JASSID^E. 93 



The second gnathopod of the female in this species is dis- 

 tinguished by its deeply and evenly concave palm, and by the 

 finger which, extending beyond the palm, closes on the side 

 of the hand in the middle of several short stumpy spines. 

 Two females taken at Falmouth in 1884 (A. M. N.}. 



BRUZELIELLA OCTA (Bate). 



1863. Podocerus ocius, Bate & Westwood, vol. i. p. 450. 



This species is unknown to us. Chevreux gives the 

 following as synonyms : (1) Podocerus denies, Czerniavsky, 

 Materialia ad Zoogr. Pont, comparatum, 1868, p. 100, pi. vi. 

 fig. 35 ; (2) Podocerus ochtx, Nebeski, " Beit. z. Kennt. d. 

 Amphip. der Adria," Arb. Zool. Inst. Wien, vol. iii. 1880, 

 p. 154, pi. xiii. fig. 43 ; and (3) Delia Valle, p. 448, pi. xiv. 

 figs. 11-27. The figures given by Nebeski and Delia Valle 

 show that the specimen figured by Bate and Westwood is a 

 female, though the illustrations of the second gnathopod in the 

 (wo sexes make it clear that the sexual differences in this limb 

 are much less marked than is usually the case in this genus. 

 The fact that B. ocia is known in the most distant parts of 

 the Mediterranean basin, and has only been extremely rarely 

 found on the south and west coasts of Britain, while it is 

 unknown further north, tends to show that it is an essentially 

 southern form. 



The type specimen described by Bate was taken by 

 Mr. Gosse near low-w r ater mark at Ilfracombe.
