THE GEE AT WAETY CEAB 121 



additions to the type species Eurynome 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. Eurynome tenuicornis, 

 Malm, from Bohusliin, Gullmarsfjord, is there found to- 

 gether with Eurynome aspera. 



Parthenope, Fabricius, 1798, has in its type species, 

 Parthenope horrida (Linn.), an animal of truly remarkable 

 appearance. It is recorded from the West and East 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 algae. 



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, Stimpsou, and 

 Mesorhoea, Stimpson. The species are distributed over all 

 the warmer seas of the world, and some occur in the Medi- 

 terranean. Of these Lambrus macrochelos (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
