32 HYDROIDS COLLECTED BY THE " HUXLEY " FROM 



was taken at Station II., 75 fathoms, and some large branches at 

 Station III. At Station IX., 240 fathoms, a few fragments were 

 secured. 



Broch (1903) records this species at 250 fathoms in lat. 62° 59' K, 

 long. 10° 37' W. 



Hydrallmania falcata (Linn.). 



A few fragments were obtained at Station I., 75 fathoms. 



PLUMULARID^. 



Plumularia elegant ula, G. 0. Sars. 



Flumularia clegantula, G. 0. Sars, 1873, p. 103, Tab. III. figs. 9-14; 

 Bonnevie, 1898, p. 15 ; Bonnevie, 1899, p. 90. 



This species occurred at Station YIL, over 444 fathoms, and at 

 Station XIII., 412 fathoms. At the first station only two plumes 

 were taken. The largest measures 35 mm. in length, and has a few 

 empty gonangia on the stem. At the second station several young 

 colonies were found attached to the coral Lopholielia. 



It is very likely that tliis species is a deep-water variety of Flumti- 

 laria pinnata. It agrees with the latter species in every detail, except 

 that the internodes of the hydrocladia are nearly twice as long. The 

 hydrothecse are smaller in size, and are situated at the distal end 

 of the internodes. Their position is probably due to the lengthening 

 of the internode at its proximal end. It is the length of the inter- 

 nodes that gives the hydrocladia a more delicate and more slender 

 appearance than that seen in the littoral Plumularia fnnnata. 



Distribution. Norway, Kristiania to Bodo, 55-200 fathoms (Bonne- 

 vie, 1899). 



Plumularia setacea (Ellis). 



At Station I., 75 fathoms, very small colonies bearing gonangia were 

 found on Aglaophcnia and Antcnnularia. 



At Station XIII., 412 fathoms, several little colonies witli gonangia 

 were attached to Plumularia frutescens. 



Distribution. Some recent foreign records : — Norway, 55-110 

 fathoms (Bonnevie); Azores, 174 fathoms (Pictet et Bedot); Florida 

 (Nutting) ; California (Nutting) ; Puget Sound (Torrey) ; Chile 

 (Hartlaub); Ceylon (Thornely); New Zealand (Hartlaub, 1901); Japan 

 (Jfiderholm, 1896). 



Plumularia frutescens (Ellis and Solander). 



A few short branches bearing gonophores were taken at Station XIII., 

 412 fathoms. 



Bonnevie records this species for the coast of Norway, 20-160 

 fathoms.
