with relatively high epimera. Lateral corners of head 
prominently projecting, but rounded at point. First pair 
of epimera considerably smaller than the rest, and more 
slender below. Lateral plates of 4th abdominal segment 
but little produced posteriorly, acute-angled; 4th segment 
hunched above. Xo eyes. Antennae uniform in length ; 
1st pair with flagellum considerably longer than peduncle; 
secondary flagellum exceedingly slender, three-jointed. Oral

of legs rather slender, basal joint oval in form. Telson 
triangular, longer than trunk on last pair of caudal stylets, 
and cleft almost to the base. Colour whitish. Length

Remarks. — The present species I refer here to 
Boeck’s genus Tryphosa. In my judgment, however, both 
this genus and the genera Onisinms and Orchomene should, 
perhaps, more properly be eliminated and their species ranged 
under the genus Anonyx. From the other forms referred 
by Boeck to tlm genus Tryphosa, the present species may 
be recognized by the total absence of eyes, the remark- 
ably slender secondary flagellum on the 1st pair of antennse, 
and the form of the head.

Description of the Female. — The body (see PI. 
XIII. fig. 2) a good deal compressed from the sides, with 
relatively deep epimera and the oral region prominently 
projecting. 
The head has the lateral corners rather prominently 
projecting, though not pointed, as in the species previously 
described, but more linguiform in shape, with the extremity 
obtusely rounded. 
The 1st pair of epimera are appreciably smaller than 
the rest, and taper somewhat from below; the 4th pair are 
deeply cmarginate posteriorly, and beneath the emargina- 
tion produced to a sharp corner; the 5th pair about uni- 
form in height and breadth. 
The lateral plates of the 3rd abdominal segment are 
but little produced posteriorly, constituting merely an acute 
angle. The succeeding segment projects, hunch-shaped, 
above. 
Of eyes in the recently taken specimen, not a trace 
could be detected.
