Natural History of East Finmarh. 125 



thougli not minutely accurate, can apply to no other genus ; 

 and, secondly, because Stimpson's foi-m is well known in the 

 district where he found it and also in the Gulf of St. Law- 

 rence. Pseudoflustra is perhaps hardly a happy name to 

 have given to the genus, but becomes expressive when the 

 specific name solida is added to it. 



The following differences are seen in the specimens in my 

 collection : — 



a. Cashes Ledge, N.E. America, 70 fathoms [Prof. Verrill). 

 — The form described by Hincks in his St. Lawrence paper, 

 p. 150. The growth is in narrow strips, which at the same 

 time are somewhat thicker and more solid-looking than the 

 other varieties. The avicularium is nearly round (see 

 Hincks, fig. 1) ; a slight sinus is more or less evident on the 

 lower margin of the oral opening, but this sinus is not 

 evident on ooscium-bearing zooecia. Length of a frond 

 25 millim., greatest breadth 4 millim. 



b. " Escharella palmata, Sars, Spitsbergen," from F. A. 

 Smitt. — Zooecia narrow and greatly elongated ; avicularium 

 linguiforra (as Sinitt, fig. 43). 



c. Varanger Fiord, 100-150 fathoms. — Frond very thin 

 and broad, 18 millim. long, 13 millim. broad. Zooecia of 

 much larger size than from the other localities, not much 

 produced; avicularia linguiform (as Smitt, fig. 44). 



It was also taken by the Norwegian North-Atlantic Expe- 

 dition off Yardo (Stat. 2()2).
