There has been great confusion between the species of this 

 genus. Boeck confused the two British species of Hyale, and 

 his figures of the entire animal of his Hyale Nilssoni, and of 

 the second gnathopod of the male, " undoubtedly," as Sars 

 says, represent H. Liibhockiana. 



Delia Valle, Avith Stebbing's and Sars's clear definitions of 

 the two species before him, actually makes the H. Luh- 

 hockiana of Sars a synonym of his H.pontica, Rathke, which 

 he makes =^H. Nilssoni, Rathke, and keeps H. Lubbockiana 

 of Bate and Stebbing as a species distinct from that of Sars ! 

 A glance with even a hand-lens at the propodos of the 

 perEeopods of the true H. Lubbock.'ana is sufficient at once to 

 recognize the species on account of the two remarkable large 

 serrated spines with which it is armed. These spines are 

 shown in Bate and Westwood's figure k, in Stebbing's 

 fig. 2 c, in Sars's fig. 2, p. 7, and are even sufficiently indi- 

 cated in Boeck's small figure of the entire animal of his 

 " H. Prevostii^'' to show that the figure really represents 

 H. Lubbockiana. On the other hand, it is clear that the 

 species described by Delia Valle as U. Lubbockiana cannot
