would place it in the family of the Tululariida. To this 

 view I am unable to assent, although it has received a cer- 

 tain measure of support from Prof. All man. The Acaulis 

 is furnished at first with a verticil of filiform tentacles near 

 the base of the polypite (though they are said to disappear 

 subsequently) ; and between these and the upper capitate 

 tentacles the reproductive buds are developed on the body. 

 But Myriothela, so far as we know, is destitute of basal 

 tentacles at all stages of its existence, and the gonophores, 

 instead of being borne on simple or branched pedicels as in 

 the Tubnlariidce, are produced on distinct coryniform zooids 

 small, rudimentary polypites, which are homologous with 

 the (so-called) gonoblastidia of Hydractinia or Dicoryne. 

 It is, as I have said before, a cluster of polypites nearly 

 related to Coryne ; but its marked peculiarities would seem 

 to entitle it to stand as the type of a separate family.

POLYPITE cylindrical, very extensile ; tentacles extremely 

 numerous and closely set, covering about three-fourths 

 of the body, with a reddish-brown spot on the capitulum ; 

 the basal portion of the body minutely speckled with 

 white, and crowded with the processes bearing the 

 gonophores, which are slender, pointed above, with a few 

 minute wart-like tentacles on the upper portion ; GONO- 

 PHORES produced a little below the tentacles, subsessile, 

 globular, when mature of a very large size and a pink
