138 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL.4 



Gonosome. — (Only female generative zooids observed.) The gener- 

 ative zooids are much smaller than the nutritive and are devoid of ten- 

 tacles. The sporosacs form a whorl about half way to the base of the 

 tentacles; each sporosac with four large ova. In several cases, a second 

 whorl seems to be developing just distal to the main whorl. 



Other zooids. — No other types of zooids were observed. 



Spines. — The spines are numerous, large (some of them nearly 1.0 

 mm. high), and conspicuous; slightly tapering to a blunt point, with 

 4-6 prominent, rugose ridges, running longitudinally.

Trophosome. — Zooids may grow up singly, or colonies may appear, 

 consisting of a stem and one to several branches. When branches are 

 present they are never regularly or closely arranged, hence the colony 

 is somewhat straggly. The branches and the pedicels bend abruptly near 

 the origin, turning to form an acute angle with the stem, or even run- 

 ning almost parallel with it. The stem, branches, and pedicels are all 

 slender; they are annulated for some distance at both extremities and 

 some of the terminal pedicels are annulated throughout or nearly so. 

 Plydrotheca rather broadly campanulate, with 9-10 distinct, sharp teeth. 



Gonosome. — Gonangia of great length, approximately two and one- 

 half times the length of the hydrothecae, growing from the stolon, from 

 the main stem, or from the branches, with rather long pedicels, annu- 

 lated throughout; elongate elliptical, narrowed slightly just below the 

 margin; surface with slightly wavy lines running from base to margin, 

 or there may be wavy, longitudinal corrugations.

Trophosome. — Minute colonies consisting of one, two, three, or 

 four zooids, growing from a stoloniferous network, over the surface of 

 seaweed. If there are more than one zooid in the colony, the second grows 

 out from the pedicel of the first, slightly below the base of the hydro- 

 theca; the pedicel of the second one curves in the proximal portion so 

 that it continues almost in line with the first; if there is a third zooid, 

 it springs from the second as the second from the first, and a fourth 

 may develop likewise. When there are four zooids in the colony, it may
