This species was originally described from a fragment in a col- 

 lection from the San Juan Archipelago. Since than nothing has been 

 seen of the species until on this occasion a fine complete colony was 

 obtained as well as some separate fragments. The complete colony 

 looks much like a colony of Lafœa gracillima or at least like certain 

 colonies of that species when the branching has taken place in one 

 plane only. Possibly, if a number of specimens of L. Carolina were 

 obtained there might be the same variety in it as in Lafœa gracillima. 

 The branching has a dichotomous appearance. The main stem, 4 

 or 5 mm. from the base, divides into two nearly equal branches, which 

 separate rather widely from each other. Each of these branches again 

 but the outer branch is the stronger. Each branches again and this 

 is continued to form a fairly compact but widely spread system of 

 branches. The distance from the base to the end of the ultimate 

 branch in the specimen is 35 mm. The fasciculation which is quite 

 extensive in the basal portion becomes less with each branching until 

 before the ultimate branches are reached there is but the single hydro- 

 theca-bearing stem. To the description of this and of the hydro- 

 theca as originally given, there is nothing special to add unless it is 

 that while in the majority of cases the hydrotheca has the curve which 

 has been described, occasionally it is almost as straight as that of 

 Lafœa fruticosa, which it resembles closely. 



Family sertularim: 



Abietinaria abietina (Linnaeus) 



Sertularia abietina Linnaeus, Systema Naturae, 1758, p. 808. 

 Abietinaria abietina Fraser, West Coast Hydroids, 1911, p. 57. 



As has been previously stated, this species made up the chief 

 bulk of the collection. It is of a very robust type and the colonies 

 are large as well. The majority of the species are much overgrown 

 with other hydroids and with bryozoa. No gonangia were present 

 on any of the colonies. 



Abietinaria gracilis Nutting 



Abietinaria gracilis Nutting, American Hydroids, Part II, 1904, p. 120. 

 Abietinaria gracilis Fraser, West Coast Hydroids, p. 61. 



One complete colony in good condition of this rather rare species 

 was obtained.
