54 Prof. M'Intosli's Notes from the 



Glycera dihranchiuta, Ehlers. 



1808. Glycera dibrancJtiata, Ehlers, Borsteiiw. ii. p. 670, Taf. xxiv. 

 figs. 1, 3-8, & 19-28. 



From Station no. 7, 1873, viz. between Anticosti and the 

 Gaspe Peninsula, in 100-220 fathoms, come one or two 

 examples of a species which most nearly approaches the 

 Glycera dibranchiata of Ehlers. The form is comparatively 

 small, none apparently exceeding^ 3 or -i inches in length. 

 The head appears to be typical, with numerous closely 

 arranged rings. The proboscis forms a boldly clavate organ 

 in extrusion, and the teeth at the end of the first region 

 can readily cross each other, dorsally and ventrally. The 

 papillae are elongate, and, by a constriction at the base, 

 somewhat elliptical. At the 10th foot, two long and some- 

 what lanceolate lobes occur in front, a short upper one 

 posteriorly, and below it a longer conical lobe. The ventral 

 cirrus is short and conical. The dorsal cirrus is above the 

 base of the foot and of same size. At the 20th foot the 

 chief change is the increase of the upper posterior lobe, 

 which is a flattened conical plate. The 30th foot presents 

 both a dorsal and a ventral branchia, and these are found as 

 far back as the 90th (PL IV. fig. 7), and probably behind 

 it in perfect examples. The size of the somewhat ovoid 

 dorsal cirrus remains considerable throughout. 



The only example of the Ariciidse is Scoloplos armiger, 

 O. F. Miiller, which was dredged at various stations in 1873, 

 viz., no. 15, in August, in the Baie des Chaleurs, between 

 Capes Despair and Grand; off Pabore, in 70 fathoms; off 

 Cape Hood, Cape Breton, in 45 fathoms, between Bradelle 

 Bank and Miscou Island. 



5. On the same Groups procured by Canon Norman, 

 D.C.L., F.R.S., in Norway and Finmark. 



Of the Goniadidse, Goniada maculata, QErst., and G. nor- 

 vegica, CErst., were obtained, and three of the Glyceridse, 

 viz. : Glycera capitata, ffirst., Glycera vjiicornis, Savigny 

 (= G. Goesi, Malmgren), and Glycera alba, H. Rathke. 

 Amongst the Ariciidae are Aricia Cuvieri, Aud. & Ed., 

 Aricia norvegica, Sars, and a form near Aricia Kupffcri, 

 Ehlers, from Norway, and Scoloplos armiger, O. F.* M,, 

 from Finmark. 



6. On some Japanese Glyceridse. 

 Four species of Glycera have recent) v been described
