THE GREAT WARTY CRAB 121 
additions to the type species Hurynome aspera (Pennant), 
for though the names scutellata and boletifera have been 
given to forms taken in the Mediterranean, it is probable 
that they are not distinct from, or at most are only 
varieties of, the species found on the British coasts. It is, 
as might be guessed from the names, a species rough with 
warts or tubercles. The walking-legs are short, but the 
chelipeds in the male are elongate, being nearly twice the 
length of the body according to Bell, but according to 
Leach three times its length. Hurynome tenuicornis, 
Malm, from Bohusliin, Guilmarsfjord, 1s there found to- 
gether with Hurynome aspera. 
Partherdpe, Fabricius, 1798, has in its type species, 
Parthenope horrida (Linn.), an animal of truly remarkable 
appearance. It is recorded from the West and Kast Indies, 
and has been called the great Warty Crab or stigmatised 
as the Lazy Crab. Its carapace is pentagonal, broader 
than long. While this and the legs are covered with 
warts and spines, the pleon is said to be full of pits, almost 
as if eaten through. The chelipeds are large and long. 
From the picture of it given by Herbst one might suppose 
that it was intended to look like a piece of light-red sand- 
stone overgrown here and there with green alge. 
Lambrus, Leach, 1815, unlike the two preceding genera, 
suffers from no paucity of species. So numerous indeed 
are they that in 1878 Professor A. Milne-Edwards deemed 
it expedient to subdivide Lambrus into ten genera, in- 
cluding in the number Solenolambrus, Stimpson, and 
Mesorhwea, Stimpson. ‘The. species are distributed over all 
the warmer seas of the world, and some occur in the Medi- 
terranean. Of these Lambrus macrochélos (Herbst), mean- 
ing the Lambrus with long chelipeds, justifies its name, but 
almost puts its body out of countenance, seeing that the 
arms in question are nearly four times as long as either 
the length or breadth of the carapace. In Lambrus inter- 
medius, Miers (see Plate IV.), from the Corean Seas and 
‘Torres ‘Strait, the disproportion between legs and trunk is 
less exaggerated, In the genus at large” it is remarked 
that, apart from larval metamorphoses, so many variations
