A FEW CCELENTERATES OF WOODS HOLL.

few tentacles, the medusa-buds in the " usual position," no mor- 

 phological features are given. The habitat and association with 

 the sponge are interesting facts, but without taxonomic significance. 



It is unnecessary to repeat here the characters by which Syn- 

 coryne linvillei is distinguished. A glance at the figure (1) of a 

 portion of a colony, with the reference already cited, will suffice to 

 afford ample opportunity for comparison to those concerned. I 

 may add, however, as was intimated in the original description, that 

 while having generic characters in many points conformable with 

 those of Syncoryne, still there are points of considerable differ- 

 ence. And with McCrady's figures and description before one it 

 is at once apparent that my species belongs to Corynitis and not 

 to Syncoryne, as already intimated. 



A comparison of the several figures of Corynitis and Gemmaria 

 will make more evident the points under consideration. For ex-

ample, a comparison of Figs. 2 and 3 which represent corres- 

 ponding stages in the medusae of Syncoryne linvillei and Cory- 

 nitis agassizii will strongly suggest their close resemblances and 

 probable generic identity, as already indicated. 



Futhermore, a comparison of Fig. 4, representing the free 

 medusa of Corynitis agassizii, taken directly from McCrady's 

 drawing, with Figs. 5, 6 and 7, representing medusse of Gemmaria, 

 will also show one at a glance the unmistakable distinctness of the 

 medusse portrayed. Fig. 5, copied from McCrady, represents
