464 GONIADA MACULATA. 



Skerries, 1868 (J. G. J.). St. Magnus Bay, Shetland, eighty to one hundred fathoms 

 (J. G. J.). Dingle Bay, Ireland, thirty to forty fathoms, stones and sand, ' Porcupine,' 1 869. 



Examples of the second type come from the Minch, off Bergen, Norway (A. M. 

 Norman). Denmark, Sweden, and Finmark. ' Porcupine,' 1870, at Station XVII a, in 

 795 fathoms, and in Bono Bay in twenty-five fathoms, and Station XXIX, 227 fathoms ; 

 bottom temperature, 53° P. North Sea (Ehlers). Madeira, where it is smaller than in 

 the North Sea (Langerhans). North America. Canada (Dr. Whiteaves). 



Head (Plate LXIV, figs. 6 and 6 a) forming a tapered or elongated conical process, 

 with four short cirri anteriorly, and consisting of eight segments. 



Body about 4 — 6 ins. long and of 194 segments (Ehlers), tapered at each end, but 

 much more distinctly so anteriorly, rounded in front, and becoming more flattened 

 towards the middle and posteriorly, and terminating in the vent, below which are two 

 cirri of moderate length. Female of a pinkish colour in front as far as the change in 

 the feet, then dusky brown, with a tinge of olive throughout the rest of its extent, the 

 dorsum being mottled with brown marked by pale lines and separated at each segment-

junction. Just in front of each junction a transverse line cuts off a narrow segment of 

 the brown pigment. The ventral surface is pale pink in front, greenish throughout the 

 rest of its extent from the large ova. These were extruded from the broken posterior 

 end of the animal, and had a very transparent capsule, with pale greenish yolk. The eggs 

 are comparatively large, though perhaps not quite ripe, and measure about *0105 mm. 

 No eyes. Six V-shaped denticles on one side and six or seven on the other in this 

 example. 



Another example, also a female (16th June, 1904), was of a fine scarlet colour, paler 

 towards the snout — which was pale at the tip and pinkish behind, and dull yellowish 

 towards the tail. The red colour seemed to be generally diffused dorsally and ventrally 

 over those parts having it, and was bright at the bases of the feet, which showed some pale 

 patches, giving them a mottled aspect. Anteriorly the iridescent dorsum was divided into 

 a median and two lateral areas, the latter striated by longitudinal creases in the segments, 

 but at the change of segments this ceased, the dorsum then showing a similar disposition 

 to that in the foregoing female, though the pigment was red, the narrow bar in front of 

 the segment- junction being distinct. This remarkable coloration does not appear to be 

 due to the perivisceral fluid, which was pale, but to pigment in muscles and other parts, 

 as further examination proved, for this was likewise loaded with pale greenish ova with 

 large nuclei. The muscles of the proboscis and other parts appeared to be reddish.
