Canon A. M. Norman on Greenlandic Polyzoa.

On the occasion o£ the last British Arctic Expedition of 1875 

 H.M.S. 'Valorous' accompanied tlie * Alert ' and 'Discovery' 

 as far as Disco Island with additional stores, which were 

 there transferred to the exploring ships. The Admiralty, in 

 response to an application from the Royal Society, directed 

 that the ' Valorous ' should subsequently do a little dredging 

 in Davis Strait and on the return voyage across the Atlantic ; 

 and my old friend Dr. Gwyn Jeffreys accompanied the 

 ' Valorous ' in order to act as naturalist and superintend the 

 dredging. After the return of the expedition a short rep>rt 

 of the biological results was made to the Roj'^al Society, in 

 which Dr. Jeffreys reported on the Mollusca, Dr. M'Intosh 

 on the Annelida, and myself on the other classes of the 

 Invertebrata (Proc. Royal Soc. vol. xxv. no. 173, 1876, 

 pp. 170-237). 



At p. 205 of the Report just referred to I stated that 

 sixty-six species of Polyzoa had been determined as having 

 been brought home by the expedition, and certain of the 

 more interesting species were mentioned under the head of 

 tlie several dredgings. No full list was, however, given, and, 

 moreover, there were other forms at that time undetermined. 

 1 have long purposed to give a complete catalogue of the species 

 procured, but have regarded the existing nomenclature as so 

 unsatisfactory that 1 disliked using it. As some continental 

 zoologists, however, are now working at the Arctic Polyzoa, 

 I feel that it may be useful to publish the ' Valorous ' species. 



In my " Notes on the Natural History of East Finmark,'' 

 in dealing with the Polyzoa (Ann. & Mag. Nat. Hist. ser. 7, 

 vol.xi. 1903, pp. 5G7-598, and vol. xii. pp. 87-128), after an 

 attempt to rearrange some earlier genera of the Ciieilostomata, 

 I wrote (p. 108) : — " As I feel tiiat 1 cannot use as though 

 they were my own many associations of generic and specitic 

 names which have been employed, I shall signify my doubts 

 as to the allocation of the species by putting the generic name 

 wiihin inverted commas.'' The same course 1 liere pursue.
