Hah. Two specimens from Thomas Edward, taken at 

 Banff, Scotland : Mns. Nor. 



Distrih. West (voast of Greenland (Bovallius). 



On referring to Edwards's own notes it is clear that Bate 

 and Westwood Lave erroneously applied the profusion which 

 Edwards saw in Parathemisto oblivia to Vibilia. 



In drawing up the specific characters of C. borealis to distin- 

 guish it from other species, Bovallius writes : — " As the specific 

 character given by Bate and Westwood is applicable to several 

 of the known Vibilice, the diagnosis here is taken from the 

 generic characters of the authors compared with the drawing." 

 The brief diagnosis of the two species is as follows : — 



The head is not rostrate. 



a. The pereional segments are dorsally smooth. 



aa. The fifth and sixth pairs of pereipoda 



are scarcely longer than the third and 



fourth pairs. 



aaa. The femora of the first and second 



pairs of pereiopoda (?'. e. the gnatho- 



pods) are narrow. 



1 . The peduncles of the uropoda are 



shorter than the rami T'. borealis, B. & W. 



2. The peduncles of the uropoda are 



longer than the rami V. Kroyerii, Bov. 



Respecting the uropoda, Bovallius has taken the character 

 of V. horealis from B. & W.'s woodcut, and while he has 

 adopted the generic characters, in certain respects he has 

 taken no notice of the statement " Three posterior pairs of 

 pleopoda with the peduncle long and the rami short and 

 compressed.^' This description of the uropods agrees with 

 my specimens received from Edward, and thus does away 

 with the assumed difference of V. Kroijeri and V. horealis.
