ing from the vestibular spiral out to the tip of the left 

 arm, thence back to the dorsal curve, out to tip of right 

 arm, and then along some distance dorsal to the ventral 

 edge of the right arm, to end abruptly at entrance to 

 funnel. 



2. Another specimen seen from above has 250 length 

 of tube and sac combined (100 tube, 150 sac), width of 

 sac 75 fi, width of tube 40 width of flared lips 75 m. 

 The macronucleus is 20 by 15 and the oral lobes the 

 same size as in preceding specimen; length of animal 

 250 /t, greatest width about 60 since it was but partly 

 contracted. 



3. A third empty case has sac 125 along shorter dor- 

 sal side and tube 125 long. Depth of sac 65 and tube 

 width 37, width of flaring lips 50 The axis of the tube 

 rises about 135 degrees away from the axis of sac. 



4. Another empty sac has the same length, but depth 

 of only 40 fi, and the tube was but just begun or else 

 broken otf, with diameter of about 35 /x. 



5. Another specimen has sac 150 long with great width 

 of 80 /X, short tube 88 long and 40 wich- witli lips (i7; it 

 was seated in the branching aii.uie of the hydroid and 

 faced toward base of hydroid. 



The contained animal was imicli cont i nctcd into sac, 

 150 by 60, with nucleus eloii-atcd 15 by lM, with lobes 37 

 by 14 fi, and the left lobe trnuiiiat.Hl in a paiiilla i'^, by 

 10 ix, recalling the Freia ,^li/lifi'r of Wright that was 

 stated by Ryder to be probably but a variety and which 

 represents a temporary state as, we see it in Folliculinas 

 in the Chesapeake Bay. 



6. The sixth specimen measured: sac 125 by 80, tube 

 150 by 40 with lips 55; inhabited by animal remai-kably 

 well expanded, having main body 16() by 4i) with nm-U'US 

 17 by 22 and lobes stretched out to 1)2 /- and b Mo 12 wide. 

 This animal contained a large diatom as food, while some 

 of the other> contaimMl masses .)f detritus ns if bacteria 

 in digestion. Within the sac next the animal are several 

 nucleated masses, either foreign protozoa or possibly
