Locality. — Stat. 248. 
Remarks. — From the typical species, this form is 
easily distinguished by the rough surface of the integuments, 
the less produced 2nd pair of antennae, and the rudiment- 
ary character of the caudal appendages; finally, not only 
by the 1st, but also the 3rd, segment projecting on either 
side as an acute spine. 
Description of the Female. — The body (PI. XI, 
fig. 26) has the slender and elongate form peculiar to the 
genus, with the greatest breadth scarcely exceeding one- 
fifth of the length, the medial part remarkably narrow and, 
as it were, drawn out. 
The integuments are rather compact, and everywhere 
rough, from minute appressed spines, or spicules. 
The head is comparatively small, almost circular in 
shape, and at the base partly encompassed by the 1st free 
segment, with the frontal margin uniformly arched. 
The 3 first segments are well-nigh uniform in size, 
a, nd more than twice as broad as long. I he anterioi lat- 
eral corners of the 1st and 3rd jut out as long, oblique, 
anteriorly directed, dagger-shaped projections, those on the 
1st segment in particular being of very considerable size. 
The 2 succeeding segments exhibit a very peculiar 
form, constituting together an exceedingly elongate and, in 
the middle, narrow-cylindric, or almost hourglass-shaped 
section of the body, that measures about one-half of the 
total length. The two segments arc very firmly, and, it 
would seem, immovably connected with each other, though 
distinctly defined by a straight, transverse suture, occurring 
somewhat anterior to the middle of the aforesaid section. 
The 2 last segments belonging to the anterior division 
are very small, with uniformly rounded lateral parts and 
the posterior margin somewhat concave. 
The abdominal segment is comparatively small, mea- 
suring not more than one-seventh of the total length. In 
form it is oval, somewhat constricted at the base, and with 
the extremity obtusely pointed. 
Of eyes no trace whatever could be detected. 
The 1st pair of antennae (fig. 27) are about as long 
as the head and the 2 first segments taken together. The 
1st joint of the peduncle is extremely short, squamiform, 
with a somewhat jagged margin. The 2nd joint is greatly 
produced, and slender, as also, along the inner margin, 
furnished with 4 strong bristles. The 3rd joint is com- 
paratively small, and would appear rather as belonging to 
the flagellum than to the peduncle; it is succeeded by 3 
short articulations, representing the true flagellum. 
The 2nd pair of antennae (fig. 26) is much stronger 
in development, though scarcely attaining the length of the 
bodv The 5 joints of the peduncle are all slender and
