') Om de grønlandske Arter af Slægten Хгшпаеа siger Mørch i sit kritiske 

 . Arbejde "On the land and fresh-water Mollusca of Greenland^ (Amer. Jour- 

 nal of Conchology vol. 4, 1868, p. 33) Ы. a.: «Beck mentions, in his 

 Index [Moll. Musei Princ. Christian! Frederici] , 1837, for the first 

 time, three species of imncea from Greenland, viz.: No. 11. L. Vahlii, 

 В.; var. a. lœvigata, var. h. inæqualis. 12. L. Fincjelii, В. 13. L. 

 HolbøUi, В.: a. major, h. minor. Some time afterwards one of the 

 varieties was distinguished in MSS. as L. Grænlandica, В., probably 

 the same mentioned in Jay's Catalogue, 1850, p. 269, Nr. 6298. 



Beck communicated these names, probably from memory, to Møller 

 in such manner that the names of the Index and the collection were 

 confounded and perhaps even applied to species unknown to Beck. As 

 Beck has not described his species 1 have, in the following, considered 

 Moller's Index as the starting point, and used his typical collection and 

 manuscripts.» 



At benytte Becks Navn som Autornavn ved nogen af de grønlandske 

 Limnæer synes mig efter Mørchs Udtalelser ganske forkasteligt.
