. A B Fig. 40. Amphiporus schollaerti, A, ventral surface of head of preserved specimen; B, dorsal surface. Amphiporus schollaerti, (Figs. 40, 41). A single specimen (N 58) of a large worm was taken at St. 182 in the Schollaert Channel, Palmer Archipelago. The colour as noted in life was pale buff. The preserved specimen was 97 mm. long, and 5-0 mm. broad. It was almost round in section from one end to the other except the head which was blunt and flat (Fig. 40). There was a pore visible at the tip and a larger aperture just ventral to this. Lateral vertical grooves were also prese
. A B Fig. 40. Amphiporus schollaerti, A, ventral surface of head of preserved specimen; B, dorsal surface. Amphiporus schollaerti, (Figs. 40, 41). A single specimen (N 58) of a large worm was taken at St. 182 in the Schollaert Channel, Palmer Archipelago. The colour as noted in life was pale buff. The preserved specimen was 97 mm. long, and 5-0 mm. broad. It was almost round in section from one end to the other except the head which was blunt and flat (Fig. 40). There was a pore visible at the tip and a larger aperture just ventral to this. Lateral vertical grooves were also present, joining ventrally. The body was slightly dusky at the sides but otherwise colourless. The anatomy is similar to A. lecointei with the exception of the proboscis which has fourteen nerves. Head glands, cerebral subepithelial glands are present and the cerebral organs occupy a position between the ganglia and extend behind the dorsal ganglia (Fig. 41). The excretory tubules are large and the anterior caecum has forward branches but they are far be- hind the brain. I have separated this worm from the other Amphiporids on its size, colour and innervation of the proboscis. The armature was not seen. The specimen was male. Amphiporus scoresbyi, (Figs. 42, 43). Three specimens of this small distinctively shaped species were obtained at St. WS 302 (N 77), the colour note being "orange-yellow to orange- red dorsally and ventrally with very pale yellow periphery and proboscis. Darker pigment in mid- line posteriorly". Two specimens were taken at St. WS 548 and one at St. WS 550. These were of the same size and shape. They had been preserved in formalin and all colour was bleached. Form and colour of preserved specimens. The body is fusiform, the length 5-5 mm., diameter of the mid-body 2-0 mm. Its surface is thrown into small rounded eminences which at the anterior end form three or four rows of short fimbriae (Fig. 42). The colour is uniformly yellowish with no sign
