is generally to be found along with Cymathcre 

 in situations where the surge is weak but is 

 not quite so much restricted to quiet waters as 

 is Cymathere. From this position, close to 

 the emergent zone, it extends out an unknown 

 distance into deep water where wave action is 

 a minimum. That it grows out in very deep 

 water is rather confidently inferred from the 

 circumstances of its appearance at Port Renfrew. 

 The shallow water specimens collected in vari- 

 ous tide-pools and recesses were all compara- 

 tively short and badly eroded away so that 

 even the smallest specimens found were quite 

 imperfect. 



Besides these, others were found in the wash 

 at " Dictyoneuron Cove" which bore a very 

 different character — so different that it seems

 acter given below, may be designated Renjrewia 

 parvida perlonga var. nov. Though truncated 

 by wear at the tips, the plants all maintained a

 often- more than a meter, while the longest
