AMPHIPODA AND ISOPODA FROM BARRJNGTON TOPS. 85 



(3) In the maxlllipeds there are also distinctive features, 

 the chief of which is that the outer lobe narrows towards 

 the apex, so that this is distinctly subacute. It is tipped 

 with a few fine setae, and the inner margin bears a few 

 stouter setae somewhat widely separated, (see fig. 3). In 

 T. kershaivi, the outer lobe has the apex * 4 rather broader, 

 distinctly indented, and clothed with two tufts of setae, 

 separated by the indentation." 1 In Parorcliestia sylvicola 

 Dana, the terrestrial land-hopper common throughout New 

 Zealand, the maxillipeds are considerably different, and, 

 in particular, have the outer lobe well rounded and fringed 

 with numerous spinules. 



Talltrus sylvaticus appears to be very common in Tas- 

 mania, and is also found along the coastal and mountainous 

 regions of Victoria and New South Wales. Sayce records 

 that it is very common throughout Victoria at all elevations, 

 and that he has taken it under dead sea-weed just above 

 tide-level at several places along the coast. The other 

 species, T. kershawi, was found by Sayce at a considerable 

 number of localities in Victoria, but has not yet been 

 observed elsewhere. No species of Talltrus has, as yet, 

 been recorded from New Zealand, where the genus appears 

 to be represented by the common and widely distributed 

 land-hopper, Parorcliestia sylvicola Dana. At the Sey- 

 chelles and Madagascar, however, there is a closely allied 

 species, Talitrus alluaudi Chevreux, which appears to be 

 closely related to T. sylvaticus; it has also been recorded 

 from hothouses in Prance, to which it had doubtless been 

 accidentally conveyed from its original habitat. In 1912, Dr. 

 Caiman 2 described another terrestrial species, T. hortulanus 

 from specimens obtained in the gardens of Kew; it appears 

 to be pretty close to the three species already mentioned,
