extremity of the hand, being separated from it by a 

 concave space. The hand is much narrower than the 

 wrist, and the finger is long, and but slightly curved and 

 serrated ; the apex when closed impinges against the 

 extremity of the carpal process. The second pair of 

 legs have the wrists very long ; and the hand is scarcely 

 more dilated, but not longer than it is broad, the inferior 

 angle being produced to a strong thumb-like process, 

 separated from the finger by a wide palm : the finger is 

 slight and nearly straight, and falls against the extremity 

 of the thumb when closed. The next two pairs of legs 

 are slender, and the three last pairs gradually increase 

 in length posteriorly. The rest of the animal bears a 

 near resemblance to the species of Microdeutopus or 

 Aora. 



We received this very curious and interesting form 

 from Salcombe Harbour on the south coast of Devon- 

 shire, where it was taken by Mr. Webster.
