ON THE ANNELIDS OF THE SHETLAND ISLANDS. 337 



I have described some of the supposed new forms elsewhere, and therefore 

 shall refer to them very briefly at present. They are as follows: Hipponoe 

 Jeffrey sii, n. sp., a small Amphinomacean with a simple subulate antenna on 

 the smooth elevation of the dorsum of the head. There is no caruncle. 

 The branchirc consist of tufts of simple pi cesses, 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 Eurythoe borealis of Sars. Eunoa , the second 



species of the genus found in Britain, the first being E. nodosa, Sars, also 

 found in the Shetland seas by Mr. Jeffreys, and described by Mr. Lankester 

 as a new form, under the name of Antinoe 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 Buslcii, n. sp., a form having the aspect of S. boa rather than that of 

 S. Mathilda, to which the scales are most nearly allied in structure ; but the 

 bristles are larger than in either case and characteristic ally different. 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. Eumenia Jeffreysii, n. sp., a form first dredged 

 by Mr. Jeffreys in the Hebrides, but too much decomposed to be minutely de- 

 scribed : it is allied to E. crassa but there are no traces of the branchial fila- 

 ments in any specimen. A double row of isolated papillae runs along each 

 side from the snout to the tail, the summit of each giving exit to a bundle of 

 forked and simple bristles. Praxilla artica (? Malmgren), a species that 

 very probably is P. artica of that author ; but as he has only mentioned that 

 it is similar to P. prcetermissa (differing in the hooks having six teeth), we 

 are left quite in doubt as to his form. The teeth of the funnel are in general 

 more filiform and distinct than in P. prcetermissa. Poly 'cirrus (?) tribullata, 

 n. sp., a species having the snout and tentacles of a Poll/cirrus, but without 

 the bristles or hooks in the anterior region, which is furnished with three 

 circular and somewhat flattened papillae on each side. 



Of the forms new to Britain are Lcetmonice Jilicornis, Kinberg, which, 

 however, is Dr. Baird's L. Kinbergi. Harmothoe longisetis, Grube, a widely 

 distributed species, described by Mr. Lankester as H. Malmgreni (op. cit.), 

 and therefore previouly found in Britain. PanihcHis GErstedi, 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. NepJithys ciliata, Miiller. Genetyllis lutea, Malm- 

 gren. Ana'itis Jcosteriensis (?), Malmgren. Lumbrinereis fragilis, Miiller, 

 a species which probably includes L. tricolor and some others, and therefore has 

 been found previously on the British coast. It ranges from the Channel Islands 

 to the north of the Shetlands, and large specimens occur at both extremities. 

 Onupliis sicula, De Quatrefages, a curious species (inhabiting a tube composed 

 of shell-fragments, stones, and sand), allied to Hyalincecia tubicola, but differ- 

 ing entirely 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. Eone 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-
