500 DR. W. C. M'INTOSH ON THE ANNELIDA 



fauna of the region. Prom the works of Dr. Malmgren the list published in the ' Arctic 

 Manual ' for 1875 was drawn up by Dr. Liitken, of the University Museum, Copenhagen. 

 The list comprises 101 species of marine Polyckseta. The remarks on the Annelids of 

 Novaia Zemlia by Dr. Ehlers *, and those of the Siberian Seas by Prof. Grube f, show 

 that not a few forms have a wide range in the arctic waters $. 



Though an accident which happened to the ' Valorous ' § prevented the extensive 

 dredging operations contemplated by Dr. Jeffreys, and limited the species of marine 

 Polychseta to about 68, yet of this comparatively small number 13 are new to the 

 Greenlandic area, and, in addition, about 9 are new to science. Pinally, so far as our 

 present knowledge of the Annelids goes, there is no doubt that Dr. Jeffreys's opinion 

 that the Greenlandic Invertebrates are more European than American, is substantiated. 



Euphrosyne borealis, (Erst. Station 1, 70° 30' N., 54° 41' W., off Hare Island, 

 Disco, 175 fathoms, on a bottom of sandy mud. The specimens measured about an 

 inch in spirit, with 25 body-segments, besides the first and last. The branchise in the 

 rows agreed with the description of Prof. M. Sars (viz. 7 or 8 in each row), though 

 sometimes one or two were deficient. Some are simple, the majority bifid, and that 

 nearest the median line generally trifid. The bristles are much more prominent organs 

 than in JE. foliosa, Aud. & Ed. ; and the spur on the smooth kind is much shorter. The 

 bifid bristles, again, have bolder transverse serrations. E. foliosa occurs abundantly 

 between tide-marks in Herm, whereas the arctic species frequents deep water, and 

 ranges to Spitzbergen and Pinmark. No example has yet been found in British waters. 

 Amongst the bristles are many specimens of a small red mite. 



The form of the branchise seems to be very characteristic in the British forms, viz. 

 E. foliosa, Aud. & Ed., and E. armadillo, Sars. 



Nychia ctrrosa, Pallas. Pine specimens from Holsteinborg Harbour, from 7 to 35 

 fathoms. This form has a wide range, from British waters to Scandinavia, Iceland, 

 Spitzbergen, and the Gulf of St. Lawrence. 



Ntchia Amondseni, Malmgren. Station 3, 69° 31' N., 56° 1' W., sandy mud, 100 

 fathoms, and Godhavn Harbour, Disco, in 5-20 fathoms. A common species in the 

 Gulf of St. Lawrence, Canada. 



EinsroA (Erstedi, Malmgren. Holsteinborg Harbour, in 35 fathoms. The specimens 

 measure an inch and three quarters long, and are larger than those from Canada. It 

 ranges to Iceland, Spitzbergen, and Pinmark. 



Harmothoe imbricata, L. Station 4, 67° 50' N., 55° 27' W., 20 fathoms on shell- 

 sand ; station 5, 66° 59' N., 54° 27' W., 60 fathoms on sand and shells; Holsteinborg 

 Harbour, 7-35 fathoms; outside Godhavn Harbour, in 80 fathoms; station No. I. 

 H.M.S. ' Alert,' 65° 00' N., 53° 00' W., 30 fathoms, on a rocky and gravelly bottom. This 

 ubiquitous form is abundant ; and there is nothing peculiar in size or coloration ; indeed
