Dark blue. Jlody elongate, narrowinn posteriorly (fin. -V-i). ]\ves on
black patches, S -f S (fip. 84); the two inner proximal eyes of each side smaller
than the others; the three posterior eyes in ;i proup apart from the five anterior,
rostantennal organs (fip. ;U> elongate, suliellii)tical, einht or nine times as lonp
as i)road. and four times as Ions: as the diameter of an adjacent eye; sometimes
constricted near the middle, .\ntenna' shorter than the head, with scfimenls in
relative lengths about as !»:1;):1(»:H». Sense orfian of third ;inteiin,il setiment
(fifl. I{.')) consisting of a pair of slender curvinji sense rods, subtended by a thick
chitinousridKe, and covered with an inteKumental fold. Fourth anteimal segment
with subapicai i)ai)ill;i ,intl with sleiuler curving sensory setae. Second, third,
and fourth abdominal scjiments sube<|ual in length dorsally. ( ienilal and anal
segments coTiHueiit. bearing two pairs of spines (fips. :j(i. :\7). Posterior si)ines
a little longer than hind ungues, feebly curving, on stout papillae almost half as
loll}!; as the spines. .Vnterior spines similar to the jiosterior, but a little shorter.
.\no-Kenital setjment with lonp stiff hairs jirojectiiin beyond the apex of the
abdomen, which are simple in some s])ecimens but ai)ically bent and knobbed
in others. Anus ventral. Unguis stout, untoothed i fin. :{S). rnpuiculus
extendinfj half to three-fifths as far as the unguis, lanceolate, acuminate. ( 'lavate
teiient hairs two, exteiidinn as far as, or farther than, the imnuis. Femur with
a siiifile lontr davafe hair [i\fi. '^'^). Furcula short, appended to the fourth
abdominal se(inieiit, and extending to the jiosterior margin of the third. Manu-
brium stout, with several pairs of dorsal seta' (fip. 'M). .Mucin and dens not
<lemarkated from each other. Mucro-deiites convergent, in form as in figs, 89
and 40; each with thi ■■ seta-: two dorsal and one ventral. Hand of tenaculum
bideiitate (fig. ;{0): eor|)Us with a single stout si la. (Jeneral clothing of few
short e(iual curving simjile seta' in the middle regi.'ii of each segment, with long
outstanding simi)le sensory seta' in a single transverse series on most of the body
.segments (fig. 41). Cuticula not tubercul.'ite, but figured. Length. l.S mm.

The term ./((/»;•('(/, as applied to the cuticula, means that the integument i.s
divided into minute polygonal areas.

In two speeiii'ens the long distal hairs of the abdomen were simple; in one
specimen, however, they were distinctly bent apically. with a minute terminal
knob, as in my fig. :{(). Linnanieini ('12. |). KM), not having seen the-e clavate
hairs as described by Schott, suggested that the appi'araiiee of terminal knobs
was ihie to adherent particles of foreign matter.
