,Nr. 28. Aglaophenia sp. ([naba 1890 Fig. 78, 79, 80, 81.) 



Trophosome. Stern 200 mm high, with many irregulär branches, 

 the stem and the larger branches composed of several tubules, only 

 the terminal branches consisting of a single tubule. The branchlets 

 growing out alternately one from each Joint, all in one plane. 

 Hydrothecae flask-shaped, with a wide middle part and narrower 

 ends, making an angle of about 35" with the axis, with a trans- 

 verse furrow-line in the lower part, mouth open, with wavy borders 

 and with a .sharp tooth on the front edge. There are two trans- 

 verse furrow-lines on each Joint of the branchlets, one continuous with 

 the similar line of the hydrotheca and the other arising from the 

 base of the lateral nematophores. Frout-nematophore tubulär, of nearly 

 the same length as the hydrotheca, the lower half fused with the 

 hydrotheca, the upper half free and projecting far forwards. Lateral 

 nematophores also tubulär and long, curved outwards and upwards. 

 Nematophores of the stem short, strongly built, 2 to each Joint, 

 1 above and 1 below the brauch. 



Gonosome. Gonophore ellipsoidal, the corbula open, the branch- 

 let usually consisting of three joints, with 3 nematophores on
