Cephalotliorax regularly ovate, rounded in front, and having a short 

 beak, segments not appearing acute at their posterior angles in an 

 upper view. Abdomen somewhat abruptly smaller than last tho- 

 racic segment, and gradually decreasing in breadth, five-jointed. 

 Anterior antennae short, scarcely exceeding one-half the length of 

 cephalothorax, nine-jointed, basal joints four in number, rather 

 stout, second largest, setae very short. First pair of feet small, move- 

 able finger rather more than half the length of the preceding joint. 

 Caudal stylets very short, a little divaricate, second seta as long as 

 the body, first and third subequal, much shorter than abdomen.

Island of Madeira, in pools on the rocky shores, containing sea- 

 weed, below high water mark. 



Length, one-twentieth of an inch. Colour, light greenish, or colour- 

 less. Length of cephalothorax, about twice its breadth. Abdomen as 

 broad at base as one-third the breadth of anterior part of cephalo- 

 thorax. Eyes with the spot of pigment large, red. Anterior an- 

 tennae not as long as the first segment of the body; last five joints 

 minute, setigerous appendage one- or two-jointed, and bearing setae, 

 which included make it as long as the main branch. Posterior an- 

 tennae five-jointed, last three joints oblong, the last a little clavate. 

 Mandible having an obliquely truncate summit, which is furnished 

 with four or live teeth on the edge above, and two sharp processes at 

 the commencement of the truncation. Only the last three joints 

 (all ?) of the maxillipeds were observed ; these organs terminate in a 

 slightly curved claw of rather large size, and have a setulose jointed 

 appendage to each side of third joint, one of which extends as far as 

 apex of claw ; when projecting over the claw, the claw appears to be 

 ciliated, and it was so viewed at first. Branches of second pair of
