48 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 4 



Distribution. — North of Wenman Island, 100-150 fathoms; James 

 Bay, 50-70 fathoms; Caitago Bay, 32 fathoms; between Charles and 

 Indefatigable islands, 60 fathoms; east of islands off Navidad Head, 

 25-35 fathoms. 



This species appears to be intermediate between L. gracillima and 

 L. fruticosa. The shape of the hydrotheca and its pedicel and the nature 

 of the coppinia mass bear considerable resemblance to L. gracillima, 

 while the mode of branching and the angle that the hydrotheca makes 

 with the branch resemble L. fruticosa. The size of the hydrotheca in 

 L. gracillima varies much but, in general, that of L. intermedia is inter- 

 mediate between that of L. gracillima and L. fruticosa. The hydro- 

 thecal tubes of L. intermedia are quite characteristic, being quite differ- 

 ent from those in either of the two species but particularly so when 

 compared with those of L. fruticosa. 



Genus LIGTORELLA 



Lictorella adhaerens, new species 

 Plate 11, Fig. 54 



Trophosome. — Main stem strongly fascicled, rigid, 50 mm. ; the 

 individual tubes slender. Few hydrothecae and nematophores on the 

 stem. Branches slender as compared with the stem but, like it, rigid; 

 arranged in subopposite pairs, each making almost a right angle with the 

 stem. Some of the branches are fascicled slightly toward the base, but 

 most of them are simple throughout. Hydrothecae with regular alter- 

 nate arrangement, each with a short pedicel not adhering to the branch, 

 although the hydrotheca itself is adherent in its basal portion; hydro- 

 theca regularly curved, so that the margin is parallel to the branch and 

 some distance from it. Alargin commonly reduplicated. A nematophore 

 attached to each pedicel. 



Gonosome. — Not observed. 



Distribution. — Between Charles and Indefatigable islands, 120 

 fathoms.
