc-2600 m. 

 v. obtusa, Kob. 

 v. nouletiana, Gass. 

 v. tencra, Parr., in Kstr. 

 v. lacustrina, Cless. 

 v. physclla, Serv. 



v. balthica, L. If this is really the Linnean 

 shell, and belongs with ovata, it has 

 priority over Draparnaud's name. It is 

 supposed to be the lineata, Bean, of Forbes 

 and Hanley, and limosa of author's. 

 Brown's lacustris has been referred to it, 

 but, according to Taylor, in error. 

 v. succinca, Nilss. 



v. nigrita, Gass. MS., West. Encrusted speci- 

 mens ! 

 v. stccustrupi, Cless. Iceland, 

 v. goilctiana, Cless. Switzerland, 

 v. hazayana, Cless. Hungary. Taylor thinks 



this is boissii. 

 v. Iiasta, Cless. Taylor says this is succincac- 



fortnis, Shuttl. 

 v. btsnardiana, Serv. Germany, 

 v. mamillata, Bgt. MS., Serv. Basses-Pyrenees. 



A form near glacialis.

 v. /aseiata. Kob. Germany, 

 v. acronica, Stud,
