(third) not half longer than its breadth. First pair of legs have 

 the second joint very large and broad, the remaining three oblong, the 

 last longer than the other two, which are nearly equal. Last joint of 

 second pair of legs short pubescent on the margin. Last joint of 

 fourth pair slender, a little curved, short pubescent on inner side. 

 Fifth pair terminates in a small, imperfect hand ; the hand broadest 

 at apex and truncate nearly transversely; the short finger closing 

 against the terminal margin, and not quite as long as the margin ; 

 hairs about the extremity numerous, as long as the hand or even 

 longer. This pair extends up into the branchial cavity. 



No appendages to fourth abdominal segment (out of the six ob- 

 served) ; those of first and second segments long filiform, and sparsely 

 covered with long scattered hairs, a little curling; third pair slender 

 but short; last pair as in Hippa. Anus situated at centre of last 

 segment of abdomen. 



The Bemipes marmoratus of Hombron and Jacquinot (Toy. an Pole

 outer hardly more prominent, a median tooth nearly obsolete. 

 Eyes very small, but little exsert, much shorter than base of first 

 antennae. First antenna) about half as long as carapax. flagella 

 nearly equal, setae of smaller nagellum two or three diameters of 

 the organ in length. First pair of feet rough and unevenly hairy.
