Podocerus longicornis, Gr. 0. Sars. Crust. & Pyenog. nova etc., No. 38 
(non Heller). 
Specific Character. — Body less thickset, somewhat 
compressed, with well-developed epimera. Lateral corners 
of head greatly produced, and pointed. Lateral plates of 
3rd abdominal segment acute-angled posteriorly. Antenna* 
slender and exceedingly elongate, well-nigh equalling whole 
body in length, and furnished on posterior margin with 
long and delicate bristles; 1st pair with 1st joint of ped- 
uncle longer than head; secondary flagellum uni-articulate, 
half as long as 1st joint of flagellum; true flagella uni- 
form in appearance, five-jointed, and rapidly tapering. The 
2 anterior pairs of legs not very powerfully developed, with 
oval, unarmed hands; the 3 posterior al most equal in 
length. Caudal stylets slender. Colour uniform white. 
Length 3-™. 
Locality. — Stat. 295. 
Remarks. — This diminutive species is easily dis- 
tinguished from the 2 preceding ones by its remarkably 
elongate and slender antennae, furnished posteriorly with 
long fascicles of bristles, -by the greatly produced lateral 
corners of the head, and also by the comparatively feeble 
structure characterizing the foremost pair of legs. The specific 
designation “longicornis” having already been adopted by 
Heller for a Mediterranean species, I selected another, 
likewise derived from the structure of the antenna*. 
Description. - The body (see PI. XVII, fig. 3) occurs 
ther slender, and somewhat compressed from the sides, 
ith the back evenly arched and relatively high epimera. 
The head is shorter than both of the 2 formost seg- 
ents taken together, and has the lateral corners greatly 
reduced and acutely pointed. 
Of the epimera, the 1st pair are comparatively small, 
,ul in part covered by the 2nd; the 3 succeeding pairs, 
. thp 0 ther hand, are rather large, and appreciably higher 
ian the body. The lateral plates of the 3rd abdominal 
?gment are drawn out posteriorly to an acute-angled 
irner. . . 
Eyes entirely wanting; and no trace of pigment could 
e anywhere detected within the ocular area in the recently 
ikon specimen. 
The antenme are remarkably elongate and slender, 
rell-nigh equalling the whole body in length, and furnished 
the posterior margin with long, delicately curving 
sties The 1st pair have the 1st joint of the peduncle 
Appreciably longer than the head, the 2 succeeding joints 
ti 1 more produced and cylindric in form. As in the 2 
.receding species, the secondary flagellum is um-articulate,
