408 CRUSTACEA. 



(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 Remipes marmoratus of Hombron and Jacquinot (Voy. au Pole 

 Sud., pi. 8, f. 22-26) has the outer antennae very much more slender 

 than in the pacificus. 



REMIPES HIRTIPES. 



Carapax paulo latior, suturd transversd non notatus. Denies 4 frontales 

 obtusi, externi vlx prominuliores, mediano fere obsolete. Oculi per- 

 parvi, paulo exserti, basi antennarum primarum valde breviores. Atir 

 tennce primce fere dimidii carapacis longitudine, flagellis subcequis, 

 setis flagelli minoris paulo longis. Pedes antici valde hirti. 



Carapax rather broader than in preceding species, not marked with a 

 transverse suture near middle. Four frontal teeth obtuse, the 

 outer hai'dly more prominent, a median tooth nearly obsolete. 

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

 antennae. First antennae about half as long as carapax, flagella 

 nearly equal, setaa of smaller flagellum two or three diameters of 

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