200 COLLECTIONS FROM MELANESIA.
In the second collection are two males and a female from Thursday
Island, 3 -4 fms. (No. 175), and a small female obtained on the beach
at Port Darwin (No. 176).
Nearly all of these specimens present the rostral characters
attributed by Haswell to his L. spinifer, but in one example of the
series the lateral teeth of the rostrum are absent. Traces of them,
as very obscure tubercles, exist in the typical examples of L. longispinus
in the Eritish-AIuseum collection.
In some of the specimens the spines of the cardiac and branchial
regions and of the posterior and postero-lateral margins are much
more strongly developed than in others. Besides the above mentioned
Australian localities, Mr. Haswell records this species from
Darnley Island, and Cape Crenville.
23. Lamhrus lævicarpus, Aliers.
Two small males are in Dr. Coppinger’s second collection, obtained
in the Arafura Sea off the N.W. coast of Australia at a depth of
32-36 fms. (No. 160). They agree in all particulars with the
typical specimen, without definite locality, in the Museum collection.
24. Lamhrus longimanus (Linn.).
To this species as I have defined it (‘Annals’, xix. p. 21, 1879)
are to he referred an adult male specimen from Blinders, Clairmont,
obtained at a depth of 11 fms. (No. 108) ; a male and a female from
Port Alolle, 14 fms. (No. 93) ; and a female of large size, with ova,
from Fitzroy Island, 10 fms. (No. 113).
This species, as I have already noted, ranges from the Alauritius
through the Indian and Malaysian seas to the North-eastern
coast of Australia.
25. Lamhrus nodosus {Jacquinot and Lucas).
A small male in the first collection from Port Denison, 4 fms.
(No. 122), belongs here. Specimens from the same locality are
recorded by Mr. Haswell, the original types being from New Zealand.
In the second collection are a male and a female from Thursday
Island, 3 -4 fms. (Nos. 175-177).
Small specimens of this species have a considerable resemblance
to the L. intermedius, described by myself from the Corean seas*,
where also are perhaps to be referred small specimens from
Shark Bay, AV. Australia (Rayner, H.Al.S. ‘H e ra ld ’), in the British-
Museum collection, from which L. nodosus is distinguished hj’ the
prominent and globosely-rounded tubercles of the chelipedes. In
L. intermedius the marginal tubercles of the chelipedes are flattened
and (in the typical specimen) tho palms are quite smooth on
their upper surfaces. Very small granules exist, however, on the
* Proc. Zool. Soc. p. 30 (1879).

upper face of the palms in one (the largest) of the Shark-Bay
specimens.
As there are in the British-Aluseum collection adult examples
undoubtedly referable to L . nodosus from Shark Bay, collected by
Lieut. Suckling, 11.N., and presented by W. Wykeham Perry, Esq.,
it is possible th at L. intermedius may represent merely a young
condition of this species.
26. Lamhrus turriger, White.
An adult male and female, in somewhat imperfect condition, are
in the second collection, from the Arafura Sea, 32-36 fms. (No. 160).
These specimens aro certainly identical with specimens from the
Philippine Islands (Cuming) and Borneo (Admiralty), designated
L. turriger by AVhite, although in thé adult male received from
Dr. Coppinger the spines of the carapace are considerably longer
than in the largest of these examples.
Mr. Haswell mentions the occurrenceof L. turriger at Darnley Island.
As the description and figure of Adams and AA’hite* give an
inadequate idea of this very remarkable form, I subjoin the following
description of the principal specific characters, based upon an examination
of Dr. Coppinger’s adult male :—
The carapace is somewhat rhomboidal, constricted behind the
orbits ; the front prominent, triangulate, acute and deflexed, with a
small tooth or tubercle on each side near the base. The carapace
is armed with long spines, whereof one is situate on the gastric, one
(very long) on the cardiac, and one (very long) on each branchial
region; these spines.are vertical; there is besides a shorter spine
behind and in front of each of the branchial spines, and two, directed
obliquely backwards, on the posterior margin of the carapace. The
chelipedes are very long, more than 4 | times as long as the carapace,
slender, and approaching more nearly to a cylindrical form th an in any
other species I have examined ; the palm is scarcely more dilated
than the wrist; and both arm, wrist, and palm are closely tuberculated
both on their upper and under surfaces ; the anterior and posterior
margins are armed with longer tubercles or short spines, nearly as
in the figure of Adams and White. In the smaller examples some
of the shorter spines of the carapace may not he always developed,
but the four long vertical spines of the gastric, cardiac, and branchial
regions and the two spines of the posterior margin are always
distinct.
27. Lamhrus hoplonotus, var. granulosus, Aliers.
Three specimens from Elinders, Clairmont, N.E. Australia, 11 fms.
(No. 108, first collection), and one from Port Darwin, 12 fms.
Qecond collection), agree more nearly with this variety than with any
other of this protean species, but exhibit a marked approach to var.
longioculis in the subspiniform tubercles of the gastric, cardiac, and
