proportionally than in many allied species. Pedicels with two or three annulations just below 

 the hydrothecsB and a number a,t basal end. There are also usually one or two distinct groups 

 of annulations on the median portions of the pedicels. Hydrothecse deeply campanulate with 

 straight lateral outlines, widening gradually from basal part to margin and nearly twice as long 

 as broad. ^ There are 12 well marked, sharply pointed marginal teeth. The diaphragm is well 

 marked and there is a proportionally large and deep basal chamber between the hydranth and 

 the stem proper. 



Gonosome . — Unknown . 



Until the gonosome is found the present writer agrees with Doctor Torrey in assigning a 

 specific name to this form although it may prove a synonym when the gonangia are known. 



Distribution. — La JoUa, California, growing on alga.

Trophosome.' — Colony consisting of a creeping rootstock which is smooth. Pedicels un- 

 branched, long, slender, twisted at base, with two or three spherical annulations near the distal 

 end and with the median portion smooth. Hydrothecse deep, large, with parallel sides longitudi- 

 nally lined, the hnes running downward from between the marginal teeth, teeth large, square- 

 topped, about 12 in number. 



1 Doctor Torrey in his description states that the hydrothecse are less than half as broad as long, but his figure 

 measures more than half as broad as long. 



^ There being no good specimen of this species at hand, the writer takes the following description from that of 

 Hincks (British Hydroid Zoophytes, 1868, p. 162), adapting it iu form to the other specific descriptions in the present 

 work.
