Terrestrial Amphipods — Hurley 
155 
The gill of peraeopod 4 in the New Zealand 
specimens, in Chilton’s specimens which I 
have referred to T. sylvaticus , and in Hunt’s 
specimens is long, goosenecked and cleft at 
the tip. In Sayce’s it appears to be the same. 
In Shoemaker’s and Stephensen’s it is blunter 
and much more bulbous terminally. 
I have illustrated for comparison the max- 
illipeds and inter-ramal spines of T. sylvaticus 
Haswell (Fig. 2 e-g, k) ; T. kershawi Sayce from 
Mt. Wellington, Tasmania [Chilton Collec- 
tion Tray 152/1-5 (Hi-H 5 )j, (Fig. 4); and 
T. pari ficus from Norfolk Island (Fig. 3). 
It is my opinion that the specimens de- 
scribed by Haswell as T. sylvaticus are identical 
with those later described by Sayce (1909), 
Chilton (1916), Hale (1929), and Ruffo (1948) 
as T. sylvaticus; with those described by Hunt 
(1925) and Rawlinson (1937) as Talitrus dor- 
rieni; and with those described by Schellen- 
berg (1934) and Reid (1947) as Talitroides 
dorrieni. The specimens described by Stephen- 
sen (1935) and Shoemaker (1936) under the 
name Talitrus sylvaticus belong to a different 
species which is here described as new, pro 
forma.

[non] Talitrus sylvaticus Haswell. Stephensen, 
1935: 19-24, figs. 1-3. Shoemaker, 1936: 
60-64, figs. 1-2. 
Maxilliped outer plate distally rounded, 
with oblique row of several setae, across plate 
distally and set in a little from inner distal 
margin. Palp has distal lobe set off by row of 
4 or 5 spinules but not separated from third 
segment. Uropod 1 has large inter-ramal spine 
with terminal spur, a small needlelike acces- 
sory blade at base of spur. Uropod 3 has 3 
large spines on peduncle. Gill of fourth per- 
aeopod terminally blunt and bulbous. Pleo- 
pods 1 and 2 normal, rami well developed 
with real or apparent segmentation, segments 
bearing plumose setae. Pleopod 3 has pedun- 
cle somewhat reduced, with a single vestigial

ramus consisting of short rounded knob, with 
or without single terminal seta. Otherwise 
similar to Talitrus sylvaticus Haswell. 
types: Slides 11-15 (N1-N5), Tray 56, Chil- 
ton Collection, from Norfolk Island; depos- 
ited at Canterbury University College. 
localities: Norfolk Island; Fingal’s Bay, 
New South Wales, Australia (Slides 11-14 
[F1-F4], Tray 127, Chilton Collection). 
DISTRIBUTION: Norfolk Island; Australia; 
Marquesas Islands (Stephensen, 1935); United 
States of America (Shoemaker, 1936). 
remarks: Fuller descriptions and figures 
of this species will be found in the cited 
papers by Stephensen (1935) and Shoemaker 
(1936). Since I have not seen their material 
and they do not catalogue it, I have had to 
nominate as type a series of slides in the 
Chilton Collection. 
SUMMARY 
The generic status of Talitrus is discussed. 
It is considered that Talitroides deserves sub-
