336 REPORT 1868. 



the Anonyx longicornis, which differs from Anonyx in having no 

 secondary appendage to the upper antennae. 



" Unciola leucopes, Kroyer." B. & "W. consider my U. planipes as " probably 

 identical " with this species. It may be so, but there are points of dif- 

 ference which made me think it wiser to keep them apart until the ex- 

 amination of Greenland specimens should settle the question definitely. 



" Hyperia tauriformis, n. sp." This is the Metoecus medusarum of Kroyer 

 and of this Eeport. B. & W.'s specimens were from Banff, forwarded 

 by Mr. Edward, to whom I am also myself indebted for specimens. 

 In the ' Annals and Mag. Nat. Hist.' for January 1869, p. 49, pi. viii. 



figs. 13-15, will be found a description of Cytlieruraflavescens, by Mr. G. S. 



Brady ; and in the ' Quart. Journ. Micros. Science,' January 1869, a full 



account by Prof. Allman of Rliabdopleura Normani. 



Report on the Annelids dredged off the Shetland Islands by Mr. Gywn 

 Jeffreys, 1867-68. By W. C. M'INTOSH, M.D., F.L.S. 



GWYN JEFFREYS, in his dredging-expedition to the Shetland Islands 

 last year, kindly selected, chiefly with the assistance of Mr. Sturges Dodd 

 and the Rev. A. M. Norman, a large number of Annelids, which he most 

 courteously placed at my disposal ; and, as they were properly preserved in 

 vessels and fluid sent for the pupose, their subsequent examination proved 

 very satisfactory. The same was done in 1868 ; but owing to the unfavour- 

 able state of the weather, the collection was very much smaller than that of 

 the previous year. 



The majority of the Annelids come from St. Magnus Bay, or, rather, from 

 the deep water (80-100 fathoms) beyond this, not because they so dispro- 

 portionately abound there (although the muddy sand is eminently favourable 

 for their increase), but probably because the dredging was most frequently 

 carried on in that neighbourhood. The other localities, in the order of the 

 respective collections, are off Balta, North Unst, Bressay Sound, Outer Haaf 

 (Skerries), Fetlar, and a small shore collection made by Mr. Dodd at Hills- 

 wick. 



The Annelids found in the deep water off North Unst form a collection very 

 rich in new or rare forms ; for, out of thirteen 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 

 occurrence 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 at present 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 in regard to the excellent condition of the prepara- 

 tions or the number of new forms. As might be expected, many of the 

 additions to our fauna are Scandinavian in type ; but others arc not so, at 

 least they do not occur in the valuable catalogue (Annulate Polycheeta Spets- 

 bergia3, <fcc.) recently published by Dr. A. J. Malmgrcn, the enterprising 

 naturalist of Helsingfors.
