Glycera, Savigny. 
Glycera tesselata, Grube (PI. XLII. fig. 5). 
Habitat. — -Dredged at Station 75 (off" Fayal, iii the Azores), July 2, 1873; lat. • 
38° 38' N., long. 28° 28' W., depth, 450 fathoms ; surface temperature 70°‘0 ; sea-bottom, 
volcanic mud. 
A specimen of medium size (about 48 mm. long and 6 mm. in breadth at its widest 
part). It is incomplete posteriorly. 
The snout has more than the thirteen rings mentioned by Ehlers, but he also 
indicates doubts on this , point. Sixteen or seventeen rings appear to be present in this 
form. In the toughness and aspect of the skin it approaches Glycera ca'pitata. No 
eyes are visible. 
A form very similar to the foregoing occurs at Station 142 (off the Cape of Good 
Hope), December 18, 1873 ; lat. 35° 4' S., long. 18° 37' E.; depth, 150 fathoms; bottom- 
temperature, 47°’0 ; sea-bottom, green. It agrees closely with the typical Glycera 
tesselata, Grube, except in the presence of dusky yellowish pigment at the tips of the 
feet, especially in front. 
A curious feature in this example is the occurrence of numerous minute Nematoids 
in little masses of epithelial debris in the extruded proboscis. 
In the body-cavity of the s 2 Decimen from Fayal a membranous mass contained 
numerous dark grains ( 2 >robably cinders), sand particles, one or two Foraminifera and 
sponge-spicules, and tufts of the bristles of a Glycera, which had escaped b}^ rupture 
from the alimentary canal. 
In a transverse section of the middle of the extruded proboscis of the same example, 
. the regularity of the muscular bands is noteworthy. Beneath the densely jjapillose inner 
surface is a series of fibres which have internally lozenge-shaped spaces between the 
longitudinal bundles. The latter are rounded externally, flattened internally, and the cut 
ends of the fasciculi have a somewhat radiate arrangement. Between the outer invest- 
ment and the former coat is a strong circular layer. The posterior region of the pro- 
boscis forms a quadripartite series of folds, which evidently have a thick cuticular covering. 
The distribution of Glycera tesselata would appear to be wide, for it stretches from 
the Shetland Islands to the Madeiras. 
Glycera capitata, (Ersted.

mud.
