In 18()8 I pointed out that Bate and Westwood's H. oblivia 

 was not that of Kroyer ; and as no other specimen has since 

 been found, I cannot help suspecting that Bate has described 

 and figured the second limb of the first gnathopods as the 

 second gnathopod : if so P. gracilipes may hereafter become a 

 synonym of Krbyer's species. 

 ' Hah. Banff {t. Edward) *. 



* In confirmation that Bate and Westwood's figure is incorrect, it 

 may be noticed that the figure is taken from a specimen sent to the 

 authors by the late Thomas Edward of Banff. Now 1 have specinens of 

 the true P. ohlivia received from him, and in T. Edward's " Stray Notes 

 on some of the smaller Crustaceans," Journ. Proc. Linn. Soc. vol. ix. 1867, 

 pts. 143 and 166, we are told that " H. oblivia " occurs in enormous shoals 

 at times in the Moray Firth, filling the rock-pools " with literally one 

 living mass" and cast up on the shore as "a ridge or wall extending 

 more than one hundred feet in length, and varying from one to two 

 inches in height and bread tli."
