Egmundella polynema, new species 

 Plate 25, Fig. 8 



Trophosome. — Zooids commonly grow singly, but at times a pedicel 

 grows out from the side of the original pedicel, not far below the base of 

 the hydrotheca, curves immediately so that it continues in much the same 

 direction as the original pedicel ; the pedicel is not as long as the original, 

 but it is long enough to overtop the original hydrotheca. The pedicels of 

 the individuals dififer much in length, the greatest height of a zooid ob- 

 served being 3.6 mm. When the second zooid is present, the colony may 

 reach the height of 4.5 mm. In nearly all cases, the pedicel is slightly 

 annulated, but the position of the annulations varies greatly. The hydro- 

 theca is of the regular, turbinate type, 1.0 x 0.25 mm; there are 12 seg- 

 ments in the operculum ; the diaphragm is well marked. The unique fea- 

 ture of the species is the clustering of the nematophores, usually shortly 

 below the hydrotheca, where there may be as many as a dozen or more, 

 but more commonly fewer. 



Gonosome. — The gonangium grows directly from the stolon; it is 

 definitely cylindrical, about 1.8 mm in height, and 0.25 mm in diameter. 

 It has an operculum divided like that of the hydrotheca, but the tip of 

 the convergence is but little above the rim. Lines run down from each 

 point of separation the full length of the gonangium. There is a constric- 

 tion at the base to give the appearance of a pedicel. The gonangia were 

 empty. 



Distribution. — Station 1253-41, 8 miles west of Cedros Island, 64-6^5 

 fathoms. 



Remarks. — The species is much larger than the only other species 

 reported from the coast, E. gracilis Stechow. It is more nearly the size of 

 E. grandis Fraser, found on the Atlantic coast, but it is not much like it 

 in other respects. The segregation of the nematophores is the unique fea- 

 ture of the species.
