earlier described L. traillii G. M. Thomson, as the small differences given in the 
descriptions were found not to hold for all specimens or to be based on misconceptions. 
It is not unlikely that this species will also prove to be only a form of L. spinicarpa 
Abildg.

South Orkneys, Scotia Bay, Station 325. Several specimens, all of small size, 
about 3 mm. long. 
These specimens certainly agree with STEBBING’s species described from Marion 
Island, but they are also the same as the species previously described by THomson 
under the name Amphilochus squamosus, from New Zealand. This latter species, which 
has been accidentally omitted from the list in Das Tierreich Amphipoda, is fairly 
common in New Zealand, and I have long noted that it is very closely allied to the 
Challenger species, and the present opportunity of examining specimens from another 
locality that undoubtedly belong to STEBBING’s species confirms this. The New Zealand 
specimens are usually covered with dark, reddish-black spots, and some of the South 
Orkneys specimens still show signs of similar coloration. Mr THomson described a small 
accessory flagellum on the first antenna, and, though this does not appear to have been 
noted by others in this genus, which is deseribed in Das Tierreich as being “‘ without 
accessory flagellum,” it is undoubtedly present also in the South Orkneys specimens. 
Watker has pointed out that A. neapolitanus Della Valle, 1893, is perhaps the same 
as A. marionis; in describing his species Srepsine originally compared it to A. 
tenumanus Boeck. It will probably be found to be either the same as or very closely 
allied to one of the northern species. Mr THomson’s name has priority over all except 
A. manudens Bate and A. tenwimanus Boeck.
