Tills variety is reckoned tog-ether witJi oc typica in the tables 

 for the first half of the year 1899. Its place is between that form 

 and r(tr. obtusangula (Ostenf.) Jørg. and C. edentata Er.\ndt, 

 most near the two latter; it is, however, so different from them 

 that it oug-Jit not to be considored rig-ht away the same as mr. 

 ohtu^mifjula. 



The length of the tail tip as usual varies considerably. The 

 relation between length and breadth generally lies between 2.5 

 and 3 (the tail tip excluded). 



Fig. 119 is a smaller, more divergent fonn. 



Numerous and frequent, as a whole, in the present material, 

 the most frequent form of the species. Occurred also, though in 

 small numbers, during the diatom inflow. It is more frequent than 

 appears from the tables, as it was not entered separately from the 

 lirst, but is included under „Cyttaroe!/lis denticulata" .

Distribution: Cleve's D. clegans Ehek. which also includes 

 the two forms mentioned, is widely distributed from the warmer part 

 of the Atlantic to beyond Iceland (Cleve J^. 40, p. 114). Accord- 

 ing to Cleve, also known from the Mediterranean, the Red Sea 

 and the Indian Ocean. Rare on the west coast of Norwav.
