AGLAOPHENIA URENS Kirchenpauer 



Aglaophenia urens Kirchenpauer, Ueber die Hydroidenfamilie Plumulari- 

 dae, 1872, p. 46, pi. 1, fig. 27. 



The specimens secured by the Albatross on her Philippine cruise 

 agree quite closely with the description and figures given by Kirchen- 

 pauer, and I have no doubt regarding the identity of the form. 



Locality. — Dredging station 5157. Sulu Archipelago, Tawi Tawi 

 group, Tinakta Island, 5° 12' 30" N.. 119° 55' 50" E.; depth, 18 

 fathoms.

 Port Stephens and Port Denison (Haswell, according to Bale). This

AGLAOPHENIA D1VARICATA (Busk) 



Plumularia divaricata Busk, Voyage of Rattlesnake, 1852, vol. 1, p. 398. 



Aglaophenia ramosa Kirchenpauer (not Busk). Ueber die Hydroiden- 

 familie Plumularidae, 1872, p. 38, pis. 1 and 2, fig. 17. 



Aglaophenia divaricata Bale, Australian Hydroid Zoophytes, 1884, p. 162, 

 pi. 15, figs. 7 and 8. 



(?) Aglaophenia mccoyi Bale, Journ. Microscop. Soc. Victoria, 18S1, p. 24. 



The specimens before me agree very closely with the descriptions 

 and figures of this species given by Bale. In habit of growth, how- 

 ever, there is very wide divergence, our specimens consisting of a 

 number of slender, unbranched, upright stems, all apparently grow- 

 ing from a common creeping root stalk. In the absence of the gono- 

 some, the present writer does not feel justified in separating this form 

 under a new name. 



Locality. — Dredging station 5248, Gulf of Davao, Lanang Point, 

 7° V 25" N., 125° 40' 24" E. ; depth. 18 fathoms.
