GARVEIA NUTANS. 295 



that I first obtained the hydroid on which the genus Garveia has been founded. Not finding any 

 pubUshed account of it I described it ^ as a new Edimdriinii-Y)ke, hydroid, but though I beUcved 

 it entitled to rank as a distinct genus, I abstained from publishing it as such without further 

 comparison, considering it safer to wait for the result of a critical examination of the various 

 Eudendnim-\\ke hydroids with which I was then engaged. I therefore recorded it simj)ly as a new 

 species, under the name of Eudendrium baccatum, suggesting for it provisionally the name of 

 Coryihamnion^ to be used in the event of its generic distinctness being established. 



Simultaneously with the publication of my description of the new hydroid there appeared a 

 paper by Dr. Strethill Wright,' in which the same animal was described under the new generic 

 name of Garveia. As Dr. Wright's paper, however, purports to be a report of a communication 

 made by him in the previous January to the Royal Physical Society of Edinburgh, I willingly 

 yield to his claim of priority, and allow the name of Garveia to take precedence over that of 

 Corythamnion. 



One of the most remarkable characters of this curious genus is the position of the 

 gonophores, each being borne on the summit of a true branchlet, where it takes the place of the 

 hydranth on an ordinary branchlet. 



The gonophore-bearing branchlets are much smaller than those which bear the hydranths, and 

 at first sight might be mistaken for the mere peduncles of the gonophores. A little examination, 

 however, will show that they are proper branchlets, not only invested by their perisarc like the 

 rest of the hydrophyton, but quite distinct from the peduncle of the gonophore, which they 

 support upon their summit. In the only representative of the genus as yet known, they are 

 dilated at the summit exactly like the hydranth-bearing branchlets, and from this funnel-like 

 dilatation the true peduncle of the gonophore springs.
