Lafoea re^ia, new species 

 Plate 26, Fig. 13 



Trophosome. — (Description from a fragment 4 cm in length.) Col- 

 ony stout, rigid ; main stem fascicled, but with fewer tubes than in the 

 common species of this genus. In the specimen described as well as in a 

 specimen from Station 1188-40, 6 miles SE of Santa Catalina Island, all 

 of the branches are given off from the same side of the stem, nearly at 

 right angles to the stem; they are fascicled nearly to the end, but the 

 tubes are few. Each of the two largest branches has a secondary branch. 

 The hydrothecae are similar in shape to those in L. fruticosa Sars, but 

 are much larger, 1.8 x 0.4 mm, with one twist at the base; they are 

 given off in regular alternation, fronto-laterally, from the theca-bearing 

 tube, hence they are not nearly in the same plane. The margin flares 

 slightly, and duplication may take place. 



Gonosome. — Not observed. 



Distribution. — Station 983-39, 15^ miles WNW of Santa Barbara 

 Island, 70 fathoms; 6 miles SE of Santa Catalina Island, 150-155 fath- 

 oms; 2^ miles SE of Seal Rocks, 87-90 fathoms. 



Remarks. — The queen of American species of Lafoea bears much re- 

 semblance to L. fruticosa Sars, and particularly to those specimens of 

 that species in which the branches are all on the one side of the stem. 

 The stem may be just as stout as the stem in that species, but there are not 

 so many tubes in the fascicle. The hydrothecae are fronto-laterally, not 

 directly laterally placed, and, of course, they are much larger; there is 

 less twisting in the pedicels. Without any information as to the nature of
