374 W. C. M‘INTOSH ON BRITISH ANNELIDA. 
APHRODITID. 
In the Catalogue of the British Museum three species of this group are described, 
viz. Aphrodita aculeata, L., A. borealis, Johnst., and Hermione hystrix, Sav. An 
examination of Dr. Johnston’s specimens from Berwick Bay (in the British Museum) 
shows that his A. Jorealis is the young of the first mentioned. A third species 
(Letmonice filicornis, Kbg.) is not uncommon from Shetland to the Atlantic south 
of the British Channel. 
POLYNOID#. 
Eight species are indicated in the Catalogue, viz. Lepidonotus squamatus, L., L. clava, 
Mont.', Evarne impar, Johnst., Eunoa nodosa, Sars (as L. pharetratus, Johnst.), Dasy 
lepis asperrima, Sars (as L. pharetratus, Baird), Lagisca propingua, Mgrn. (as Lepido- 
notus semisculptus), Nychia cirrosa, Pallas (as L. imbricatus), and “L. pellucidus,” 
probably a young form of some of the foregoing. ; 
Evnoa noposa, Sars, was first dredged by Lieut. Thomas, and termed by Dr. Johnston 
I. pharetratus; Prof. E. Ray Lankester, from a specimen procured in Shetland by Dr. 
Gwyn Jeffreys, named it Antinoé zetlandica. It has a very wide range. Dr. Malmgren 
vouches for the specimen in the British Museum; and accordingly, though it is in bad 
condition (apparently having been dried), it has been figured. A dorsal bristle is 
represented, Pl. LX VII. fig. 4, and a ventral in fig. 5, both mounted in balsam, fig. 6 
being another in water. The bristles of a specimen from the coast of Durham are given 
in Pl. LXVII. figs. 7, 8, the former representing the dorsal, the latter the ventral. 
DASYLEPIS ASPERRIMA, Sars. This was first recognized as British by Dr. Malmgren 
(in the British Museum, where it was labelled Lepidonotus pharetratus). The specimen 
had been sent to the late Dr. Baird by Mr. D. Robertson from the Frith of Clyde. 
The great density of the dorsal tufts of bristles gives the animal a woolly appearance ; 
and their ferruginous colour is also peculiar. The length of the example is about 
one inch. The head has two large eyes at the posterior border, and one on each side 
on the median prominence. The scales are roundish in front, reniform posteriorly, 
and boldly armed on the posterior and outer margins and the neighbouring surface 
' The Aphrodita punctata of O, Fabricius may be this form; but it is doubtful what connexion the Z. punc- 
tatus of (Brsted in his ‘Grénlands Dorsibr.’ has with it. He evidently means the common Z. squamatus in his 
‘Annulat. Danie.’ The Polynoé fuscescens of De Quatref. (Annél, i. p. 242) appears to be intimately allied to 
L. clava; and the same may be said of his P. modesta and the P. clypeata of Grube, The Polynoé levis of 
Aud. & Ed. (ineluding in the diagnosis the allusions afterwards made to it by H. Rathke, M. Sars, and De 
Quatrefages), does not seem to be this species; indeed I haye sometimes thought, from the descriptions of 
Audouin & Edwards and De Quatrefages, that this P. levis might be a variety of P. setosissima with fourteen 
pairs of scales. The P. grubiana of Claparéde may be a variety of Z. clava, since he does not distinguish it 
from the latter while contrasting it with Z. squamatus.
