Farven. Kroppen lys gulbrun med lidt mørkere Ten- 
takler. Skjoldene mørkebrune. 
Kun et Exemplar blev fundet paa 87de Station., 
Artskarakter. 
Kroppen eylindrisk, 8”” lang, bedækket af større og 
mindre Chitinplader; den bagerste Ende tværs atskaaren. 
Snabelen dobbelt saa lang; som Kroppen, overalt besat med 
Hager og forsynet med 10—12. korte Tentakler. Ende- 
skjoldet rundt, næsten fladt, sammensat af Chitinplader, dey 
i Randen ere tungeformede, i Centrum runde. Udenom 
Skjoldet 6 Ringe, besatte med Plader. Det forreste Skjold 
omvendt hjerteformigt. 
Af de hidtil beskrevne Arter af Slægten Aspidosiphon 
kommer armatum nærmest den af Dr. Théel* beskrevne 
Asp. mirabilis; men den adskiller sig fra denne derved, at 
Snabelen er meget længere og overalt besat med Hager, at 
Skjoldene have, en noget forskjellig Form, og at Chitin- 
pladerne, hvorat disse ere sammensatte, ere forskjellig ordnede. 
Destoværre havé vi kun havt 1 Exemplar til voré 
Undersøgelser, der som Følge deraf ikke ere blevne saa 
udtømmende, som vi kunde ønske; men se vi hen til de 
Beskrivelser, * der ioreligge over Slegten Aspidosiphon og 
dens Arter, ere vi tilbøielige til at tro, at ogsaa de Forskere, 
som tidligere have beskjeitiget sig dermed, have ligesom vi 
manglet Materiale; thi ellers vilde sikkerligen Beskrivelserne 
have’ været mere tuldstændige, end de ere.

Stretehing along the spiral of the intestine, and attached to 
the æsophagus, was seen a flat, whitish-yellow body, which, on 
closer inspection, proved to, be the ovary, fig. 6, 2, contain- 
ing ova in various stages ot deyelopment; and numbers 
of isolated ova were iound floating in’ the perivisceral 
cavity. The ova of this animal, measuring 0.136” in 
length and 0.1127" in breadth, are flat, discoid, oval, with 
a slightly acuminate extremity; they have a germinal vesicle 
and a germinal speck, and for the rest resemble the eggs 
ot Phascolosoma. 
Two tree depending segmental organs, brown in colour,

The nervous chord protends between the roots of 
the: retractor along the ventral suriace to the anterior ex- 
tremity of the esophagus, which it annulates. 
Colour. — Body light yellowish-brown, with somewhat 
darker tentacles. The shields dark-brown. 
One specimen only was brought up, at Station 87 
Specific Character. 
Body eylindrie, 87” long, covered with chitinous plates 
Pro- 
boscis, twice the length of the. trunk, studded all over 
of varying magnitude; posterior extremity’ truncate. 
with chitinous hooks, and furnished. with 10 or 12 short 
tentacula. + Terminal shield round, almost flat, composed of 
chitinous plates, which at the margin ot the shield are lingui- 
form, at the centre round. Round about the shield, 6 an- 
nular bands covered with plates. Foremost shield inverted 
cordiform. 
Of the species belonging to the genus Aspzdosiphon 
as yet described, Asp. armatum bears the closest resemblance 
to Asp. mirabilis, described by Dr. Théel,* but is distinguished 
from it by having a much longer proboscis, studded all over 
with chitinous hooks; the the two 
species differ somewhat in form, and the arrangement of the 
moreover, shields in 
chitinous plates composing them is different. 
Untortunately, we have had only one specimen on 
which to base our observations; and hence they are less 
exhaustive than we should have wished them to be; but, 
callmg to mind the descriptions previously furnished of the 
genus Aspidosiphon and its species, the naturalists who have 
made these animals the subject of investigation, would, 
like ourselves, appear to have lacked suificient materials; 
otherwise their descriptions had certainly approached nearer 
to completeness
