250 Dr. W. C. Mcintosh'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 

 number of 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 Helsingfors. 



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 ; — Hipponoe Jeffrey sii^ n. sp. , 



a small Amphinomacean. 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'^] 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 Buskiij 

 n. sp., a species having the general aspect of 8. hoa rather than 

 that of S. MathildcBj 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. Eumenia 

 Jeffreysiiy n. sp., a form dredged last year in the Hebrides, but 

 too much decomposed to be minutely described : it is allied to 

 E. crassaj but there are no traces of branchial filaments. 

 Pr axilla artica (?Mgrn.), a species that very probably is P. 

 artica^j Malmgren ; but as that author 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. 

 Poly cirrus (?) trihullata^ n. sp., a species having the snout and 

 tentacles of a Polycirrus^ but without bristles or hooks in the
