ON THE ANNELIDS OF THE SHETLAND ISLANDS. 337 
I haye described some of the supposcd new forms elsewhere, and therefore 
shall refer to them very briefly at present. They are as follows :—Hipponoé 
Jeffreysii, n. sp., a small Amphinomacean with a simple subulate antenna on 
the smooth clevation of the dorsum of the head. There is no carunele. 
The branchi consist of tufts of simple processes, or they are bifid or some- 
what fasciculated. The bristles of the superior lobe of the foot are for the 
most part shorter and stouter than the inferior, and of a characteristic shape. 
It is allied to the Hurythoé borealis of Sars. Hunoa , the second 
species of the genus found in Britain, the first being ZH. nodosa, Sars, also 
found in the Shetland seas by Mr. Jeffreys, and described by Mr. Lankestcr 
as a new form, under the name of Antinoé zetlandica (Linn. Trans. vol. xxv.) ; 
in the present species the scales are quite smooth, often bordered with a dark 
pigment-belt, and the inferior bristles of the feet have an entire clawed tip. 
Sigalion Buskii, n. sp., a form having the aspect of S. boa rather than that of 
S. Mathilde, to which the scales are most nearly allied in structure ; but the 
bristles are larger than in either case and characteristicallydifferent. Notocirrus 
scoticus, n. sp., a Lumbrinereian, with a dorsal branchial lobule to each foot, 
and found abundantly in comparatively shallow water in the Hebrides, where 
the bottom is clayey mud. Humenia Jeffreysii, n. sp., a form first dredged 
by Mr. Jeffreys in the Hebrides, but too much decomposed to be minutely de- 
seribed: it is allied to &. crassa; but there are no traces of the branchial fila-. 
ments in any specimen. A double row of isolated papille runs along each 
side from the snout to the tail, the summit of each giving exit to a bundle of 
forked and simple bristles. Prawilla artica (? Malmgren), a species that 
yery probably is P. artica of that author; but as he has only mentioned that 
it is similar to P. pretermissa (differing in the hooks having six teeth), we 
are left quite in doubt as to his form. The tecth of the funnel are in general 
more filiform and distinct than in P. pretermissa. Polycirrus(?) tribullata, 
n. Sp., a species having the snout and tentacles of a Polycirrus, but without 
the bristles or hooks in the anterior region, which is furnished with three 
circular and somewhat flattened papille on each side. 
Of the forms new to Britain are—Letmonice filicornis, Kinberg, which, 
however, is Dr. Baird’s L. Kinbergi. Harmothoé longisetis, Grube, a widely 
distributed species, described by Mr. Lankester as H. Malmgreni (op. cit.), 
and therefore previouly found in Britain. Panthalis Girstedi, Kinberg, a 
fine species with the habit of a Sigalion. Sigalion limicola, Ehlers, a 
form found by its discoverer in the Adriatic. It is rather abundant in the 
Shetland seas, but, so far as known, has not yet been found on any other 
part of the British coast. The anterior scales are furnished towards the 
outer margin with peculiar ragged processes. It has four eyes, and not two, 
as stated by Dr. Ehlers, Nephthys ciliata, Miller. Genetyllis lutea, Malm- 
gren. Anaitis kosteriensis (?), Malmgren. Lumbrinereis fragilis, Miller, 
aspecies which probably includes L. tricolor and some others, and therefore has 
been found previously on the British coast. It ranges from the Channel Islands 
the north of the Shetlands, and large specimens occur at both extremities. 
Onephis sicula, De Quatrefages, a curious species (inhabiting a tube composed 
of shcil-fragments, stones, and sand), allied to Hyalineccia tubicola, but differ- 
ing entirtly in the structure of certain of its bristles and hooks, and in the 
absence of the small brush-like bristles. It is not uncommon on the south 
coast of England, as well as in the Mediterranean. Hone Nordmanni, Malm- 
gren, a species having the aspect of Goniada maculata, but differing amongst 
other particulars in the structure of the bristles of the dorsal lobe, which end 
in a somewhat blunt tip, furnished with a translucent conical apicial pro-
