1 The figure which Westwood gives of "Stegocephalus (Kroy.) ampulla (Phipps)" has the postero-Iateral angle of the third pleon-segment 

 acute and a little upturned, but otherwise it closely agrees with Kr0yer's Stegocephalus inflatus. Bell gives "Stegocephalus Ampulla, Kroy.," 

 in the synonymy by mistake for Stegocephalus inflatus. In the definition of Stegocephalus (see p. 19S) Kr0yer says, "Pedes quinti paris pedibus 

 tertii quartique paris structura et directione similes," a peculiarity at which he himself expresses his surprise, Naturh. Tidsskrift, ser. 2, Bd. i. 

 p. 528, but Dana and Boeck are no doubt right in regarding the statement as an error. 



• On p. 391, line 4, and p. 538, line 42, for Christiancnsis read Christianiensis. 



3 The statement that this species is the same as Cancer ampulla, Phipps, has lately been corrected by Hansen, see pp. 599, 729.
