we give illustrations. In a fifth British specie?, Eurydice 

 Grimaldii, Dollfus=/. elegantula, Hansen, the telson has a 

 broadly truncate extremity, which is straight, minutely 

 serrated, and furnished with plumose setae, while each angle 

 is produced to a single spine-point which is larger than the 

 serrations.

Telson with the extremity truncate and serrulated, having 

 at the angles two larger sized serrations (not spines) of which 

 the outer is smaller than the inner ; the central portion o 

 the truncation with a lew setae (about eight) situated in the 

 hollows of the serrulations ; the sides of the telson towards 

 the extremity are also very minutely serrulated. 



Dr. Gough, of the Biological Laboratory, Plymouth, sent 

 to A. M. N., in 1904, specimens of this species taken off 

 Prawle Point, Devon.

Telson contracted toward the truncated extremity, which

is less than half the greatest breadth ; at each angle of the

 markedly the larger ; the central portion between the inner-
