nearly as long as body, last joint longest, acute, fourth shorter than 

 third. Sixth pair long, but shorter than fifth, first joint large and 

 nearly elliptical, second small, third large subelliptical, with the 

 outer extremity deeply excavate (for articulation with next joint), 

 posterior apex acute, anterior obtuse, fifth joint a little longer than 

 fourth, and inner margin minutely serrulate, claw short. Seventh 

 pair slender, the coxa much shorter than the following part. 



Plate 69, fig. 2 a, animal, enlarged; b, anterior antenna; c, extre- 

 mity of abdomen. 



Atlantic, latitude 1° south, longitude 18° 20' west. Collected, 

 November 5, 1838, at 4 A. m. 



Length, two lines. Mostly colourless, excepting a few brownish 

 spots, and a black spot at base of each of the ten posterior thoracic legs. 

 Head placed obliquely, so that the buccal extremity is thrown some- 

 what forward; the whole covered with facets. Pigment of eyes 

 angular in form, upper line straight and nearly horizontal, the whole 

 situated low in the head, appearing just above the mouth. Anterior 

 antennae with a stout oval base, which is three-jointed, the last joint 

 having five transverse lines or articulations, hirsute about apex, and 

 a lateral appendage, which is quite small and three-jointed. Only 

 five joints of the thorax are distinct, and these are nearly of equal 

 length (the posterior slightly longest); only one was observed anterior 

 to these, and this was partly concealed at its upper part, beneath the 

 third segment; it appeared to correspond to first and second segments. 



The anterior feet are a little shorter than second pair, and the 

 claws turn downward, and the third and fourth pairs are much longer 

 than second. The fifth is very slender and has an acicular extre- 

 mity. The fourth and fifth joints of sixth pair are subcylindrical, 

 and the claw is hardly a fourth as long as preceding joint. Seventh 

 pair has the fourth joint longest. Abdomen five-jointed, the last ob- 

 long, broad, compressed, truncated at apex, and having an indistinct 

 suture near base ; bears second and third pairs of stylets. Stylets ex- 

 tend about equally far backward, last pair attached to apex of last 

 abdominal segment, and having basal portion very short, not oblong; 

 branches of stylets finely serrulated at one or both margins. In second 

 pair of stylets the branches are a little shorter than basal portion.
