166 E. ELLINGSEN ON 



The sexual area of the <$ proves that the species belongs to 

 the cancroides group ; the coxae of the fourth pair of legs strongly 

 curved. 



In 3, the claws of the first pair of legs are very little curved, 

 much straightened ; the exterior claw, along nearly the whole 

 inner margin, may be provided with a great number of small, 

 pointed teeth; in some specimens only the central part has these 

 teeth ; which, according to Mr. Wallis Kew, are sometimes very 

 indistinct. The first leg in $ is altogether of greater strength 

 than that of $ , the tibia more tumid, as also is the tarsus, and 

 the claws are larger. Coxal sac present. 



I have examined ten specimens, five of each sex, from England : 

 Lincolnshire, where Mr. Wallis Kew has found the species plenti- 

 fully on the sand dunes of the coast, over an area of nearly thirty 

 miles. Mr. Wallis Kew has examined the type in the British 

 Museum. 



There is certainly no doubt that the above list of synonyms is 

 correct ; in other words, that C. Schafferi and C. Degeeri are 

 synonymous with C, Latreillii, the species thus having a vast 

 distribution.

 pi. xviii., f. 21. 



E. Simon's description of this species may be supplemented 

 thus : 



Two eyes, more or less distinct. All eleven tergites are visible 

 from above ; the last, or the last two, are entire, the rest 

 divided longitudinally by a fine stripe. The movable finger of 

 the mandibles is somewhat truncated in the extremity; in $ 

 the galea consists of three stemlets, simple and arranged in a 

 row ; in <$ the galea is smaller, and consists of but a single 

 stemlet. There is but little difference between the sexes, except 

 in the sexual area ; the $ appears to be somewhat smaller than 

 the ?.
