470 Mr. A, O. Walker on the Amphipoda 



was overlooked entirely by the author, and subsequently was 

 said by Fr. Muller (Arch, fiir Naturgeschichte, 1848) to be 

 rudimentary and one-jointed, while in Sars's and Bate's species 

 it is long and six-jointed. The form figured by Delia Valle 

 as L. jnlosus (Zacld.) certainly agrees better than Sars's with 

 the original description, as also with L. pectinatus (Norman). 



Protomedeia Whitei (Bate). One specimen. 



Evidently Cheirocratus Sundevalli, female, as suggested 

 by Norman. 



Bathyporeia yilosa (Lindstrom). 



Two tubes so labelled. Of these no. 50 contains two 

 females of B. norvegica (Sars) ; the other (no. 85) contains 

 eleven specimens, all of which have dark eyes ; some have 

 dorsal spines on the fourth pleon-segment, others have not ; 

 one (a large female) had a rudimentary tooth slightly in front 

 of the rounded hind margin of the third pleon-segment. 



Bathyporeia pelagica (Bate) . One adult male, 5 millim. long. 



This agrees with the form described by Sars under the above 

 name. The eye is large and dark, but it is impossible to say 

 what colour it was when fresh, as red eyes sometimes fade 

 entirely in spirit and sometimes turn dark. It must be con- 

 fessed that, of the five species of Bathyporeia given by Sars, 

 only B. norvegica (Sars) seems to be distinct, owing to its 

 having the hinder angle of the third pleon-segment produced 

 to a point, instead of being rounded, as in the other species. 



Gammarella Normanni (B. & W.). Not in the collection. 

 Is O. hrevicaudata (Milne-Edwards), female. 



Melita proxima (Bate) . 



Of this Norman says it " is the common form of the male, 

 and Megamcera Alderi is the female of Melita ohtusata (Mont.). 

 The variety of the male with a central dorsal tooth on the 

 second and third segments of pleon is far less common.''' See 

 also for this and M. gladiosa (Bate) the same author in Ann. 

 & Mag. Nat. Hist., August 1889, p. 133. 



Eurystheus erythrophthalmus (Lilljeborg). 

 Now Gammaropsis erythrophthalmus. 



Eurystheus hispinimanus (Bate). 

 The female of the last species.
