Natural History of East Finmarh. 410 



I dredged this species on two occasions in quite shallow 

 water, in 5-30 fathoms, in the inner part of Lang Fiord. It 

 is new to the Norwegian fauna. The size of one of these 

 specimens is nearly double that represented in Danielssen and 

 Koren's plate, and the single row of spines passing down the 

 centre of the back of each arm is very conspicuous, as in the 

 figure referred to. On the other hand, in much smaller 

 specimens collected in the Kara Sea by the ' Dijmphna ' 

 expedition, for which I am indebted to the Copenhagen 

 Museum, this central row of spines is scarcely noticeable. 

 Tlie character which at once distinguishes A. panopla from 

 A. Linckii consists in the spines on tlie under surface of the 

 arms, where bordering the ambulacra is seen a row of slender 

 spines which are in pairs, and exterior to these another row 

 of well-developed and conspicuous spines (see Dan. & Kor. 

 pi. V. fig. 2, at the base of the left-hand side of the arm). 

 O.lie following quotation from Levinsen well describes the 

 adambulacral papillse and spines, outside of which is the 

 other row of spines to which I have just referred : — " Papillae 

 adambulacrales biseriales appositae, inter papillas singulas 

 seriei interioris jam pcdicellarice, jam spinse, vestigia trans- 

 forraationis in pedicellarias saepe exhibentes, sitae. Spinae 

 extra papillas adamlnilacrales per paria dispositae, spinis 

 singulorum parium ad basin concurrentibus, supra diver- 

 gentibus.^' 



ECHINOIDEA. 



Echinus norvcgicus, Diiben & Koren. Ilather small specimens were 

 taken by the ' Voringen ' off Vardo (Stat. 262). 



escuhntus, Linne. Herr Grieg writes to me that this species 



has recently been taken by Dr. Johan Hjort iu the Varanger 

 Fiord to the south of Kiberg. 



Strongijlocentrotus drbhacldensis, 0. F. Miillei". Varanger, Lang, 

 and Klosterelv Fiords. 



inclus, Norman. Varanger Fiord, 100-125 fathoms ; Klos- 

 terelv and Lang Fiords, in 3-30 fathoms. This form — whether 

 species or variety — is characterized among points already 

 described by the very large size of the " spherides " (Lovex,). 

 Professor Loven showed me the same form under another name 

 in the Stockholm Museum. Unfortunately I did not make a 

 note at the time, and have forgotten what that name was. 



Schizaster fra(jUis, Diiben & Koren. Taken in mid-channel in the 

 Varanger Fiord iu lOU-12.5 fathoms. A. specimen measured 

 75 millim. long, 65 millim. broad, and 40 millim. deep.
