Rev. T. Hincks on Arctic Hydroida and Polyzoa. 67 



papers was obtained ojf Fredertckshaab, Davis Straits^ in 100 

 fathoms, and amongst bergs grounded and drifting, as stated 

 on the label. How the name Reykjavik came to find its way 

 into the place which should have been occupied by the name 

 Frederickshaab it is impossible to say with certainty. As in 

 other cases Dr. Wallich appears to have written on his labels 

 the date, with the depth and other particulars, but without the 

 name of the place, it is possible he may have done so in the 

 present instance, and that when the bottle was made over 

 to Mr. Busk the wrong name may have been inserted 

 by mistake. However this may be, there can be no doubt, 

 I think, that the Hydroida and Polyzoa which I have 

 catalogued and described are Greenlandic and not Icelandic. 

 All the evidence points in this direction. The date on the 

 bottle containing them iS that of Dr. Wallich^ s visit to Fre- 

 derickshaab^ where he dredged once amongst icebergs^ in 100 

 fathoms. The label exactly resembles one that was attached 

 to undoubted Frederickshaab specimens, in all but the name of 

 the place, bearing the same particulars, written in the same 

 fashion, on the sam_e kind of paper, and in partially faded 

 ink. Dr. Wallich's recollection also favours this view. He 

 distinctly remembers that in the single haul off Frederickshaab 

 a large quantity of plant-like Hydroids came up ; and they 

 actually formed the chief element of the contents of the bottle 

 that passed into my hands. 



On the whole there seems to be little room for doubt ; and I 

 must beg those who may refer to my papers for the locality 

 to credit the species recorded in them to Frederickshaab instead 

 of to Reykjavik. 



While dredging in Reykjavik Harbour, Dr. "VVallich took up 

 a small quantity of Hydroida &c. in 15-20 fathoms, which 

 he has been good enough to send me for examination ; and I 

 am thus enabled to publish a short list of undoubted Icelandic 

 species.
