438 REPORT OF COMMISSIONER OF FISH AND FISHERIES. [732] 



tal end with the thicker and shorter polypiferous segment, and bearing 

 one or two nematophores on the median line, wbich may be either near 

 the middle or toward the proximal end. Hydrothecse broad, sab- 

 cylindrical, a little longer than broad, with a slightly flaring, even rim ; 

 the axis forms an angle of about 45 with the branches; the free 

 part of the distal side is about half the length of the proximal side. Ne- 

 matophores relatively large, usually three with each hydrotheca : one on 

 each side, shorter than the hydrotheca, trumpet-shaped, with a round, 

 cup-like opening, narrowed below, nearly sessile; another, similar in 

 form, placed toward the proximal end of the segment, inclined forward, 

 and nearly reaching the base of the hydrotheca. Gonothecse not ob- 

 served. 



Off Gay Hea'd, 8 to 10 fathoms, among ascidians; Vineyard Sound, 

 8 fathoms. 



This species is related to P. Catharince Johnston and P cornucopia 

 Hincks, from the English coast. The former differs in having opposite 

 branches, smaller and more elongated uematophores, etc. ; the latter 

 agrees in having alternate branches, but the nematophores are smaller, 

 longer, and more slender, and the joints of the branches are different. 



This is the first genuine species of Plumularia that has been discov- 

 ered on the New England coast.
