Hydrocaulus: Numerous branches. Stems diameter about 

 1/30 inch., risingfrom creeping stolon, to 2 inches, oreven more. 

 Stems presenting at intervais more or less distinctly marked an- 

 nulations. 



Coenosarc forming coUar like expansion just below the Hy- 

 drantli: Diameter of body: 1/5 inch., 1-1 — 20 distal tentacles 

 in two closely approximate alternate séries. — 20 Proximal (abo- 

 ral) Tentacles about 2/5 of an inch in length. 



Gonophores in pendulous clusters forming in the maie long 

 simple racemes, which, vvhen mature surpass the proximal ten- 

 tacles in length and the peduncle is hère branched so as to form 

 a sort of panicle or compound raceme. Gonophores destitute of 

 gastro vascular canals with 4 conical tentaculiform tubercles, 

 larger in the femalethaninthemale. Female gonophores somew- 

 hat more globular than the maie, which are of an elongated 

 oval form. Oral tentacles of Actinula not developed at the time 



of its libération « I hâve no doubt of the identity of our 



species with the Corail ina fuhularia laryngi similis 'Ellis » etc. . . . 

 « I believe also, that the T. coronata of Abildgaard is identical with 

 Ellis' species, notwithstanding the unbranched condition and 



tortuous marking of the steins », etc « while i hâve 



little doubt, that it is the species, which is described by Mr. J. 

 B. Harvey under the name of Tiihidar'm gracilis. » 



<- Hixck's maintains the spécifie distinctness of T. larynx and 

 T. coronata. I cannot see however in the characters contrasted 

 sufficient grounds for distinction. The more important of them 

 appear to me to be merely sexual différences. » 



« When Tuhularia larynx is examined in living state, obscure 

 annular corrugation appear at the stems, in dried spécimens 

 thèse become distinctly marked. I hâve obtained Tuhul. larynx 

 in abundance from the lines of the deep sea, fishing boats, etc. 

 It delights in an admixture of fresh water with the sea (Brack- 

 M'asser). »
