ABIETINARIA AMPHORA, new species.

f. Colony aliout 4 inches high, consisting of a single straight stcni pinnately 

 branched. Stein neither sinuous nor llcxuose, proximal unbranched portion deeply but irregu- 

 larly annulated and without hydrothecse; distal branched portion with distant and very irregular 



internodes. and usually with three hydrothecse between adjacent branches; branches not dividing 

 into branchlets. nodes sometimes entirely absent. usually very distant, there often being but one 

 on a branch, besides the basal constriction. Hv drotheca' suboppositc to sulialteriiate. nuich more 

 closely approximated than in .1. <-<it,it,i (which has si similar gouosome); basal portion Mask-shaped. 

 distal one-half free and curved outward and then upward; margin without teeth, often bearing 

 colla])sible tubular membrane: distal end of hvdrotheca' dorso-ventrally compressed; aperture 

 oval,' directed upward and slightly inward: opercidum consisting of a single adcauline Hap. 



CrOnO80me.Gona,ng\& borne on front of stem and sometimes on basal parts of branches, 

 very la rye. slender. with long neck and round terminal aperture. There are four or five strong 

 longitudinal ridges or crests running from base of neck to near the pedicel.

This species closely resembles A. <>/ .r<nnl< ri, but its hydrothecse are not straight, but curved, 

 as is common in the genus. The gonosomes of the two species are entirely different.

Ti'iijiliiixiini, . -Colony attaining a heiglit of about ."> inches. Stem geniciilate excejit on proxi- 

 mal unbranched portion, where it is straight and diviiled into unequal internodes. distill branched 

 portion divided into unequal internodes. the tendency being to have a branch and two hydrothecse 

 on one side and a single hydrotheca on the other side of each internode. Branches alternate, 

 divided into unequal internodes. the tendency being to have a pair of hydrothecse to each inter- 

 node. As a rule the branches do not subdivide into branchlets. Hydrotheca' large, of the 

 iiliii-tinii type, subopposite to alternate, basal part swollen, distal one-third to one-half narrowing 

 and curving to the round, partially everted margin surrounding the aperture which is usually 

 directed upward; in some cases the margin is distinctly everted all the way around, while in others 

 there is no eyersion whatever; operculum adcaulinc. of a single flap. 



(iniuixniiK . (ronangia small, ovate, with short collar and small aperture, curved slightly in 

 upper part; collar marked with short, spine-like vertical internal projections, (ionangia borne 

 on front of stem and upper side of branches.

The specimens that I have seen are from Santa Barbara. California, and Bering Sea. and 

 they all agree well with I >octor (lark's description of \, ,-t uliir'ni iini/iiiim var. r<>lntxf<i. The .1.
