PLUMULAEIA PALME EI Niitting

Plumularia palmeri Nutting, American Hydroids, Part I, 1900, p. 65. 



Distribution. — San Diego, Cal., Victoria, B. C. (Nutting) ; 

 Ucluelet. 



The gonosome of this species has not been hitherto described. 

 Many of the Ucluelet specimens have gonangia arranged along 

 the greater portion of the length of the stem, while others are 

 less plentifully supplied. These gonangia, as is the case with a 

 good many species of this genus, have their origin by a short 

 pedicel, from the basal process of the hydrocladium. They are 

 irregularly oval in shape, with the distal end usually larger than 

 the proximal. Though in some cases there is a slight narrowing 

 in the nature of a neck at the distal end, this end is usually club- 

 shaped. They are closely applied to the stem for at least a por- 

 tion of their length, and this may account for some of the ir- 

 regularity of shape. They are but little like the gonangia of 

 P. setacea, consequently, the gonosomes show that these two spe- 

 cies are not synonymous, as Torrey says'^ I can not see much 

 resemblance in the trophosomes of the two either. In my mate- 

 rial, P. palmeri bears a much greater resemblance to P. lageni- 

 fera, so much so that there seems to be almost a complete series of 

 intergradations between the two.
