pacifica shows it to be flat dorso-ventrally with a distinct slope 

 downward from the edge of the ooeciostonie. In C. maxima, the 

 ovicell in side view is seen to be ventricose, its dorso-ventral axis 

 being much greater than that of C. pacifica, while the top of the 

 ovieell is flattened. 



This species has been obtained between tide marks at Escondido, 

 Deadmans Island, and Whites Point, California; also dredged off shore 

 from San Pedro to Coronado in depths ranging from 4 to 30 fathoms. 



91. Crisia pugeti sp. nov. 



PI. 20, figs. 20, 21. 



Zoaria composed of stiff, straggling, brittle tufts attached 

 by jointed rootlets. Internodes long, consisting of eleven zocecia, 

 more or less, in the lower part of the colonies, and quickly 

 increasing to 15, 17, and 39, or more, in the upper part of the 

 branches of a colony ; the shorter internodes bearing two or three 

 branches; longer ones often having four branches arranged alter- 

 nately; the first or lowest branch of an internode arising most 

 commonly from the third or ninth zooecium, but sometimes from 

 the fifth or seventh. Joints inconspicuous, light colored, or 

 brown. Basis rami (pi. 20, fig. 20 ba. r.) sometimes wedged in, 

 sometimes not. Zocecia long, slender, often connate throughout 

 their whole length, more usually free at the distal extremity and 

 bent forward. Occcia (oc.) numerous, very long and slender, 

 varying in length between rather wide limits, depending appar- 

 ently on the place occupied by the ocecium in the internode; if 

 high in the internode, then, as a rule, the ooecium is longer than 

 if low in the internode ; adnate throughout the whole length, the 

 main axis in a line with the branch (br 3 .) always given off at its 

 distal extremity; often the third member of the internode, but 

 sometimes the fifth, seventh, ninth, or eleventh. Ocecial internode 

 possessing three or four branches; depending on the place 

 occupied by the ooecium ; if the ocecium is the third member of 

 the internode (fig. 20) then no branch develops below it and the 

 internode will possess but three branches; if it is high in the 

 internode. then there may be four branches, three sustaining the 

 same relation to the ocecium as that represented in fig. 18.
