A BATTLEDORE FRONT 7\ 
and belonging to the British fauna as well as the Neapoli- 
tan in which it first was named. Another Mediterranean 
species, Portunus longipes, Risso, which is also found on 
British coasts, and which is figured and described by Bell 
in the ‘ British Stalk-eyed Crustacea,’ p. 361, is now called 
DBathynectes longipes. 
Family 4.—Podophthalmide. 
The carapace is widest anteriorly, with the ‘front’ 
very narrow, spatuliform, and inflexed. The orbits are 
extremely large, and the eye-stalks greatly elongated, occu- 
pying nearly the whole width of the carapace. 
Podophthalmus, Lamarck, 1801, contains but one 
recent species, the widely distributed Indo-Pacific Podoph- 
thalmus vigil, Fabricius. The long eye-stalks almost 
meet at their bases, and consequently the ‘front’ is there 
almost linear, but it is prolonged for a short distance below 
and transversely dilated, so that, if straightened out, it 
might be compared to a battledore, or a broad-bladed 
knife, a spatula, whence the expression spatuliform has 
been applied to it. The great breadth of the short cara- 
pace, the very large denticulate chelipeds, and the unusual 
though not unparalleled length of the eye-stalks, make 
this a conspicuous and attractive species. According to 
Miers (1886) the only other genus that can claim a place 
in this family is Huphiylax, Stimpson, 1860, the name of 
which, meaning a good watchman, corresponds with the 
family character. 
Legion 2.—Oyelinea. 
The carapace is more or less orbiculate. 
Acanthocyclus, Milne-Edwards and Lucas, 1843, has 
for its type species Acanthocyclus Gay, which occurs com- 
monly on the shores of Chili and Patagonia, and in the 
Straits of Magellan. In this the eye-peduncles are short ; 
no longitudinal ridges are developed upon the endostome ; 
the ‘front’ is rather narrow, with a prominent median 
lobe; in the third maxillipeds the third joint is much longer 
than the small fourth one; the pleon of the male is narrow
