C. quadratulum (Gay) De Toni; Gay, Monogr. loc. 

 Conj. pi. 1 f. 15; West, Mngr. Ill pi. 72 f. 33—34. In the 

 description by W e s t it is stated (page 121): „sinus nar- 

 rowly linear with a slightly dilated apex". This is not 

 quite in keeping with the excellent figure given by Gay in 

 which the sinus is open as in the Finnish form. (Also the 

 above mentioned figure by West possesses an open sinus, 

 but not pi. 93 f. 4). Compare also Printz, Beitr. Norweg. 

 pi. 3 f. 58—59. Long. 14,5, lat. 10,6, isthm. 3,2//. [N:o 1022].

var. sublobatiforme, nova var. Cellulae medio incisura 

 anguste lineari profunde constrictae. Semicellulae plus rect- 

 angulares angulis non vel vix oblique truncatis, rotundatis. 

 A vertice visum ellipticum medio utrimque eminentia parvula. 

 Long. 15,8, lat. 11,9, crass. 7,2, isthm. 3,9//. [N:o 1021]. 



The general appearance in front view has a strong 

 resemblance to Euastrum siiblobatum Breb. (West, Mngr. 

 II pi. 40 f. 19), but the vertical view is quite different.
