Canon A. M. Xorinan on Oreenland'K- I'uli/zoa. 9,] 



It shows that at that tiino sixty-throo spccii-s were known in 

 the GreeiihiMil sea. Anion;^ the sjjccie.s then known were tiie 

 f'ollowinj^ twenty-six forms* whieh were nut procureil Uy the 

 * Valorous/ atul these, when ailded to my own list, raise the 

 number ol Greenlandio Polyzoa to one hundred and tour 

 forms, now re^^arded as distinet speeies. A tew of the names, 

 Ijowever, may be rejjarded with some doul)t. 



The list of Dr. Liitken is taken ehiefly, though not 

 entirely, from Smitt, " liryozoa marina in rej^ionibus arctieis 

 et borealibus viventia" (CEiVers. Kong. Vet. -Akad. Forhand. 

 (1867) 1868, pp. -il.J— 187). A comparison with this paper 

 of Sraitt enables me to add explanatory notes after the names 

 of some of the species. Species given by Liitken which are 

 not in the following list are contained, altliougli perhaps under 

 a diti'erent name, in the preceding catalogue of ' Valorous' 

 Polyzoa.
