250 Dr. W.C. M‘Intosh’s Report on the Annelids 
The Annelids found in the deep water off North Unst form 
a collection very rich in new or rare forms; for, out of thir- 
teen species, three at least are new to science, and four not 
hitherto found in Britain. The collection from the Outer 
Haaf, Skerries, has also several rare forms; out of eight, four 
are new to Britain and one to science. Out of sixty found 
in St. Magnus Bay, four are new to science and eighteen to 
Britain. These figures contain the entire new or rare forms 
in the individual collections, without reference to their occur- 
rence in others, as will be apparent when I mention that, out 
of a total of about ninety-two Annelids at present identified, 
five or six, so far as I can make out, are new to science, and 
about twenty-two to Britain. As before stated, this is one of 
the best collections of the kind ever made in Britain, whether 
we regard the excellent condition of the preparations or the 
numberof new forms. As might be expected, many of the 
additions to our fauna are Scandinavian in type; but others are 
not so, at least they do not occur in the valuable catalogue 
recently published by Dr. A. J. Malmgren, the enterprising 
naturalist of Helsingtors. 
I have described some of the supposed new forms elsewhere, 
and therefore shall merely name them; others have not yet 
been noticed. They are as follows :—Hipponoé Jeffreysit,n.sp., 
a small Amphinomacean. Hunoa , the second species of 
the genus found in Britain, the first being 1. nodosa, Sars, 
also found in the Shetland seas by Mr. Jeffreys, and described 
by Mr. Lankester as a new form, under the name of Antinoé 
zetlandica*; 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. Stgalion Buskit, 
n. sp., a species having the general aspect of S. boa rather than 
that of S. Mathilde, to which the scales are most nearly allied 
in structure ; but the bristles are longer than in either case, and 
characteristically different. Notocirrus scoticus,n.sp.,a Lumbri- 
nereian with a dorsal branchial lobule to each foot. Humenia 
Jeffreysit, n. sp., a form dredged last year in the Hebrides, but 
too much decomposed to be minutely described: it is allied to 
i. crassa; but there are no traces of branchial filaments. 
Praxilla artica (?Mgrn.), a species that very probably is P. 
articat, Malmgren; but as that author has only mentioned 
that it is similar to P. pretermissa (differmg in the hooks 
having six teeth), we are left quite in doubt as to his form. 
Polycirrus (2) tribullata, n. sp., a species having the snout and 
tentacles of a Polycirrus, but without bristles or hooks in the 
* Trans. Linn. Soe. vol. xxv. p. 377, tab. 51. figs. 13, 17, 18, 22, & 23.
