478 PROFESSOR CHARLES CHILTON ON THE 
These specimens resemble those examined by me from Campbell Island, and differ 
from the description of the genus as given by Sreppine in Das Tierreich Amphipoda 
in having the eye present and formed of many facets, though it is pale in colour in the 
smaller specimen. 
The species is widely distributed in Antarctic and sub-Antarctic seas.

South Orkneys, Scotia Bay, Station 825; 9-10 fathoms. April 1903. One 
specimen, 8 mm. long. 
I have been able to compare this specimen with some obtained at South Victoria 
Land by the Nimrod, and with specimens from Plymouth, England, and I agree with 
Mr Wa txer that there is no appreciable difference between them and the European 
species. ‘The South Orkneys specimen has the conical process on the propod at the base 
of the finger a little more obtuse than in the others, but in all other points they agree. 
With regard to L. commensalis Haswell, Mr Sresprne says: “It is perhaps only 
a matter of taste or convenience whether this should be taken as a distinct species or 
as a variety of L. spunicarpa Abildg.” In my South Orkneys specimen the propod 
of the second gnathopod contracts a little more towards the finger hinge than is shown 
in Sars’ figure of the Kuropean form, as it does in the Australian specimens examined 
by Mr Srepsine; on the other hand, the tuberculation of the palm is practically 
intermediate between that shown by Sars and by Haswett, and the resemblance 
throughout is so very close that I see no good object in retaining a different name for 
the Australian specimens. 
Three other species are at present included in the list of Australian Crustacea, viz. 
L. brevidigitata Miers, L. diemenensis Haswell, and L. gracilis Haswell; but, as 
STEBBING points out, it is probable that they should all be included in L. spinicarpa, 
though, as yet, I have not been able to examine specimens. I have, however, examined 
the type of L. antarctica Pfeffer from the Hamburg Museum, and find that it also 
belongs to this cosmopolitan species. 
I may take this opportunity of stating that I have recently (1912, p. 129) united 
L. tridens Stebbing, obtained in New Zealand waters by the Challenger, with the
