Genus CLADOCARPUS 



Trophosome. — Hyrothecse deep with the margin smooth or with 

 low blunt teeth; mesial nematophore short. 



Gonosome. — Gonangia borne on the stem, at the bases of the 

 hydrocladia protected by processes (phylactogonia) springing from 

 the base of the hydrocladia; these have nematophores but no 

 hydrothecae. 



Cladocarpus vancouverensis new species 



PI. XXXV, Fig. 132 



Trophosome. — Stems simple, unbranched in all the specimens 

 obtained, longest specimen 12 cm.; hydrocladia regularly alternate, 

 those on the two sides not in the same plane, divided into regular 

 internodes; hydrothecae much deeper than wide, the two margin with 

 one central, distinct, but not large, sharp tooth, the remainder weakly 

 crenulated. The supracalycine nematophores are long but do not 

 reach beyond the hydrotheca; the mesial nematophore is projected 

 outward, distal portion free, jointed near the base; a septal ridge is 

 present at the base of the supracalycine nematophore, one at the 

 base of the hydrotheca and two others regularly placed between 

 these. 



Gonosome. — Gonangia borne on the front of the stem and pro- 

 tected by phylactogonia, which are two-pronged, but each of these 

 prongs may be two-pronged; they are oval or somewhat ovate with 

 distal end rounded. 



Distribution. — Lasqueti I., West Rocks, Northumberland Channel. 



I believe this is the first record of a species of Cladocarpus from 

 the west coast of North America. Most of the species are tropical but 

 some have been found in the North Atlantic or in the Arctic near by. 

 Almost without exception the specimens have been obtained from 

 deep water and this seems especially true of the forms found in the 

 colder waters. The records read 80 fathoms or over. Ritchie re- 

 cords two species, C. bonnevieœ and C. campanulatus™ but does not 

 give the depth at which they were found. Unless these were in shal- 

 lower water, there have been no northern specimens found at as little
