o 



This variety is more widely distributed and somewhat 

 more abundant than the typical form. It occurs in similar 

 situations, and is frequently found among the luxuriant 

 Myxophyceous growth covering the wet and dripping rock- 

 of 'the mountain ghylls and glens. It differs from the type 

 in the convex apices, the absence of the small undulations 

 from the upper parts of the sides of the semicells, and in tin- 

 open sinus. 



C. holmiense var. integrum is not unlike C. quadratum, hut 

 the semicells are more attenuated upwards, and the apex is 

 dilated and more convex in the centre. should also be 



compared with C. integerrimum Nag. (' G-att. einz. Alg. 3
