THE CRUSTACEA 173 



of short hairs, very closely set, looking exactly like a good 

 quality thick-piled velvet. The back is also raised into 

 a number of conelike processes, touching at their bases, 

 in symmetrical pattern. It is a very beautiful crab. The 

 usual colour is a light brown or buff, but I have had speci- 

 mens of a uniform deep crimson. 



Still in the Maidce are two forms found in deep water, 

 rarely on shore. These are Hyas araneus and Hyas- 

 coarctatus. These are without hairs, and the spinous pro- 

 cesses are fewer. The lateral spines are flat, and projecting 

 forward. The first-named is about two inches across the 

 back, the last is about half this size. They are of brick- 

 red colour. 



Eurynome aspera is a peculiar member of the same 

 family. It is only about half-an-inch across, without 

 hairs or spines, but very angular, and closely tuberculated, 

 as if it were built up of grains of gravel cemented together. 

 Its colour is grey, with red dots. It is found among 

 corallines low down in the littoral, and in deep water. 



The " slender-legged " forms (Leptopodiadce) are repre- 

 sented on our shores by several species ; Stenorhynchus 

 rostmtus is the best-known one. In this the body is 

 triangular, about three-quarters of an inch long ; the limbs 

 very long and slender ; the rostrum prolonged into a 

 simple sharp point, and the limbs very long and slender. 

 The crab with legs extended measures about four inches 

 across. Stenorhynchus phalangium, like the above, but with 

 a shorter and more obtusely pointed beak, is equally 

 common. 



A species which is considered rare, but which here is 

 far more abundant than either of the foregoing, is Stenorhyn- 

 chus Egyptius (Fig. 79). This is a beautiful form,, very 

 delicately fashioned, and with the rostrum long, down 

 curved, and in two parts, which terminate in front in one 

 sharp point. This one is plentifully covered with hooked
