NEW SPECIES OF HYDROIDS — ERASER 83 



Genus LOVENELLA Allman 



LOVENELLA GRANDIS Nutting 



Plate 16, Figure 9. 



LoveneUa grandls Nutting, U. S. Fish Coium. Bull, for 1899, pp. 325-386, figs. 

 1-105, 1901. 



Trophosome. — Stems simple, rather rigid, luibranched, up to 5 cm. 

 in length, divided into regular, long internodes by single nodes. Hy- 

 drothecae arise on short pedicels, with a double annulation from a 

 process a short distance from the distal end of the internode, regularly 

 alternate ; hydrothecae very large, turbinate ; margin with 10-12 sinu- 

 ations from which arise the segments of the operculum. 



Gotiosome. — (Not previously described.) Gonangium long, 1.5-1.6 

 mm., but rather slender, arises from the axil of the pedicel, the basal 

 portion gradually increasing in diameter, but the distal half prac- 

 tically tubular ; pedicel short, with one annulation. Medusa buds were 

 developing on the blastostyle, but they were not far enough adv^anced 

 to show all the characteristics. 



Type.—U.S.^M. No. 43460. Taken by the United States Fisheries 

 steamer Fish Hawk at station 830, near the mouth of the Sakonnet 

 River, R. I., lOy^ fathoms, August 27, 1880. 



Bemarks. — Nutting described this species from a specimen dredged 

 from Newport Harbor, off Castle Hill, a location very near the present 

 one. As far as I am aware, it has not been reported since until now. 

 Nutting's specimen had no gonosome. 



Family HALECIDAE 



Genus HALECIUM Oken 



HALECIUM DUBIUM, new species 



Plate 16, Figure 10a ; Plate 17, Figure 10& 



Trophosome. — Colony slightly bushy, reaching a height of 3 cm.; 

 proximal portion fascicled to a limited extent. Nodes not very 

 strongly marked; internodes long, turning alternately to one side and 

 to the other, making a zigzag main stem. The hydrophore, with rela- 

 tively long pedicel, is given off near the distal end of the internode; 

 this pedicel makes much the same angle with the vertical as the inter- 

 node of the stem does. The hydrophore may give rise to one or more 

 other hydrophores as duplications, the pedicels of these varying much 

 in length; the margin of the hydrophore is slightly flaring. The 

 branches arise in the same way as the liydrophores, so it would appear 

 at first glance that the branching is dichotomous, but the branch is 

 not like the main stem ; the proximal portion is like a hydrophore with
